xi Abstract of Thesis Presen ted to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Master of Science MONITORING SOIL MOISTURE AND SO IL WATER SALINITY IN THE LOXAHATCHEE FLOODPLAINS By Amanda E. Mortl August 2006 Chair: Rafael Muoz-Carpena Major Department: Agricultur al and Biological Engineering Vegetation studies conducted along the Loxahatchee River show that the highly valued baldcypress have been retreating upstream since the tu rn of the century. It is believed that the increasing salinity in the Loxahatchee River and the altered hydroperiod makes it impossible for the baldcypress to thrive. The goal of this study was to characterize soil moisture and salinity ch anges in the floodplain during wet and dry seasons by using a combined dielectric probe that measures soil moisture and salinity after specific calibration. Although this type of sensor responds quickly to changing soil moisture, is easy to use in automated data collection systems and is moderately priced, the relationship between dielectric constant and soil moisture/ salinity significantly changes for high water content and organic soils, of which little is known about the dielectric response. The calibration results for the Winder sand we re similar to the manufacturer calibration, but the fluvent and Terra Ceia muck so ils resulted in an entirely new and unique calibration. While calibration in the case of the Winder sand increases

PAGE 12

xii the range of accuracy, without such calibrations meaningful measurements in the fluvent and Terra Ceia muck soils are not possible. Once the probes were calibrated, two floodplai n transects perpendicular to the river were monitored for 18 months. Transect 1 is upstream and baldcypress dominated,and Transect 7 represents a transition between fres hwater tolerant baldc ypress and salt water tolerant mangroves. Data obtained from the probes suggested that soil water salinities increase in the surface soils (0-30 cm) of gr eater elevation and distance from the river during dry periods in the upstream freshwater transect. Soil water salinities stayed relatively constant and low in the flooded areas of this transect. In the downstream transect, which exhibits mangr ove invasion, soil moisture re mained relatively constant. Data suggest that pore water salinity varies based on river water salinity during the dry season, although it is difficult to quantify, as observed changes were minimal. Since this transect remained saturate d much of the study period, a longer monitoring period is necessary to study soil mois ture/salinity relations duri ng drier times when seedling recruitment is likely to occur.

1 CHAPTER 1 INTRODUCTION Loxahatchee River and the Importan ce of its Floodplain Ecosystem The Loxahatchee River is located on the east side of the lower peninsula of Florida, and its watershed drains approximately 210 s quare miles that lie between Palm Beach and Martin counties. The Loxahatchee River has three main tributaries: the North Fork, the Northwest Fork, and the Southwest Fork (Fig ure 1-1). These three tributaries join at the Loxahatchee Estuary Central Embayment, which connects to the Atlantic Ocean via Jupiter Inlet. The watershed includes protected areas such as Jonathan Dickinson State Park, Loxahatchee Slough Preserve, Jupite r Ridge Natural Area and J.W. Corbett Wildlife Management Area. Figure 1-1. Loxahatchee Rive r and Estuary (SFWMD, 2002)

PAGE 14

2 The Northwest Fork is historically a fres hwater ecosystem and is home to one of the last remnants of native cypress rive r-swamp within southeast Florida. Species diversity is high here due to the overlapping of tropical and temperate vegetation communities On May 7, 1985 a 7.6 mile portion of the Northwest Fork of the Loxahatchee River was designated as the first Wild and Scenic River in Florida. A Wild and Scenic designation provides for a means of protecting the rivers wate r quality and preserving it in its natural condition. The main goal of the national program is to preserve the outstanding characters of a rive r, not to halt nearby development, which is why the term living landscape is often applied to these ri vers (The National Wild and Scenic Rivers Program, 2004). The outstanding characteristic s of the Northwest Fork are the species that make up the freshwater floodplain swamp community. Statement of Problem Although the freshwater ecosystem of the No rthwest Fork area is highly valued, it is showing signs of stress and is rece ding. Vegetation studies conducted along the Loxahatchee River show that the highly valued baldcypress have been retreating upstream since the turn of th e century. The 1855 General Land Office Township Plats & Field Survey Notes report that saltwater to lerant mangroves were present only up to the confluence of the North, Northwest and Southw est Forks of the River near the Jupiter Inlet, near river mile 6 (General Land Offi ce, 1855). It is also noted that freshwater indicator species such as bald cypress, cabbage palms, wa x myrtle, pop ash and bay were upstream in the riverine swamp. The S outh Florida Water Management District (SFWMD) analyzed aerial photographs fr om 1940 and determined that mangrove swamps primarily resided downstream of ri ver mile 7.8, and the furthest downstream

PAGE 15

3 evidence of freshwater swamp can be found at river mile 5.8. A 1940 vegetation map of the Northwest Fork of the Loxahatch ee River is presented in Figure 1-2. Figure 1-2. Vegetation along the Northwest Fork of the Loxahatchee River in 1940 (SFWMD, 2002) Figure 1-3. Vegetation along the Northwest Fork of the Loxahatchee River in 1995 (SFWMD, 2002)

PAGE 16

4 By the late 1940s, mangroves had migrated up to Kitching Creek, near river mile 8 (SFWMD, 2002). In just under one hundred years, the mangroves had retreated upstream about 2 miles. An aerial photograph of the floodplain in 1995 (Figure 1-3) shows that mangrove swamps were present up to river mile 9.6 and dominant between river miles 5.5 and 8.7. By 2002, mangroves represented ov er 75% of the plan t community up to river mile 9.2 (SFWMD, 2002). The State of Florida requires Water Manageme nt Districts to make a priority list of rivers and schedule for their establishment of minimum flows and levels. Minimum Flows and Levels (MFL) are designed to pr otect the ecology and water resources of a river from temporary loss of water resource functions which result from a change in surface or ground water hydrology that takes mo re than two years to recover (Section 373.042(1) F.S.). Chapter 373 protects water re source functions such as flood control, water quality, water supply and storage, fi sh and wildlife protection, navigation and recreation. The Loxahatchee River in southeast Flor ida is among the many rivers that have been scheduled for MFLs in the state. The SFWMD adopted a Minimum Flows and Levels Rule, Chapter 40E-8, Florida Admini strative Code, in 2003, which included an MFL for the Northwest Fork. This legi slation requires a R ecovery Strategy for restorative flows to the ecosystem, which was implemented using the latest and best available scientific and technical informa tion. The Recovery Strategy applies to the following segments of the river and thei r corresponding valued ecosystem components (VEC) (South Florida Water Management District, 2006): Cypress swamp and hydric hammock in the freshwater riverine floodplain (River Mile [RM] 16 to RM 9.5),

PAGE 17

5 Cypress swamp in the tidal floodplain (RM 9.5 to RM 5.5), Fish larvae in the low salinity zone (RM 9.5 to RM 5.5), Oysters in the mesohaline zone (RM 6.0 to RM 4.0) and, Seagrasses in the polyhaline zone downstream (RM 4.0 to RM 0.0). Requirements for the Freshwater Ecosystem Wetlands are particularly sensitive to hydrologic change. Changes to the wetland hydrologic characteristics change the wetla nds physiochemical features, including oxygen and nutrient availabilit y, pH, toxicity, salinity and sediment deposition. A wetlands hydrology and physiochemical environm ent is directly rela ted to its species composition and richness, primary productiv ity and organic accumulation (Mitsch and Gosselink, 2000). These hydrologic changes in the Northwest Fork may be directly affecting vegetation composition, and theref ore baldcypress population, along the river. Hydroperiod, the seasonal pattern of wate r stage in a wetland, is known to be the dominant environmental factor controlling th e ecological characteristics of a swamp. Hydroperiod length significantly affects the composition of flora and fauna community structure and associated wetland functions (Mitsch and Gosselink, 2000). Baldcypress trees are the most flood-toleran t tree species in Florida. However, even baldcypress need seasonal dry periods for their seedlings to grow tall enough to survive future flooding. In 1990, Conner and To liver found that cypress regenerate well when seedbeds are moist and competitors ar e unable to cope with flooding (Conner and Toliver, 1990). Otherwise, faster growing hardwoods would outcompete. Although seeds cannot germinate when the soil is floode d, they do well when the soil is saturated (Dickson and Boyer, 1972). It is important for cypress to have fluctuating water levels. If seedlings are submerged for a long period of time during the growing season, they will

PAGE 18

6 not survive (Keeland and Conner, 1999). Howeve r, if seedlings are even barely exposed above flooding conditions, they are capable of surviving (Penf ound, 1949). This may explain how many cypress stands are of the same age, and that regeneration commonly occurs during extended periods of low water levels (Matoon, 1915; Putnam et al. 1960). Another factor to consider in baldcypress management is salinity. Baldcypress are considered to be only slightly tolerant to salinity, and are generally salt-sensitive (Brown and Montz, 1986; Pezeshki et al. 1986, 1987). Krauss et al. (1999) exposed baldcypress seedlings to 0, 2, 4, or 6 g/L salinity. Incr easing salinity had a signi ficant negative impact on root elongation and adventiti ous root growth on all seedli ngs. Allen et al. (1994) found the survival, height growth, leaf area, and total biomass of seedlings from 5 fresh and 10 brackish water sources a ll to decline with increasing salinity. Mean survival of seedlings from all 15 sources was 100% at a sali nity of 0 ppt, 99% at 2 ppt, 95% at 4 ppt, 83.5% for 6 ppt, and 72.5% for 8 ppt. Not a lo t of research has been done on the salinity tolerance of baldcypress tr ees (Conner and Askew 1992), particularly mature trees. The SFWMD has thus concluded that there is not sufficient evidence for establishing a chronic salinity threshold to seedlings or matu re trees, or an acute threshold for seedlings (SFWMD, 2002). These vegetation changes are concurrent with dramatic hydrologic changes in the landscape. Rodis (1973) conclu ded from his observations of the Loxahatchee River that saltwater migration upstream was the primar y cause of its environmental decline. The Northwest Fork is experiencing a ltered hydroperiod and increasing salinity (SFWMD, 2002). Major factors that contribute to the drastic changes include: 1) the construction of canals which drain water away from the historic river basin of the

PAGE 19

7 Loxahatchee; 2) the construction of the C-18 canal which transferred a majority of the Northwest Fork headwaters to the Southw est Fork (Figure 1-1); 3) the permanent opening, by the US Army Corps of Engineers, of the Jupiter Inlet, historically an intermittent barrier to saltwater intrusion (Figure 1-1), and 4) the lowering of the groundwater table in the watershed by co mmunity consumption (SFWMD, 2002). Some of these changes are further discussed below. Before the drainage and urbanization periods, the Northwest Fork of the Loxahatchee River received flow from the Loxahatchee Marsh (S lough) and Hungryland Slough, south of Lainhart dam. Since the turn of the century, the drai nage patterns of the area have been highly altered. The canals, le vees and drainage ditches transecting the watershed have lowered the water table a nd increased the speed of drainage. One of the first hydrologic changes wa s the construction of the Masten and Lainhart Dams in the 1930s. They were constructed by two families in order to slow down water flow between Indiantown Road (n ear river mile 13) and Trapper Nelsons Settlement (near river mile 10) as a meas ure of flood control. In the 1940s, the construction of Bridge Road and Jenkins Di tch, and the introducti on of citrus and sod farming further reduced flows to the Nort hwest Fork via Kitching Creek. Between 1940 and 1953, Federation Canal and Hobe Grove Ditc h were dredged to aid in irrigating the citrus groves. Soon after, sod farming became more popular. In 1957-1958, Canal C-18 was built for flooding protection through the head waters of the Northwest Fork in the Loxahatchee Slough. This canal redirected fl ow from the Northwest Fork to the South Fork until 1974, when the G-92 structure was built to reconnect Canal C-18 and the Loxahatchee Slough with the Northwest Fork (SFWMD, 2002). This means that the

PAGE 20

8 Loxahatchee drainage patterns that were on ce controlled by the poorly defined landforms of the area are now controlled by man-made control structures Canal 18, the Florida Turnpike, I-95, State Road 710 and secondary can als that have been developed by special drainage districts and landowne rs within the basin. The hydrology at the mouth of the Loxahatche e Estuary (Jupiter Inle t) has also seen drastic hydrological changes. Historically, J upiter Inlet naturally opened and closed due to variation in flow from Loxahatchee Ri ver, Jupiter River, Jupiter Sound and Lake Worth Creek. During drought, the inlet silted up and prevented saltwater from entering the estuary or the river. During the wet season, the high freshwater flows opened the inlet and prevented saltwater intrusion. At the turn of the century, the Intracoastal Waterway and the Lake Worth Inlet was constructed, and the St. Lucie Inlet was modified. This diverted some of the flow responsible for keeping the Jupiter Inlet open, which caused the inlet to close. In 1947, Jupiter In let was permanently opened by the United States Army Corps of Engineers (USACE) (SFWMD, 2002). The size of the catchment area has also been reduced; the historic watershed was defined solely by topography and containe d 699 square kilometers, currently the watershed is defined by topography as well as man-made features and it encompasses only 544 square kilometers. Studies Related to Restor ation of the Bald Cypress To mitigate baldcypress migration, studies have been conducted to decipher the minimum flows necessary for the baldcypres s to thrive. However, the relationship between river flow and baldcypress regenera tion is not explicitly understood (SFWMD, 2002). For example, a study (Dent, 1997) at the Northwest Fork determined that hydrologic changes that shorten the length of this meandering river allow higher salinity

PAGE 21

9 levels further upstream, as well as a smaller time buffer between salinity changes at two locations along the river. Another study s hows that there is an inverse relationship between surface water flow and salinity concen trations in this river (Dent and Toliver, 1990). However, the surface water salinity data generated cannot be directly applied to the baldcypress being protected. Baldcypr ess mostly obtain water from the floodplain shallow groundwater and the vadose zone. Th e salinity values of these media are also important factors for baldcypress health. In order for the articles mentioned above to have more direct value, a relationship betw een river stage and gr oundwater levels, soil moisture and soil water salinity concentrations would need to be established that takes into consideration position in the floodplain( distance from stream and elevation) and soil type. McPherson and Halley (1996) documented the encroachment by the mangroves, along with the overall reductions in freshwater flows, main tenance of lower groundwater levels, short duration high volume freshwater flows for flood prot ection, and changes in the quality of runoff. There have been onl y a few studies addressing the effects of groundwater on ecology in the floodplain of th e Loxahatchee River. In 2000, Shaw and Huffman describe the hydrology of isolated wetlands of south Florida, including a wetland in Jonathan Dickinson State Par k, and how these wetlands are affected by lowering groundwater elevation. Also in 2000, Mercado conducte d a study on Kitching Creek basin that included groundwater. The id ea that vegetation change in the transition zone between freshwater vegetation to saltw ater tolerant mangroves is dynamically related to seasonal ch ange in salinity, groundwater leve ls and microtopography in the floodplain has only been confirmed by anecdotal observati on (USGS, 2004).

10 Performance measures were developed for each river segment, or VEC, to evaluate the ecological effects of severa l proposed restoration flow a lternatives. They were used to relate flow of the river and subsequent salinity wedge to the ecological needs of each river segment. Three hydrologic and salinity models we re used to formulate and evaluate restoration alternatives: a watershed hydrologic model (WaSH) (SFWMD, 2006), RMA (Army Corps of Engineers, 1996) and a l ong-term salinity model (LSMM) (SFWMD, 2006). WaSH simulates long-term freshwater tributary inflows tributaries to the Northwest Fork, RMA simulates short-term influences of these inflows and tide on estuarine salinity and LSMM was developed fr om the results of RMA to predict daily estuary salinity values to be used in the WaSH model (SFWMD 2006). The SAVELOX model also has potential to pr ovide insight on ecological chan ges due to different salinity conditions and to predict fr eshwater conditions needed for protection of the VECs (SFWMD 2006). It was developed with RM A-2 and RMA-4 (Army Corps of Engineers, 1996) to simulate salinity conditions along th e river for a 3-year period since long-term salinity data was not available for all surveyed vegetation transects. The extensive collection of sc ientific observations, along wi th the utilization of the three models mentioned above and public input were used to generate three variable flow scenarios that emulate natural seasonal changes in flow. Ultimately, a Preferred Restoration Flow Scenario was chosen that allows for vari able dry season flow between 50 and 110 cubic feet per second (cfs) and requires the dry season mean of 69 cfs over Lainhart Dam. Also, flows are augmen ted when flows are below 70 cfs between February and May, below 130 cfs between Augus t and November and 80 cfs for all other,

PAGE 23

11 transitional months. The plan also require s augmented flows to downstream tributaries when the total flow of the river is below 300 cfs (SFWMD, 2006). The vast collection of data obtained thus far along with th e three Loxahatchee hydrological and salinity models do not yet incl ude soil pore water sa linity and the effects of floodplain soil type on the possibility of restoration. Working knowledge of the hydrology and salinity in the floodplain should be used to validate the Preferred Restoration Flow Scenario. For example, th e effect of river flow on soil moisture and soil water salinity in the floodplain would brid ge the gap between our knowledge of the effects of river flow and salinity over th e soil moisture requirements and salinity thresholds of the baldcypress. River fl ow together with local floodplain seasonal precipitation will affect soil mo isture in the floodplain differently based on the elevation and location of the soil and the soils prope rties. This applies as well to salinity. To have a detailed picture of this rela tionship, one must have a sufficiently large network of observation points within the floodplain. To have many observation points, the instruments used must be affordable. A combined dielectr ic probe (Hydra Probe, Stevens Water Monitoring Systems Inc., OR ) measuring soil moisture, salinity and temperature at the same point, is potentially one such instrument. It is moderately priced, can be placed in near soil surface positions and be used easily with automated data collection systems. However, to obtain the mo st reliable data from this probe, it must be calibrated specifically to the soil it monitors. Research Objectives The following objectives were achieved by this study: Calibrate the Hydra probe used for monito ring the floodplain to th e soils specific to the freshwater riverine and tidal floodplains (Chapter 2)

13 CHAPTER 2 CALIBRATION OF A COMBINED DI ELECTRIC PROBE TO LOXAHATCHEE RIVER FLOODPLAIN SOILS Synopsis A combined dielectric probe (Hydra Probe ) measuring soil moisture, salinity and temperature is evaluated for a wide range of soils (from mineral soils to organic muck) present in the Loxahatchee Rive r floodplains. The probes adva ntage is that it responds quickly to changing soil moisture, is easy to use in automated data collection systems and is moderately priced (Muoz-Carpena et al ., 2005b). However, the relationship between dielectric constant and soil moisture/ salinity significantly changes for high water content and organic soils, of which little is k nown about the dielectric response. To calibrate, samples of the three major soil series (Winder sand, Fluvent and Terra Ceia muck) collected from the area were p acked to field density and treated to a combination of 25 different soil moisture and wa ter salinity levels (5x5). The 4-electrode probe took independent measurem ents of bulk electrical con ductivity, pore water salinity by a laboratory electrical conductivity meter (ranging from 0.01 10 S/m observed in the area) and soil moisture was controlled by the Richards plates and measured by gravimetric methods. Voltage values from the combined dielectric probe were taken at each combination of soil moisture and salinit y. The calibration results for the sand were similar to the manufacturer calibration, but the fluvent and muck soils resulted in an entirely new and unique calibration. While calibration in the case of the sandy soil increases the range of accur acy, without such calibrations meaningful measurements in the fluvent and muck so ils are not possible.

14 Introduction The Hydra combined dielectric probe ( Stevens Water Monitoring Systems, Inc., Beaverton, Oregon ) is used in a variety of field pr ojects to monitor soil moisture, temperature and soil water salinity (e.g., US Department of the Interior Bureau of Reclamation Pacific Northwest Region, Soil Climate Analysis Network of the Natural Resource Conservation Service) (Stevens, 2006). The USDA has used its sensing technology for over 10 years (Stevens, 2006), and NASA uses it to validate data obtained from their Advanced Microwave Scanning Radiometer Earth Observing System (Jackson and Cosh, 2003). This sensor can be used in a wide range of environmental conditions including freezing soils and it responds quickly to changing soil moisture. It works well with near surface positioning, is easy to use in automated data collection systems and is moderately priced and accura te after calibration (Muoz-Carpena et al., 2005b). It also has potential for use in ot her projects, such as tracking saline contaminants in the soil, i.e. nitrate u nder intensive horticultural systems (MuozCarpena et al., 2005b). The probe determines soil moisture and bulk electrical conductivity by measuring the soil dielectric properties (Campbell, 1990) based on three analog readings (0 2.5 V DC). Dielectric permittivity ( ) is directly related to the dielectrical constant, K and the permittivity of free space ( o) by the following equation: = K o, where (2-1) K = r i i (2-2) K is a complex number composed of real ( r) and imaginary ( i) dielectric constants (Campbell, 1990). Through calibra tion, real and imaginary diel ectric constant can be related to soil moisture ( ) and bulk electri cal conductivity ( a), respectively (Seyfried

PAGE 27

15 and Murdock, 2004). With these known, the pore water salinity ( w) can be estimated through additional calibration. In the case of soil moisture, Topp et al. (1980) found a general model that relates the r of granular mineral soil s to soil moisture through a third order polynomial. However, the largest source of uncertainty in measuring soil moisture and temperature corrected soil pore water conductiv ity with this probe is from variation in response from different soil types (Seyfried and Mu rdock, 2004). Topps equation tends to underestimate in soils with high clay content (Dirksen and Da sberg, 1993) and highly organic soils like peat (Shibchurn et al ., 2005). It also performs poorly with volcanic soils due to a greater por tion of bounded water from their low bulk densities and large surface areas (Regalado et al., 2003). However, the real dielectric constant measured by the 50 Mhz Hydra probe is more sensitive to variations of soil type, particularly clay content and clay type, than other probes th at use a higher sampling frequency (Shibchurn et al., 2005). In addition, resu lts from other dielectric probes show that these soils require special calibration (Shi bchurn et al., 2005). The Hydra probe was originally calibrated for the Hart sand, the Wilder silt and the Ft. Edwards clay (Campbell, 1990). Since the n, The Hydra probe has been calibrated for measurement of soil moisture in the gravelly sand of the Dry Valleys region of Antarctica (Wall et al., 2004), a very gravelly sandy loam comprised of mixed calcareous alluvium from Arizona, and other various loams (Seyfried et al., 2004). In the case of i, Campbell et. al (1990) presented th e relationship with the soil bulk electrical conductivity ( a) where: a = ( 0) i. (2-3)

PAGE 28

16 where 0 is the permittivity in free space with a value of 8.85x10-12 and is the angular frequency that for this probe is 5x107 Hz. Due to the variability of this probes response to different soil types, calibration is necessary, especially for non-mineral soils. The Loxahatchee Floodpl ain project is an ongoing effort that is attempting to set Mi nimum Flows and Levels (MFLs) for the Loxahatchee River in southeast Florida (SFWMD, 2002) to protect the endangered freshwater ecosystem of the area. Soil wa ter conductivity and moisture data along the floodplain where organic soils are present ar e needed to evaluate recent river flow standards adopted in the area. The Hydra probe is being used to monitor salinity and soil moisture along the floodplain where these hydr ic soils present a wide range of organic matter content and textures that require a soil specific calibration. The objective of this study was to calibra te the Hydra probe to a wide range of organic and mineral soils specific to the L oxahatchee River Watershed. Soil moisture and bulk electrical conductivity relationships vs. probe outpu ts (analog voltage readings 0-2.5V DC) were obtained for a combinati on of controlled moisture and salinity conditions and then were related to por e water conductivity w ith various models proposed in the literature. Materials and Methods Sampling and Soil Characterization From May 18-24, 2004 a detailed soil survey was conducted to classify soils in the Loxahatchee floodplain accordi ng to drainage class and series by the USDA-Natural Resource Conservation Service (Kevin Sullivan, personal communication). Two transects, perpendicular to the river, were chosen to be monitored. These transects, Transect 1 and Transect 7, are re presentative of an unaffected freshwater

Surface elevation and location of probes along experimental Transect 7 Based on this characterization and the location of the Hydra probes in the floodplain, the major types of soil being mon itored that encompass a wide range of inorganic-organic content were selected for calibration of the Hydra probe. The three main soil types were the Winder sand, fluve nt and Terra Ceia muck (Chapter 3).

PAGE 31

19 In late summer 2004, undisturbed and dist urbed soil samples were taken from soil near the location and depth that each Hydra pr obe was installed (see Figures 2-2 and 2-3). These samples were used to calibrate the pr obes to the site-specifi c soil and obtain soil moisture characteristic curves. The samples were analyzed fo r porosity and bulk density ( b) using the core method, and saturated hy draulic conductivity ( Ks) using the constant head method (Klute, 1986). Specific density was calcula ted from bulk density results ( S). Residual ( r) and saturated soil moisture ( s) values were also determined. The r for the fine sand is an average of the lowest values found by the three probes because the water table dropped significantly below each probe. This va lue was confirmed during the calibration procedure, where the sand experien ced up to 333 cm of pressure in the pressure extractor. Since soil moisture in the fluvent and the mu ck never decreased to residual values, we estimated r values based on soil survey valu es for this soil (USDA, 1981). s for the sand and the muck were calculated after de termining bulk density of each and then weighing a known volume of each after saturating them. Equipment Hydra probe The Hydra probe is composed of a pr obe head, a multiconductor cable and four probe sensing tines (see Figure 2-4). The probe head generates a 50 MHz electrical signal and the cable carries the 4 output DC data cha nnel voltages (0 2.5 V DC) nd provides 12VDC power. The four sensing (three outer and one center) tines form the sensing volume (diameter 3 cm, length 5.7 cm) of soil from which electrical response is measured.

PAGE 32

20 Figure 2-4. Hydra probe sensor (Stevens, 2006) A) Multiconductor cable. B) Probe head. C) Four probe sensing tines. Four analog outputs are genera ted from the probe, three of the voltage values are used to calculate the real ( r) and imaginary ( i) dielectric consta nts using algorithms provided by the manufacturer, which are then us ed to characterize the electrical response of the soil. The fourth voltage is used to calculate soil temperat ure. The temperature corrected (25 C o) real dielectric constant is used to calculate soil moisture, and the temperature corrected (25 C o) imaginary constant is directly related to the bulk electrical conductivity of the soil ( a). Soil pore water salinity ( w) is calculated by using a and is dependent on calculated soil moisture ( ). Four-electrode probe The four-electrode (4e) probe method (F igure 2-5) was first developed by Wenner (1915), and has been used to evaluate soil water content and salinity under field conditions since 1931 (McCorkle, 1931). The 4e probe measures resi stivity (inverse of bulk conductivity) by passing an alternating curre nt between the two outside electrodes. The change in voltage ( ) is measured between the two in ner electrodes. The ratio of the voltage and current is used to determine electrical resistance ( ER ) (Gupta and Hanks, (a) (b) (c)

PAGE 33

21 1972), which can then be calibrated into the bulk conductivity of the soil sample (Rhoades, 1976; Nadler and Fr enkel, 1980). The following equa tion is used to calculate bulk electrical conductivity: ER = K / I (2-4) Where K is the geometric coefficient related to the geometrical arrangement of the probes and I is the electrical current used. In this case, the following equation wa s used, where the distance between each probe is the same: K = 2 d where (2-5) d is the distance between the probes. In order to measure conductivity, the probe s can be arranged as necessary, but the geometric coefficient will change accordingl y. The Wenner arrangement indicates that the distance between all of the 4 probes is the same. This calibration uses an arc arrangement around a circle, where all probes are equidistant but at a slight angle to one another. The bulk conductivity obtained by the circular four-electrode probe is comparable to the original linear ar ray salinity probes (N adler et al., 1982). These cells were made of PVC pipe with a height long enough to fit the combined dielectric probe (5.26 cm diameter, 5.96 cm height, 129.51 cm3 volume). Eight bolts were inserted into the side around the cell equidistant from e ach other (average distance = 1.64 cm) and protruding into the cell (Figure 2-5). For calculating bulk elect rical conductivity or a, we used the average distance between the bolts for each individual cell to decrease error as shown in Figure 2-5.

22 Figure 2-5. 4-electrode probe Pressure extractor Pressure Extractors (see Figure 2-6) generally used to gene rate soil moisture curves are used here to control the moisture level of the samples. Saturated soil samples are placed in the extractor (pressure chamber) on ceramic plates and a known pressure is applied, forcing the soil water through the pr essure plate and out of the extractor. Pressures of 0, 10, 50, 100, 150 and 33cm were a pplied to the Winder sand and pressures of 0, 10, 20, 30 and 40 cm were applied to th e Terra Ceia muck and fluvent. These represent an equivalent draw-downs in water table observed at the experimental site of the Loxahatchee River (Chapter 3). Pressure s did not exceed the maximum pressure that the plates could withstand. Plates with maximum bubbling pressures of 1000 cm and 5000 cm were used.

Calibration procedure Sub-samples of each soil type were packed to field density into the cells described above for measurement by the 4-electrode probe A total of 180 cells were packed for each of the three soil series, representing 5 pore water salinity levels (0.01, 0.1, 0.25, 0.5 and 1 S/m observed in the area), 4-5 soil moisture levels (0, 10, 50, 100, and 333 cm for the sand and smaller increments ranging from 0 to 40 cm for the fluvent and muck) and 3 replicates for each soil moisture and salinity co mbination. Soil packed into cells used for saturated soil measurements were re-used in the same cell for 10 cm suction measurements after establishi ng the original conditions. Figure 2-7.

24 Once packed, the cells were soaked to satu rate the soil and flushed with one of the five NaCl solutions represen ting the 5 pore water conductivitie s specified above. At least three pore volumes were used for flushing, unt il the drainage solution reached a constant electrical conductivity value as measured with a handheld electrical conductivity probe (AP50 pH/Ion/Conductivity Me ter, Denver Instrument Co mpany). Similar to the procedure implemented by Nadler and Fra nkel (1983), it was assumed that once the outflow had the same conductivity as the inflow, that the mobile pore water space, or soil water had that conductivity. Af ter saturation, the bo ttom of the soil cores were sealed with parafilm paper (previously zeroed on th e scale) and then weighed to determine gravimetric soil moisture. Eight resistivity measurements were taken around the core to determine bulk conductivity (Figure 2-7) and voltage values from the combined dielectric probe were taken (Figure 2-8). Water was extracted with pressure plate extractors at pre-selected suction values (0 333 cm), after which th e 4-electrode and the Hydra probe readings were obtained. The samples were weighed after each measurement to obtain volumetric soil moisture content. Three replicates were used for each moisture/salinity combination, and measurements were repeated for each soil moisture level. From the data acquired through the process above, a soil moisture characteristic curve was obtained and the relationships between the r vs. and between i vs. bulk electrical conductivity as m easured by the 4e probe was determined. A polynomial model similar to Topps (1980) and a lin ear equation were used respectively.

We then found the relationship between a (as measured by the 4-electrode probe) and w (as measured by the handheld EC meter) using several proposed models. Four models for the relationship between a and w were tested. The first model, a linear model (Linear 1) was first proposed by Rhoades et al. in 1976 a = T w + s, where (2-6) T = a +b (2-7) and a and b are empirical constants. Therefore, for a fixed a = (a 2 + b ) w + s (2-8) assumes a linear relationship between a and w and considers the tortuosity ( T ) of the soil, which is expressed as a linear function of s represents the electrical conductivity of the soils solid phase, and in some soils, like coarse sand, can be as low as zero. A second linear (Linear 2) model proposed for volcanic soils (Muoz-Carpena et al, 2005a), (a) (b) (c) (d)

PAGE 38

26 a = (a 2 + b ) w + c 2 (2-9) replaces the s term from the linear model with s depending on 2. Rhoades et al. proposed (1989) a non-linear model for soils that do not exhibit a linear relationship between a and w at a fixed for low values of w a = [ (c +d)] w + (( sol + c +d) 2)/ sol, where (2-10) where c and d are empirical constants and sol = b / S. Here, compared to Equation 2-7, s is not considered constant a nd the equation includes the effect of solute distribution in the mobile pore water. The last model is an empirical model derived from results obtained using aggregated volcanic soils (Vogeler et al., 1996), a = (c d) w + (a b), with c > d and a > a b. (2-11) Although this equation offers additional flexibility compared to the other three equations, it lacks physical basis and incr eases the number of parameters needed (4 vs. 2 and 3 for the previous models). Results and Discussion Soil Characterization Tables 2-1 and 2-2 show soil descriptions for this fieldwork. Winder fine sand is located at the higher ground at Transect 1 (see Figure 4), wh ile the lower area that is periodically flooded was characterized by Kevi n Sullivan as a fluvent interbedded clay and sand, with sand content increasing with depth (K. Sullivan, personal communication, May, 2004). The Winder fine sand is poorly dr ained, nearly level soil and is found in broad, low flats and depressions (USDA, 1978). Typically, the water table is within 25 cm of the surface for 2 to 6 months in a y ear. A fluvent is a st ratified entisol whose development is hindered by frequent flooding and deposition (Sumner, 2000).

The soil descriptions show that there are tw o major mineral soil series at Transect 1 (Winder fine sand and fluvent), and one major organic soil series that is being monitored at Transect 7 (Terra Ceia muck). Physical properties of the soils sampled ar e presented in Table 2-3. The samples of the fluvent at Transect 1 have bulk density va lues of 0.65 (g/cm3) or less at soil depths between 0-60 cm indicating the high organi c content and unconsolidated nature. The

PAGE 40

28 average of 2 samples taken from soils from 60 90 cm is 1.15, a bulk density more typical of soil with higher mi neral content and is closer in value to the upland Winder sand. The hydraulic conductivity of the fluvent shows a wide range of values regardless of depth. The higher average hydraulic conductiv ity values of the fluvent over the sand may be due to the unconsolidated nature of the fluvent. As expected, the Winder sand has low percent carbon values (organic matter), while the fluvent has values that almost reach the definition of an organic soil, >12% organic carbon (Sumne r, 2000). Testing for cation exchange capacity is still in progress. The soil encountered at Tran sect 7 is Terra Ceia muck (USDA, 1981). It typically has a very low bulk density and hydraulic condu ctivity and is an organic soil as shown by percent carbon results. Table 2-3.

Soil moisture characteristic curve for soils studied The fluvent and muck both have higher soil moisture values at each pressure step than the sand. These soils were not exposed to pressure steps as high as the sand, at higher pressure levels the muck and the fluve nt shrink and volumetric soil measurements are no longer possible. Also, when the soils lose contact with the wall of the 4e probe, bulk electrical conductivity measurements ar e impossible. This does not present a limitation to this study since in f act, the range tested is still similar to the range seen in the field. Organic soils are known to shri nk irreversibly when dried beyond some threshold not normally experi enced in natural conditions. Soil Moisture Calibration Figure 2-10 shows the relationship between th e real dielectric c onstant and percent soil moisture of the Hart sand that Campbell (1990) originally used to calibrate the Hydra probe. It also shows the same relations hip with the Winder Fine sand from the Loxahatchee River floodplain. The point of greatest dive rgence between the two is at high water content.

The range of measure real dielectric constant for this soil is 3. 95 25.88, with an average, 12.86. The relationship between real dielectric c onstant and percent soil moisture for the muck and the fluvent are shown in Figure 2-11. Table 2-4 shows the parameters and goodness of fit of this relationship for each soil series. The manufacturer did not calibrate the probe for similar soils, so these are unique calibration equations.

Imaginary dielectric constant vs. bulk electrical conduc tivity as measured by the 4e probe The sand results presented in Figure 2-12 confirm the values built into the program provided by the manufacturer to process raw da ta from the probes. The muck and the fluvent show a slight deviation from this relationship, which suggests that the high organic matter content of these soils al so has an influence on this relationship. By comparing the slop e of the relationship i vs. a for sand found on Figure 2-12 with Equation 2-3, we find that it is necessary to introduce a constant, kc that embodies both the instrument characteristic s and the soil series. This is a modification of Equation 2-3. The new equation becomes: = (kc* 0) i (2-12) Since permittivity in free space ( 0) is 8.85x10-12 and the angular frequency ( ) is =5x107 Hz, then it follows that kc =6.554 for the sand, and 4.52 for the fluvent and muck.

The Vogeler empirical model pe rformed best for all soil types (highest r2), and the best performing of the physical based models for the sand and fluvent soils is the non-linear model. For the sand, the linear (Rhoades et al., 1976) model slightly over predicts a at low a values. For the muck, the non-linear (Rhoade s et al., 1989) slight ly under predicts a at all low a values and for most high a values. The Vogeler et al (1996) equation fits best, especially at low a values in all cases and will be selected for calibration of the field values from the experimental site. The Vogeler et al. (1996) equation was selected in the Loxahatchee River monitoring project as it is th e overall best fitting model.

35 Limitations A major limitation to the ca libration methodology is that it is better suited for mineral soils. When organic or high clay soils experience dry they often shrink. This prevents reliable measurements for volumetr ic soil moisture beyond a certain soil suction (or equivalent water table drawdown. Fortunate ly, these soils in fi eld conditions did not experience the drawdown that causes this shri nkage, but it is not out of the realm of possibility, and the experiment did not prepar e the probe calibration fo r that situation. Conclusions A combined dielectric probe measuring real and imaginary components of the dielectric constant, r and i, was calibrated to three major soil series found in the floodplains of the Northwest Fork of Loxaha tchee River, the Winder sand, a fluvent and the Terra Ceia muck. r and i were used to determine and a respectively. So far, this combined dielectric probe has rarely been cal ibrated to highly organic soils. This may be due to its unique behavior, i.e. its high shri nk/swell potential that makes it difficult to work with in the lab. Unique relationships were found between r and for each of the soils. Unique yet similar relationships were also found between i and a for each soil. Four equations that relate w and a were tested to estimate a. All four equations performed well, however the empirical Voge ler et al. (1996) equa tion performed best across all three soil series. This may be a re sult of its additional flexibility due to an additional equation parameter (4 against 2 or 3 for other equations). This calibration is among the first attempts to characterize a gr oup of soils representing a wide range of organic matter content. These results show that the combined dielectric probe, in conjunction with its unique calibration for each soil series and previously proposed equations relating w, and a, can be used in the Loxa hatchee floodplain soils as a

37 CHAPTER 3 HYDROPERIOD AND SOIL WATER SALI NITY IN THE BALD CYPRESS FLOODPLAINS OF THE LOXAHATCHEE RIVER Synopsis The Northwest Fork of the Loxahatchee Rive r is home to one of the last remnants of native cypress river-swamp within the s outhern-most continental United States. Vegetation studies conducted along the Loxahatchee River sh ow that the highly valued baldcypress have been retreati ng upstream since the turn of th e century. It is believed that the increasing salinity in the Loxahatchee River and the altered hydroperiod makes it impossible for the baldcypress to thrive. The goal of this study is to characterize so il moisture and salinity changes in the floodplain during wet and dry seasons. Two fl oodplain transects perpendicular to the river were monitored for one year. Twelve combined dielectric probes measuring soil moisture, salinity and temperature were insta lled on each transect (3 depths x 4 distances from the river) for one wet and dry season. Additional hydrological data was obtained from the SFWMD on river flows and stages, lo cal rainfall and local groundwater salinity and elevation. Data obtained from the probes su ggest that soil water salinities increase in the surface soils (0-30 cm) of greater elevati on and distance from the river during the end of the dry season in the upstream freshwater transect. Soil water salinities stayed relatively constantand low (below thegener ally accepted 2 ppt or 0.3125 S/m threshold for baldcypress) in the flooded area s of this transect. Increase in soil water salinity in the surface soil was concurrent with decreasing so il moisture. In the downstream transect, which exhibits mangrove invasion, soil moistu re remainedremains relatively constant.

38 Data suggest that pore water salinity varies based on river water salinity during the dry season, although it is di fficult to quantify, as observed changes were subtle. Rela tionships found between hydrological data and salinity show that minimum flows and le vels adopted on the river for the protection of the baldcypress maintain saturated conditions at the probe locations and low salinity in the fluvent soil in Transect 1. During the study period, Transect 7 remained so saturated that the conditions may have been responsible for any failure of bald cypress to germinate, yet salinity remained below threshold values. Since this transect remained saturated much of the study period, a longer monitoring period is necessary to study soil moisture/salinity relations during drier times. Introduction The Loxahatchee River is located on east si de of the lower peninsula of Florida (26o 59 N, 80o 9 E), and its watershed drains ap proximately 210 square miles that lie between Palm Beach and Martin counties. The Loxahatchee River has three main tributaries: the North Fork, the Northwest Fork, and the Southwest Fork. These three tributaries join at the Loxahatchee Estuar y Central Embayment, which connects to the Atlantic Ocean via Jupiter Inlet. The waters hed includes protected areas such as Jonathan Dickinson State Park, Loxahatchee Slough Preser ve, Jupiter Ridge Natural Area and J.W. Corbett Wildlife Management Area. The Northwest Fork is historically a fres hwater ecosystem and is home to one of the last remnants of native cypress rive r-swamp within southeast Florida. Species diversity is high here due to the overlapping of tropical and temperate vegetation communities. Due to hydrological alteration in the watershed, the freshwater ecosystem

39 of the Northwest Fork is showing signs of stress and is receding. Vegetation studies conducted along the Loxahatchee River show th at the freshwater tolerant baldcypress have been retreating upstream since the tu rn of the century. In 1855, the saltwater tolerant mangroves were present only up to the confluence of the North, Northwest and Southwest Forks of the River near the Jupi ter Inlet, near river mile 6 (FDEP, 1855) Figure 1 shows the vegetation changes in the floodplain from 1940 to 1995. In 1995, the mangrove swamps were present up to river mile 10.4 and dominant between river miles 5.5 and 8.7. By 2002, mangroves represented ov er 75% of the plan t community up to river mile 9.2 (SFWMD, 2002). Baldcypress n eed freshwater conditions to thrive and variation in hydroperiod to germin ate and outcompete other plants.

Florida requires water management districts to ma ke a priority list and schedule for the establishment of minimum flows and levels Minimum Flows and Levels (MFL) are designed to protect the ecology and water resources of a ri ver from temporary loss of water resource functions which result from a change in surface or ground water hydrology that takes more than two years to recover (Section 373.042(1) F.S.). Chapter 373 protects water resource functions such as flood control, wate r quality, water supply and storage, fish and wildlife protection, na vigation and recreation. Current Northwest Fork Loxahatchee River MFLs do not consid er soil type, soil moisture or salinity distribution within the floodplain. A new MFL was proposed by the South Fl orida Water Management District (SFMWD) in 2006 (SFWMD, 2006). A Prefe rred Restoration Flow Scenario was chosen that allows for variable dry season flow between 50 and 110 cubic feet per second

PAGE 53

41 (cfs) and requires the dry season mean of 69 cfs over Lainhart Dam. Also, flows are augmented when flows are below 70 cfs between February and May, below 130 cfs between August and November and 80 cfs for al l other, transitional months. The plan also requires augmented flows to downstream tr ibutaries when the total flow of the river is below 300 cfs (SFWMD, 2006). It is de signed to allow enough flows to maintain freshwater conditions in the VECs that re quire it and to preven t excessive drawdown. The main objective of this study is to characterize soil moisture and salinity changes in the floodplain during wet and dr y seasons and buld response functions of these variables vs. river flow values. Th is study will ultimately help the SFWMD to evaluate recently adopted MFLs based on cr itical floodplain soil moisture and salinity data. Materials and Methods Hydrological Data Two floodplain transects perpendi cular to the river, one impacted (Transect 7, river mile 9.1) and one non-impacted (Transect 1, river mile 14.8) were monitored for one wet and dry season. Combined probes measuring soil moisture, salinity and temperature with data loggers were installed on each transect at 4 locations and 3 depths (Figure 3-3 and 34). The probes were programmed to take these three measurements every half hour. Transect 1 has one well at the higher elevati on portion of the transect (Figure 3-3). Transect 7 has four wells. Three of the four wells are located near the soil moisture/ salinity probes (Figure 3-4).

43 determine the relationship between surface water and groundwater for the hydroperiod analysis by combining it with the groundwater data. The Loxahatchee watershed receives about 61 inches annually w ith a median value of 57 inches. Total annual rainfall can ra nge between 38 and 93 inches. Most of the precipitation, about two thir ds, occurs during the wet season, which is May through October. The highest rainfall usually occurs in September at about 8.7 inches, and the lowest rainfall occurs during December, Janua ry and February at 2.3 2.8 inches per month (SFWMD, 2002). In south Florida, evapotranspiration accounts for about 45 inches of water loss per year (SFWMD, 2002) The SFWMD provides local rainfall data and evapotranspiration estimates for future studies. Soil Data Undisturbed and disturbed soil samples were taken from soil near the location and depth that soil moisture/ salinity probes were to be installed. The samples were analyzed for bulk density ( b) using the core method and sa turated hydraulic conductivity (Ks) using the constant head method (Klute, 1986). The samples will also be used to calibrate the probes to the site-specific soil and obtain soil moisture characteristic curves. Monitoring Instruments Soil moisture ( ), salinity (w) and temperature were continuously monitored by combined dielectric probes (Hydra Probe, St evens Water Monitoring Systems Inc., OR). Figure 2 shows the placement of the probes fo r Transects 1 and 7 respectively. Each cluster of 3 probes was connected to a fiel d data logger (CR10 Campbell Scientific UT) (Figure 3-5).

44 Figure 3-5. Datalogger box C with probes 7-9 underneath located in Transect 1 This type of sensor responds quickly to changing soil moisture. It works well with near surface positioning, is easy to use in automated data collection systems, is moderately priced, and is accurate after ca libration (Muoz-Carpena, 2004). However, the relationship between dielectric constant and soil moisture/salinity significantly changes for high water content and organic so ils. Also, relatively low electrical conductivity distorts data unless correcti ons are made, and the higher electrical conductivity values distort soil moisture estimations to values lower than the actual value. Since some soils in the Loxahatchee floodplain are organic, many have been flooded for a majority of the monitoring period, and both high and low conductivity values will be measured for both transects, it is essential to calibrate this probe. The largest source of uncertainty in measuri ng temperature corrected soil water conductivity is from variation in response from different soil types. Work to reduce the uncertainty Datalogger box

45 through calibration of the instrument with site -specific soils is curre ntly under way in a separate effort (Chapter 2). To scale the field values for different soil series, soil moisture data will be reported as effective soil moisture, on a range of 0 -1. Effective soil moisture is calculated by the following equation: Se = r / s r (3-1) where r = residual soil moisture and s = soil moisture at saturation. Results and Discussion Winder fine sand was found to be located at the higher ground at Transect 1, while the lower area that is periodi cally flooded is a fluvent soil series characterized by interbedded clay and sand, with sand content increasing with depth (K. Sullivan, personal communication, May, 2004). A fluvent is a stratified entisol whose development is hindered by frequent flooding and deposition (Sumner, 2000). The samples taken from this horizon have very high variability due to its in terbedded horizons. The soil encountered at Transect 7 is Terra Ceia muck. Table 1 shows the range of soil characteristics for each transect. Table 3-1.

48 Figure 3-6 shows local preci pitation, and river flow at the Lainhart dam (near Transect 1) during the monito ring period and effective soil moisture and soil pore water salinity for the probe sets farthe st and closest to the river. Figure 3-7 shows local rainfall, stage at Transect 7 and effective soil moisture and salinity for the pr obe sets farthest and closest to the river. Transect 7 is tidally in fluenced and flow values are not available. Groundwater data (water tabl e and groundwater salinity) are currently being processed by the SFWMD. The floodplains experience low rainfall from October through February and higher rainfall in the spring through the summer. On September 25th, 2004 Hurricane Jeanne passed through the study area. The rain from Hurricane Jeanne caused a major increase in flow at Lainhart dam and stage at Transect 7 (Figures 3-6 and 3-7). Stage also increased noticeably at Transect 7. Flow le vels generally follow changes in rainfall throughout the year at Transect 1. Stage at Tr ansect 7 is affected by flow, but it is also tidally influenced. Soil moisture at Probe 1 increases to saturation or near saturation on June 30, 2005 to July 1, 2005 during times of rai n, but there was not a significant increase in the deeper probes in the probe set. The d eeper soils were already near saturation at the time. At Transect 1, soil moisture is influe nced by rain and river stage height. At Transect 1, there is an increase in soil salini ty as the soil moisture decreases. This is likely due to the concentration of salts as water evaporates ra ther than an input of saline water. To date, it is still difficult to obtain a complete picture of soil moisture and soil water salinity response to hydrological c onditions throughout both transects for the monitoring period since probes 6 24 were inst alled later than probes 1 6, after most of the winter dry season had past, and equipm ent difficulties caused lapses in data.

PAGE 61

49 However, relationships can be discovered with what data ar e available. Table 3-2 shows the range of soil moisture and soil wate r salinity throughout the monitoring period. Probes 1 3 are located highest in elevati on at Transect 1 and furthest from the Northwest Fork (Figure 3-3). These probes e xperience the highest range in soil moisture, and soil pore water salinity. The high soil mois ture range at Probes 1 -3 is due to their exposure to flooding and rain during the we t season and during the dry season, their distance and difference in elevation from the river.

Overall, probes 10 12 have a lower range in moisture due to their proximity to the river. The

PAGE 62

50 river has a higher influence on these probes. For probes 10 12, Probe 10 has the highest soil moisture range compared with the other two probes that are the same distance from the river; there is a corresponding high range of soil water salinity exhibited at probe 10. Soil moisture values at probes 13 24 (Transec t 7) have low standard deviations due to their elevation since it is a relatively flat transect and a ll of the transect is exposed to tides, so the soil moisture throughout the transe ct is influenced relatively equally by the river height. These soils are saturated or cl ose to saturated for most of the entire observation period. At the probe location furthest from the river at Transect 1, the range of salinity decreases, and the average yearly salinity decreases with depth. The shallower probes experience greater salinity increas es since they are influenced more by evapotranspiration. The shallowe st probe at the probe location closest to the river (Probe 10) also has a larger range in salinity than the deepest probe (Probe 12), but a slightly lower average salinity. Relationship between Stage at Lainhart Dam and Soil Moisture at Transect 1 Figure 3-9 shows river stage at Transect 1 at specific flows over Lainhart Dam. These points were used to develop the relatio nship between flow and stage at Transect 1 shown by Figure 3-10.

Figure 3-9 also shows vegetation types as elevation changes. Figure 3-9. Flow at Lainhart Dam vs stage at Transect 1(SFMWD, 2006) Figure 3-9 shows that stage drops significantl y as flow decreases which is confirmed by our results comparing flow with soil moisture.

PAGE 64

52 Figure 3-10 shows that the soil at the probe location furthest from the river, which is also of the highest ground elevation, require s a higher flow in orde r to reach saturation. Figure 3-10. Relationship between the flow ra te at Lainhart Dam and effective soil moisture in the baldcypress floodplain at different distances from the stream and soil depths The soil at the two probe locations closest to the river never desaturates during the time period studied. At Transect 1, the bald cypress primarily live near the two probe locations closest to the river, giving way to the types of vegetation (hammock) at further and higher ground locations in the transect. According to these re sults, the current MFL will allow for flows that keep the soil at the probe locations closest to the river saturated. Note that the shallowest probe s in the fluvent (both probe sets) are 0.25 meters below soil surface. Figure 3-10 does not indicate when the soil surface is flooded. Baldcypress are able to germinate when soils are moist but not flooded.

The fit may improve if factors such as antecedent rainfall, or microtopography is considered in future studies. A graph cr eated by the SFWMD (2005) helps to illustrate this (Figure 3-8). Figure 3-8 shows the e ffect of microtopography on the flooded area. The floodplain elevation is sli ghtly lower at about 160 feet from the reference point compared with the elevation at 290 feet from th e reference point, the edge of the river. This area (160 ft) becomes flooded before the so il closest to the river, which may explain why the set of probes close to this depressi on record higher soil moisture values for the same river flow levels as the set of probes closest to the river.

PAGE 66

54 Time of rainfall may also be an important factor in the relationship between soil moisture and river stage, particularly in the sand, which has very low water holding capacity. For example, although river flow le vels may be very high due to a previous rainfall, the stage may not be high enough to satu rate the soil at the probe locations in the sand. Since sand has a very low water holdi ng capacity, it may be quite dry even though soil of lower elevation or higher water holding ca pacity is wet or saturated from previous rainfall or high river flow levels. Relationship between Flow and Po re Water Salinity at Transect 1 Salinity generally increases once the soil is desaturated, most likely from both concentration of salts by evapotranspiration a nd low flow levels. However, even though salinity increases during times of low soil moisture, pore water salinity remains low most of the year and the when the salinity va lues did increase to above the 0.3125 S/m baldcypress salinity threshold, the longest contin uous time period where values remained above the threshold was less than one week. No definitive pattern was observed relating pore water salinity to river flow. This may be due in part because calculated (using calibration equations explained in Chapter 2) pore water salinity values are dependant on soil moisture, therefore any noise seen in Fi gure 3-10 will carry over into the relationship between pore water salinity and flow. This means that the antecedent rainfall and microtopography discussed above may also need to be considered for this relationship. Relationship between Stage and Eff ective Soil Moisture at Transect 7 Stage at Transect 7 remains high enough relative to soil surf ace elevation that almost continuous saturation of the soil is ma intained. Even while salinity levels were below salinity threshold values for the baldcypr ess, there is only a limited time that water levels draw down enough to allow baldcypress seed germination if at all. The time

PAGE 67

55 period that this transect was monitored was during a notoriously wet period with several hurricanes and large storms passing through. The average elevation of the lower floodplain is 0.46 m, while the average river st age for the monitoring period was 0.26 m. This means that water levels in the floodplain remained very close to the surface. Lower stages than observed during th is time period may be needed in order to find a clearer relationship between soil moisture and stage. Monitoring, particularly during the dry season or drier years, should be continued to further this exploration. Factors Associated with Salinity at Transect 7 At Transect 7, salinity increases at the surface probe furthest from the river during a closely related increase in river salinity in early February 2005. This occurs at the conclusion of a dry period and corresponding lo wer flows at Lainhart Dam. The salinity in the river reaches salinity le vels about twice that of the pore water salinity, which could indicate the river as the source of the salinity rather than groundwater recharge. Also, the peak of the river salinity is on Feb. 5 and the middle of the salinity peak for the shallow probe is 20 days later, which may indicate a la g. Unfortunately, due to difficulties with the field equipment, data from probes located cl oser to the river is not available. Perhaps if we had this data, it would show a peak in sa linity as well, but closer in time to the peak of salinity at the river. This would confirm the above explanation for the behavior of the changes in salinity. After this dramatic incr ease in river salinity, it returns to previous levels and remains stable. Meanwhile, the por e water salinity at the probes closest to the river decrease with time to levels closer to those found at the pr obes furthest from the river. This decrease in salinity may indicat e that, with increase water to the watershed, freshwater is flushing out th e floodplain and feeding the ri ver, instead of during drier periods when the river may be the water s ource to the floodplain. There may be a

56 seasonal variation as the sour ce of the water in the floodplai n (the river vs. watershed) that affects the pore water salinity in the floodplain The fact that we see salinity levels be low the baldcypress salinity threshold during the entire monitoring period may be due to th e many rainfall events that maintain high water levels. Monitoring during a drier period may show increases in salinity to values higher than we see during this monitoring peri od. Figure 3-7 shows that the Loxahatchee River may be a source of salinity to the floodplain during the end of the dry season. During periods with even lower flows, we ma y see the same pattern but with salinity peaks with higher values. Continued monitori ng is suggested to e xplore the relationship between river stage and pore water salinity. Performance of the Instrumentation System The methodology of the experiment require d using a combined dielectric probe, which was used with a datalogger consisti ng of an interface plat e and the CR-10 CPU, and a battery power supply. The field condi tions were extreme, with extended flooding conditions, a humid environment, thriving vegetation and fauna, tourist access and natural disasters. Despite these difficult cond itions, a large amount of reliable data was collected. Each of the four were subject to failure at different times of the experiment. Failure may have been caused by weather. Fo r, example all probes at Transect 7 failed between 11:00 and 11:30 pm on October 5th, the same time as when a large storm was passing through. Unfortunately, the failure pr evented us from collecting potentially valuable data. Conclusion This study supports current res earch in best management pr actices of this nationally valued ecosystem. Evaluating the hydroperiod and soil moisture salinity values in both

PAGE 69

57 an unaffected and affected transect along the river shows characteristic differences in the soil moisture and salinity of two differen t ecosystems, one freshwater baldcypress swamp, the other in the tran sition zone between mangroves and baldcypress. Also, the study shows the effect of soil type on the possibility of freshwat er restoration. Transect 1 represents the unaffected fres hwater ecosystem. Here, shallow upland soil experiences greater salinity, most likely from the concentration of salts as soil moisture values decrease from evapotranspi ration. The depressional areas experience a smaller range in salinity and are saturated for most to all of the year. Soil moisture relates closely with stage of the river and rainfall, and th e values found at each probe depend on distance from the river and elevati on. The SFWMD can use the relationships generated by the data to evaluate current minimum flows and levels for the Northwest Fork of the Loxahatchee River. Since bald cypress health is dependent on freshwater conditions and varying soil mois ture throughout the year, this information is critical to the regeneration of the baldcypress. The rela tionship of flow vs. soil moisture shows that for the proposed MFL (dry season flow betw een 50 cfs and 110 cfs with a mean flow of 69 cfs over Lainhart Dam), the soil moisture at the probe locations in the fluvent at Transect 1will not change much and remain at saturation. The shallow sandy soil will have effective soil moisture values close to zero. The MFL values will also maintain salinity below the 2ppt (S/m) level established at this transect. Salinity also remained below threshold values at Transect 7, and soil moisture values remained high. Since this the transects were observed during relativel y wet periods, and generally hydroperiod is the driving factor for salinity values, it is necessary to cont inue monitoring to capture the interannual variability of the hydroperiod and its subseque nt effect on pore water salinity in the floodplain.

58 CHAPTER 4 CONCLUSION Through extensive work and collabora tion, the SFWMD has collected much information about the hydrodynamic and salinity changes of the Northwest Fork of the Loxahatchee River. There is a solid unders tanding of the relations hip between the flow of the river from its many tributaries, its stage and the resultant salinity wedge. Detailed vegetation data have been collected since 1940 that allows us an understanding of the alarming vegetation changes over time, believe d to be due to hydrological changes over time, both natural and man-made. Long-term tr ends in salinity of the river have been modeled to predict resultant vegetation types. This knowle dge serves as a foundation for the evaluation of restoration flow alternatives and the formulation of an MFL. However, very little was known of the dynamics between the river and its fl oodplain. Effects of soil type on restoration potential throughout the floodplain had not been studied. This study addresses that paucity of understanding. Soil moisture, temperature and salinity were measured at 4 locations and 3 depths along two transects, each representing differe nt ecological functions along the rivera freshwater riverine wetland and a transitional, tidally-influenced transect with both mangroves and baldcypress. The transects were monitored starting from September 2004, and data are still being collected at the time of publication. Data through March 2006 are presented in this paper. The comb ined dielectric probe measuring real and imaginary components of the dielectric constant, r and i,, was used for monitoring and was calibrated to the soils specific to the area to provide meaningful values. This probe

PAGE 71

59 has many benefits including the ability to w ithstand the harsh environments found in the floodplain, and calibration helps it overcome its obstacles. It was calibrated to three major soil series found in the floodplains of the Northwest Fork of Loxahatchee River, the Winder sand, a fluvent and the Terra Ceia muck. r and i were used to determine and a respectively. Unique relationships were found between r and for each of the soils. Unique yet similar relationships were also found between i and a for each soil. Four equations that relate w and a were tested to estimate a. All four equations performed well, however the empirical Voge ler et al. (1996) equa tion performed best across all three soil series. This calibration is among the first attempts to characterize a group of soils representing a wide range of organic matter content. After monitoring and the calibration of the di electric probe, we have a much better understanding of the behavior of the floodplai n soils in both of these transects. Surprisingly, salinity reached higher levels at the unaffected sitein the higher elevation sand that is the driest area of both transects. It is believed that salinity increase here is from the concentration of salts due to evapotra nspiration, whereas the variation in salinity at Transect 7 is caused by th ehydroperiod and salinity levels in the river. The probes closest to the river at Transect 7 see a slig ht decrease in salinity over time after the wet season starts while the probes furthest from the river see an increase in salinity at the end of the dry season. This is only prelimin ary evidence suggesting that the relationship between the elevation of the groundwater a nd the river changes seasonally. Obtaining processed groundwater data will substantiate or refute this proposal. Overall, results obtained from this study support the Preferre d Restoration Flow Scenario and make it more robust.

60 Future research. During the completion of this experiment, many questions were raised as others were answered. Some suggestions for future work in order to expand upon what has been built in this thesis document are as follows: Continue field data collection to be tter quantify soil moisture and soil water salinity dynamics in the floodplain. Incorporate groundwater data into the general hydrologic analysis. Use observed data and fundamental prin ciples to develop a robust numerical simulation (Hydrus 2-D, others) with the ability to simulate long-term hydrological and salinity changes for the entire floodplain. Derive physically-based functional relations hips for soil moisture and soil water salinity for integration into a management-based modeling tool, such as QND. Use these relationships and previous/ ongoing vegetative research to build a predictive model of ecosystem dynamics and hydrology-induced community changes.

MONITORING SOIL MOISTURE AND SOIL WATER SALINITY IN THE
LOXAHATCHEE FLOODPLAINS

By

Amanda E. Mortl

August 2006

Chair: Rafael Mufioz-Carpena
Major Department: Agricultural and Biological Engineering

Vegetation studies conducted along the Loxahatchee River show that the highly

valued baldcypress have been retreating upstream since the turn of the century. It is

believed that the increasing salinity in the Loxahatchee River and the altered hydroperiod

makes it impossible for the baldcypress to thrive. The goal of this study was to

characterize soil moisture and salinity changes in the floodplain during wet and dry

seasons by using a combined dielectric probe that measures soil moisture and salinity

after specific calibration. Although this type of sensor responds quickly to changing soil

moisture, is easy to use in automated data collection systems and is moderately priced,

the relationship between dielectric constant and soil moisture/ salinity significantly

changes for high water content and organic soils, of which little is known about the

dielectric response. The calibration results for the Winder sand were similar to the

manufacturer calibration, but the fluvent and Terra Ceia muck soils resulted in an entirely

new and unique calibration. While calibration in the case of the Winder sand increases









the range of accuracy, without such calibrations meaningful measurements in the fluvent

and Terra Ceia muck soils are not possible.

Once the probes were calibrated, two floodplain transects perpendicular to the river

were monitored for 18 months. Transect 1 is upstream and baldcypress dominated,and

Transect 7 represents a transition between freshwater tolerant baldcypress and salt water

tolerant mangroves. Data obtained from the probes suggested that soil water salinities

increase in the surface soils (0-30 cm) of greater elevation and distance from the river

during dry periods in the upstream freshwater transect. Soil water salinities stayed

relatively constant and low in the flooded areas of this transect. In the downstream

transect, which exhibits mangrove invasion, soil moisture remained relatively constant.

Data suggest that pore water salinity varies based on river water salinity during the dry

season, although it is difficult to quantify, as observed changes were minimal. Since this

transect remained saturated much of the study period, a longer monitoring period is

necessary to study soil moisture/salinity relations during drier times when seedling

recruitment is likely to occur.















CHAPTER 1
INTRODUCTION

Loxahatchee River and the Importance of its Floodplain Ecosystem

The Loxahatchee River is located on the east side of the lower peninsula of Florida,

and its watershed drains approximately 210 square miles that lie between Palm Beach

and Martin counties. The Loxahatchee River has three main tributaries: the North Fork,

the Northwest Fork, and the Southwest Fork (Figure 1-1). These three tributaries join at

the Loxahatchee Estuary Central Embayment, which connects to the Atlantic Ocean via

Jupiter Inlet. The watershed includes protected areas such as Jonathan Dickinson State

Park, Loxahatchee Slough Preserve, Jupiter Ridge Natural Area and J.W. Corbett

Wildlife Management Area.

The Northwest Fork is historically a freshwater ecosystem and is home to one of

the last remnants of native cypress river-swamp within southeast Florida. Species

diversity is high here due to the overlapping of tropical and temperate vegetation

communities.

On May 7, 1985 a 7.6 mile portion of the Northwest Fork of the Loxahatchee River

was designated as the first 'Wild and Scenic River' in Florida. A 'Wild and Scenic'

designation provides for a means of protecting the river's water quality and preserving it

in its natural condition. The main goal of the national program is to preserve the

outstanding characters of a river, not to halt nearby development, which is why the term

"living landscape" is often applied to these rivers (The National Wild and Scenic Rivers

Program, 2004). The outstanding characteristics of the Northwest Fork are the species

that make up the freshwater floodplain swamp community.

Statement of Problem

Although the freshwater ecosystem of the Northwest Fork area is highly valued, it

is showing signs of stress and is receding. Vegetation studies conducted along the

Loxahatchee River show that the highly valued baldcypress have been retreating

upstream since the turn of the century. The 1855 General Land Office Township Plats &

Field Survey Notes report that saltwater tolerant mangroves were present only up to the

confluence of the North, Northwest and Southwest Forks of the River near the Jupiter

Inlet, near river mile 6 (General Land Office, 1855). It is also noted that freshwater

indicator species such as bald cypress, cabbage palms, wax myrtle, pop ash and bay were

upstream in the riverine swamp. The South Florida Water Management District

(SFWMD) analyzed aerial photographs from 1940 and determined that mangrove

swamps primarily resided downstream of river mile 7.8, and the furthest downstream











evidence of freshwater swamp can be found at river mile 5.8. A 1940 vegetation map of


the Northwest Fork of the Loxahatchee River is presented in Figure 1-2.

By the late 1940s, mangroves had migrated up to Kitching Creek, near river mile 8

(SFWMD, 2002). In just under one hundred years, the mangroves had retreated upstream

about 2 miles. An aerial photograph of the floodplain in 1995 (Figure 1-3) shows that

mangrove swamps were present up to river mile 9.6 and dominant between river miles

5.5 and 8.7. By 2002, mangroves represented over 75% of the plant community up to

river mile 9.2 (SFWMD, 2002).

The State of Florida requires Water Management Districts to make a priority list of

rivers and schedule for their establishment of minimum flows and levels. Minimum

Flows and Levels (MFL) are designed to protect the ecology and water resources of a

river from "temporary loss of water resource functions which result from a change in

surface or ground water hydrology that takes more than two years to recover (Section

373.042(1) F.S.)." Chapter 373 protects water resource functions such as flood control,

water quality, water supply and storage, fish and wildlife protection, navigation and

recreation.

The Loxahatchee River in southeast Florida is among the many rivers that have

been scheduled for MFLs in the state. The SFWMD adopted a Minimum Flows and

Levels Rule, Chapter 40E-8, Florida Administrative Code, in 2003, which included an

MFL for the Northwest Fork. This legislation requires a Recovery Strategy for

restorative flows to the ecosystem, which was implemented using the latest and best

available scientific and technical information. The Recovery Strategy applies to the

following segments of the river and their corresponding valued ecosystem components

(VEC) (South Florida Water Management District, 2006):

Cypress swamp and hydric hammock in the freshwater riverine floodplain
(River Mile [RM] 16 to RM 9.5),









Cypress swamp in the tidal floodplain (RM 9.5 to RM 5.5),

Fish larvae in the low salinity zone (RM 9.5 to RM 5.5),

Oysters in the mesohaline zone (RM 6.0 to RM 4.0) and,

Seagrasses in the polyhaline zone downstream (RM 4.0 to RM 0.0)."

Requirements for the Freshwater Ecosystem

Wetlands are particularly sensitive to hydrologic change. Changes to the wetland

hydrologic characteristics change the wetlands physiochemical features, including

oxygen and nutrient availability, pH, toxicity, salinity and sediment deposition. A

wetlands hydrology and physiochemical environment is directly related to its species

composition and richness, primary productivity and organic accumulation (Mitsch and

Gosselink, 2000). These hydrologic changes in the Northwest Fork may be directly

affecting vegetation composition, and therefore baldcypress population, along the river.

Hydroperiod, the seasonal pattern of water stage in a wetland, is known to be the

dominant environmental factor controlling the ecological characteristics of a swamp.

Hydroperiod length significantly affects the composition of flora and fauna community

structure and associated wetland functions (Mitsch and Gosselink, 2000).

Baldcypress trees are the most flood-tolerant tree species in Florida. However,

even baldcypress need seasonal dry periods for their seedlings to grow tall enough to

survive future flooding. In 1990, Conner and Toliver found that cypress regenerate well

when seedbeds are moist and competitors are unable to cope with flooding (Conner and

Toliver, 1990). Otherwise, faster growing hardwoods would outcompete. Although

seeds cannot germinate when the soil is flooded, they do well when the soil is saturated

(Dickson and Boyer, 1972). It is important for cypress to have fluctuating water levels.

If seedlings are submerged for a long period of time during the growing season, they will









not survive (Keeland and Conner, 1999). However, if seedlings are even barely exposed

above flooding conditions, they are capable of surviving (Penfound, 1949). This may

explain how many cypress stands are of the same age, and that regeneration commonly

occurs during extended periods of low water levels (Matoon, 1915; Putnam et al. 1960).

Another factor to consider in baldcypress management is salinity. Baldcypress are

considered to be only slightly tolerant to salinity, and are generally salt-sensitive (Brown

and Montz, 1986; Pezeshki et al. 1986, 1987). Krauss et al. (1999) exposed baldcypress

seedlings to 0, 2, 4, or 6 g/L salinity. Increasing salinity had a significant negative impact

on root elongation and adventitious root growth on all seedlings. Allen et al. (1994)

found the survival, height growth, leaf area, and total biomass of seedlings from 5 fresh

and 10 brackish water sources all to decline with increasing salinity. Mean survival of

seedlings from all 15 sources was 100% at a salinity of 0 ppt, 99% at 2 ppt, 95% at 4 ppt,

83.5% for 6 ppt, and 72.5% for 8 ppt. Not a lot of research has been done on the salinity

tolerance of baldcypress trees (Conner and Askew 1992), particularly mature trees. The

SFWMD has thus concluded that there is not sufficient evidence for establishing a

chronic salinity threshold to seedlings or mature trees, or an acute threshold for seedlings

(SFWMD, 2002).

These vegetation changes are concurrent with dramatic hydrologic changes in the

landscape. Rodis (1973) concluded from his observations of the Loxahatchee River that

saltwater migration upstream was the primary cause of its environmental decline.

The Northwest Fork is experiencing altered hydroperiod and increasing salinity

(SFWMD, 2002). Major factors that contribute to the drastic changes include: 1) the

construction of canals which drain water away from the historic river basin of the









Loxahatchee; 2) the construction of the C-18 canal which transferred a majority of the

Northwest Fork headwaters to the Southwest Fork (Figure 1-1); 3) the permanent

opening, by the US Army Corps of Engineers, of the Jupiter Inlet, historically an

intermittent barrier to saltwater intrusion (Figure 1-1), and 4) the lowering of the

groundwater table in the watershed by community consumption (SFWMD, 2002). Some

of these changes are further discussed below.

Before the drainage and urbanization periods, the Northwest Fork of the

Loxahatchee River received flow from the Loxahatchee Marsh (Slough) and Hungryland

Slough, south of Lainhart dam. Since the turn of the century, the drainage patterns of the

area have been highly altered. The canals, levees and drainage ditches transecting the

watershed have lowered the water table and increased the speed of drainage.

One of the first hydrologic changes was the construction of the Masten and

Lainhart Dams in the 1930s. They were constructed by two families in order to slow

down water flow between Indiantown Road (near river mile 13) and Trapper Nelson's

Settlement (near river mile 10) as a measure of flood control. In the 1940s, the

construction of Bridge Road and Jenkin's Ditch, and the introduction of citrus and sod

farming further reduced flows to the Northwest Fork via Kitching Creek. Between 1940

and 1953, Federation Canal and Hobe Grove Ditch were dredged to aid in irrigating the

citrus groves. Soon after, sod farming became more popular. In 1957-1958, Canal C-18

was built for flooding protection through the headwaters of the Northwest Fork in the

Loxahatchee Slough. This canal redirected flow from the Northwest Fork to the South

Fork until 1974, when the G-92 structure was built to reconnect Canal C-18 and the

Loxahatchee Slough with the Northwest Fork (SFWMD, 2002). This means that the









Loxahatchee drainage patterns that were once controlled by the poorly defined landforms

of the area are now controlled by man-made control structures Canal 18, the Florida

Turnpike, 1-95, State Road 710 and secondary canals that have been developed by special

drainage districts and landowners within the basin.

The hydrology at the mouth of the Loxahatchee Estuary (Jupiter Inlet) has also seen

drastic hydrological changes. Historically, Jupiter Inlet naturally opened and closed due

to variation in flow from Loxahatchee River, Jupiter River, Jupiter Sound and Lake

Worth Creek. During drought, the inlet silted up and prevented saltwater from entering

the estuary or the river. During the wet season, the high freshwater flows opened the

inlet and prevented saltwater intrusion. At the turn of the century, the Intracoastal

Waterway and the Lake Worth Inlet was constructed, and the St. Lucie Inlet was

modified. This diverted some of the flow responsible for keeping the Jupiter Inlet open,

which caused the inlet to close. In 1947, Jupiter Inlet was permanently opened by the

United States Army Corps of Engineers (USACE) (SFWMD, 2002).

The size of the catchment area has also been reduced; the historic watershed was

defined solely by topography and contained 699 square kilometers, currently the

watershed is defined by topography as well as man-made features and it encompasses

only 544 square kilometers.

Studies Related to Restoration of the Bald Cypress

To mitigate baldcypress migration, studies have been conducted to decipher the

minimum flows necessary for the baldcypress to thrive. However, the relationship

between river flow and baldcypress regeneration is not explicitly understood (SFWMD,

2002). For example, a study (Dent, 1997) at the Northwest Fork determined that

hydrologic changes that shorten the length of this meandering river allow higher salinity









levels further upstream, as well as a smaller time buffer between salinity changes at two

locations along the river. Another study shows that there is an inverse relationship

between surface water flow and salinity concentrations in this river (Dent and Toliver,

1990). However, the surface water salinity data generated cannot be directly applied to

the baldcypress being protected. Baldcypress mostly obtain water from the floodplain

shallow groundwater and the vadose zone. The salinity values of these media are also

important factors for baldcypress health. In order for the articles mentioned above to

have more direct value, a relationship between river stage and groundwater levels, soil

moisture and soil water salinity concentrations would need to be established that takes

into consideration position in the floodplain(distance from stream and elevation) and soil

type.

McPherson and Halley (1996) documented the encroachment by the mangroves,

along with the overall reductions in freshwater flows, maintenance of lower groundwater

levels, short duration high volume freshwater flows for flood protection, and changes in

the quality of runoff There have been only a few studies addressing the effects of

groundwater on ecology in the floodplain of the Loxahatchee River. In 2000, Shaw and

Huffman describe the hydrology of isolated wetlands of south Florida, including a

wetland in Jonathan Dickinson State Park, and how these wetlands are affected by

lowering groundwater elevation. Also in 2000, Mercado conducted a study on Kitching

Creek basin that included groundwater. The idea that vegetation change in the transition

zone between freshwater vegetation to saltwater tolerant mangroves is dynamically

related to seasonal change in salinity, groundwater levels and microtopography in the

floodplain has only been confirmed by anecdotal observation (USGS, 2004).









Performance measures were developed for each river segment, or VEC, to evaluate

the ecological effects of several proposed restoration flow alternatives. They were used

to relate flow of the river and subsequent salinity wedge to the ecological needs of each

river segment.

Three hydrologic and salinity models were used to formulate and evaluate

restoration alternatives: a watershed hydrologic model (WaSH) (SFWMD, 2006), RMA

(Army Corps of Engineers, 1996) and a long-term salinity model (LSMM) (SFWMD,

2006). WaSH simulates long-term freshwater tributary inflows tributaries to the

Northwest Fork, RMA simulates short-term influences of these inflows and tide on

estuarine salinity and LSMM was developed from the results of RMA to predict daily

estuary salinity values to be used in the WaSH model (SFWMD 2006). The SAVELOX

model also has potential to provide insight on ecological changes due to different salinity

conditions and to predict freshwater conditions needed for protection of the VEC's

(SFWMD 2006). It was developed with RMA-2 and RMA-4 (Army Corps of Engineers,

1996) to simulate salinity conditions along the river for a 3-year period since long-term

salinity data was not available for all surveyed vegetation transects.

The extensive collection of scientific observations, along with the utilization of the

three models mentioned above and public input were used to generate three variable flow

scenarios that emulate natural seasonal changes in flow. Ultimately, a "Preferred

Restoration Flow Scenario" was chosen that allows for variable dry season flow between

50 and 110 cubic feet per second (cfs) and requires the dry season mean of 69 cfs over

Lainhart Dam. Also, flows are augmented when flows are below 70 cfs between

February and May, below 130 cfs between August and November and 80 cfs for all other,









transitional months. The plan also requires augmented flows to downstream tributaries

when the total flow of the river is below 300 cfs (SFWMD, 2006).

The vast collection of data obtained thus far along with the three Loxahatchee

hydrological and salinity models do not yet include soil pore water salinity and the effects

of floodplain soil type on the possibility of restoration. Working knowledge of the

hydrology and salinity in the floodplain should be used to validate the Preferred

Restoration Flow Scenario. For example, the effect of river flow on soil moisture and

soil water salinity in the floodplain would bridge the gap between our knowledge of the

effects of river flow and salinity over the soil moisture requirements and salinity

thresholds of the baldcypress. River flow together with local floodplain seasonal

precipitation will affect soil moisture in the floodplain differently based on the elevation

and location of the soil and the soil's properties. This applies as well to salinity.

To have a detailed picture of this relationship, one must have a sufficiently large

network of observation points within the floodplain. To have many observation points,

the instruments used must be affordable. A combined dielectric probe (Hydra Probe,

Stevens Water Monitoring Systems Inc., OR) measuring soil moisture, salinity and

temperature at the same point, is potentially one such instrument. It is moderately priced,

can be placed in near soil surface positions and be used easily with automated data

collection systems. However, to obtain the most reliable data from this probe, it must be

calibrated specifically to the soil it monitors.

Research Objectives

The following objectives were achieved by this study:

* Calibrate the Hydra probe used for monitoring the floodplain to the soils specific to
the freshwater riverine and tidal floodplains (Chapter 2)






12


* Characterize soil moisture and salinity changes in these floodplains during wet and
dry seasons (Chapter 3)

* Build response functions relating Loxahatchee River stage levels to soil moisture
and salinity (Chapter 3).














CHAPTER 2
CALIBRATION OF A COMBINED DIELECTRIC PROBE TO LOXAHATCHEE
RIVER FLOODPLAIN SOILS

Synopsis

A combined dielectric probe (Hydra Probe) measuring soil moisture, salinity and

temperature is evaluated for a wide range of soils (from mineral soils to organic muck)

present in the Loxahatchee River floodplains. The probe's advantage is that it responds

quickly to changing soil moisture, is easy to use in automated data collection systems and

is moderately priced (Mufioz-Carpena et al., 2005b). However, the relationship between

dielectric constant and soil moisture/ salinity significantly changes for high water content

and organic soils, of which little is known about the dielectric response.

To calibrate, samples of the three major soil series (Winder sand, Fluvent and Terra

Ceia muck) collected from the area were packed to field density and treated to a

combination of 25 different soil moisture and water salinity levels (5x5). The 4-electrode

probe took independent measurements of bulk electrical conductivity, pore water salinity

by a laboratory electrical conductivity meter (ranging from 0.01 10 S/m observed in the

area) and soil moisture was controlled by the Richard's plates and measured by

gravimetric methods. Voltage values from the combined dielectric probe were taken at

each combination of soil moisture and salinity. The calibration results for the sand were

similar to the manufacturer calibration, but the fluvent and muck soils resulted in an

entirely new and unique calibration. While calibration in the case of the sandy soil

increases the range of accuracy, without such calibrations meaningful measurements in

the fluvent and muck soils are not possible.









Introduction

The Hydra combined dielectric probe (Stevens Water Monitoring Systems, Inc.,

Beaverton, Oregon) is used in a variety of field projects to monitor soil moisture,

temperature and soil water salinity (e.g., US Department of the Interior Bureau of

Reclamation Pacific Northwest Region, Soil Climate Analysis Network of the Natural

Resource Conservation Service) (Stevens, 2006). The USDA has used its sensing

technology for over 10 years (Stevens, 2006), and NASA uses it to validate data obtained

from their Advanced Microwave Scanning Radiometer Earth Observing System

(Jackson and Cosh, 2003). This sensor can be used in a wide range of environmental

conditions including freezing soils and it responds quickly to changing soil moisture. It

works well with near surface positioning, is easy to use in automated data collection

systems and is moderately priced and accurate after calibration (Mufioz-Carpena et al.,

2005b). It also has potential for use in other projects, such as tracking saline

contaminants in the soil, i.e. nitrate under intensive horticultural systems (Mufioz-

Carpena et al., 2005b).

The probe determines soil moisture and bulk electrical conductivity by measuring

the soil dielectric properties (Campbell, 1990) based on three analog readings (0 2.5 V

DC). Dielectric permittivity (e) is directly related to the dielectrical constant, K, and the

permittivity of free space (eo) by the following equation:

e = K eo, where (2-1)

K = r is, (2-2)

K is a complex number composed of real (8r) and imaginary (e,) dielectric constants

(Campbell, 1990). Through calibration, real and imaginary dielectric constant can be

related to soil moisture (0) and bulk electrical conductivity (oa), respectively (Seyfried









and Murdock, 2004). With these known, the pore water salinity (ow) can be estimated

through additional calibration.

In the case of soil moisture, Topp et al. (1980) found a general model that relates

the 8, of granular mineral soils to soil moisture through a third order polynomial.

However, the largest source of uncertainty in measuring soil moisture and temperature

corrected soil pore water conductivity with this probe is from variation in response from

different soil types (Seyfried and Murdock, 2004). Topp's equation tends to

underestimate 0 in soils with high clay content (Dirksen and Dasberg, 1993) and highly

organic soils like peat (Shibchurn et al., 2005). It also performs poorly with volcanic

soils due to a greater portion of bounded water from their low bulk densities and large

surface areas (Regalado et al., 2003). However, the real dielectric constant measured by

the 50 Mhz Hydra probe is more sensitive to variations of soil type, particularly clay

content and clay type, than other probes that use a higher sampling frequency (Shibchurn

et al., 2005). In addition, results from other dielectric probes show that these soils require

special calibration (Shibchurn et al., 2005).

The Hydra probe was originally calibrated for the Hart sand, the Wilder silt and the

Ft. Edwards clay (Campbell, 1990). Since then, The Hydra probe has been calibrated for

measurement of soil moisture in the gravelly sand of the Dry Valleys region of Antarctica

(Wall et al., 2004), a very gravelly sandy loam comprised of mixed calcareous alluvium

from Arizona, and other various loams (Seyfried et al., 2004).

In the case of e,, Campbell et. al (1990) presented the relationship with the soil bulk

electrical conductivity (oa) where:

oa = (c*eo) E'. (2-3)









where S0 is the permittivity in free space with a value of 8.85x10-12 and co is the

angular frequency that for this probe is 5x107 Hz.

Due to the variability of this probe's response to different soil types, calibration is

necessary, especially for non-mineral soils. The Loxahatchee Floodplain project is an

ongoing effort that is attempting to set Minimum Flows and Levels (MFLs) for the

Loxahatchee River in southeast Florida (SFWMD, 2002) to protect the endangered

freshwater ecosystem of the area. Soil water conductivity and moisture data along the

floodplain where organic soils are present are needed to evaluate recent river flow

standards adopted in the area. The Hydra probe is being used to monitor salinity and soil

moisture along the floodplain where these hydric soils present a wide range of organic

matter content and textures that require a soil specific calibration.

The objective of this study was to calibrate the Hydra probe to a wide range of

organic and mineral soils specific to the Loxahatchee River Watershed. Soil moisture

and bulk electrical conductivity relationships vs. probe outputs (analog voltage readings

0-2.5V DC) were obtained for a combination of controlled moisture and salinity

conditions and then were related to pore water conductivity with various models

proposed in the literature.

Materials and Methods

Sampling and Soil Characterization

From May 18-24, 2004 a detailed soil survey was conducted to classify soils in the

Loxahatchee floodplain according to drainage class and series by the USDA-Natural

Resource Conservation Service (Kevin Sullivan, personal communication).

Two transects, perpendicular to the river, were chosen to be monitored. These

transects, Transect 1 and Transect 7, are representative of an unaffected freshwater







17


environment and an affected saline environment respectively. Monitoring these transects

will highlight differences in hydrological conditions between the two environments.

Figure 2-1 is a map showing the transect locations along the river. Figures 2-2 and 2-3

show the topography of Transects 1 and 7 respectively, as well at the location of the

Hydra probes.

Based on this characterization and the location of the Hydra probes in the



floodplain, the major types of soil being monitored that encompass a wide range of



inorganic-organic content were selected for calibration of the Hydra probe. The three

In late summer 2004, undisturbed and disturbed soil samples were taken from soil

near the location and depth that each Hydra probe was installed (see Figures 2-2 and 2-3).

These samples were used to calibrate the probes to the site-specific soil and obtain soil

moisture characteristic curves.

The samples were analyzed for porosity and bulk density (pb) using the core

method, and saturated hydraulic conductivity (Ks) using the constant head method (Klute,

1986). Specific density was calculated from bulk density results (ps). Residual (8O) and

saturated soil moisture (0s) values were also determined. The 8 for the fine sand is an

average of the lowest values found by the three probes because the water table dropped

significantly below each probe. This value was confirmed during the calibration

procedure, where the sand experienced up to 333 cm of pressure in the pressure extractor.

Since soil moisture in the fluvent and the muck never decreased to residual values, we

estimated 0, values based on soil survey values for this soil (USDA, 1981). for the

sand and the muck were calculated after determining bulk density of each and then

weighing a known volume of each after saturating them.

Equipment

Hydra probe

The Hydra probe is composed of a probe head, a multiconductor cable and four

probe sensing tines (see Figure 2-4). The probe head generates a 50 VMHz electrical

signal and the cable carries the 4 output DC data channel voltages (0 2.5 V DC) nd

provides 12VDC power. The four sensing (three outer and one center) tines form the

sensing volume (diameter 3 cm, length 5.7 cm) of soil from which electrical response is

measured.

C) Four probe sensing tines.

Four analog outputs are generated from the probe, three of the voltage values are

used to calculate the real (er) and imaginary (e,) dielectric constants using algorithms

provided by the manufacturer, which are then used to characterize the electrical response

of the soil. The fourth voltage is used to calculate soil temperature. The temperature

corrected (25 C o) real dielectric constant is used to calculate soil moisture, and the

temperature corrected (25 C o) imaginary constant is directly related to the bulk electrical

conductivity of the soil (aj). Soil pore water salinity (aw) is calculated by using oa and is

dependent on calculated soil moisture (0).

Four-electrode probe

The four-electrode (4e) probe method (Figure 2-5) was first developed by Wenner

(1915), and has been used to evaluate soil water content and salinity under field

conditions since 1931 (McCorkle, 1931). The 4e probe measures resistivity (inverse of

bulk conductivity) by passing an alternating current between the two outside electrodes.

The change in voltage (Ayp) is measured between the two inner electrodes. The ratio of

the voltage and current is used to determine electrical resistance (ER) (Gupta and Hanks,









1972), which can then be calibrated into the bulk conductivity of the soil sample

(Rhoades, 1976; Nadler and Frenkel, 1980). The following equation is used to calculate

bulk electrical conductivity:

ER = KAp/I (2-4)
Where K is the geometric coefficient related to the geometrical arrangement of the

probes and I is the electrical current used.

In this case, the following equation was used, where the distance between each

probe is the same:

K = 2nd, where (2-5)
d is the distance between the probes.
In order to measure conductivity, the probes can be arranged as necessary, but the

geometric coefficient will change accordingly. The Wenner arrangement indicates that

the distance between all of the 4 probes is the same. This calibration uses an arc

arrangement around a circle, where all probes are equidistant but at a slight angle to one

another. The bulk conductivity obtained by the circular four-electrode probe is

comparable to the original linear array salinity probes (Nadler et al., 1982).

These cells were made of PVC pipe with a height long enough to fit the combined

dielectric probe (5.26 cm diameter, 5.96 cm height, 129.51 cm3 volume). Eight bolts

were inserted into the side around the cell equidistant from each other (average distance =

1.64 cm) and protruding into the cell (Figure 2-5).

For calculating bulk electrical conductivity or oa, we used the average distance

between the bolts for each individual cell to decrease error as shown in Figure 2-5.

Pressure extractor

Pressure Extractors (see Figure 2-6) generally used to generate soil moisture curves

are used here to control the moisture level of the samples. Saturated soil samples are

placed in the extractor (pressure chamber) on ceramic plates and a known pressure is

applied, forcing the soil water through the pressure plate and out of the extractor.

Pressures of 0, 10, 50, 100, 150 and 33cm were applied to the Winder sand and pressures

of 0, 10, 20, 30 and 40 cm were applied to the Terra Ceia muck and fluvent. These

represent an equivalent draw-downs in water table observed at the experimental site of

the Loxahatchee River (Chapter 3). Pressures did not exceed the maximum pressure that

the plates could withstand. Plates with maximum bubbling pressures of 1000 cm and

5000 cm were used.

Calibration procedure

Sub-samples of each soil type were packed to field density into the cells described

above for measurement by the 4-electrode probe. A total of 180 cells were packed for

each of the three soil series, representing 5 pore water salinity levels (0.01, 0.1, 0.25, 0.5

and 1 S/m observed in the area), 4-5 soil moisture levels (0, 10, 50, 100, and 333 cm for

the sand and smaller increments ranging from 0 to 40 cm for the fluvent and muck) and 3

replicates for each soil moisture and salinity combination. Soil packed into cells used for

saturated soil measurements were re-used in the same cell for 10 cm suction

measurements after establishing the original conditions.

Once packed, the cells were soaked to saturate the soil and flushed with one of the

five NaCl solutions representing the 5 pore water conductivities specified above. At least

three pore volumes were used for flushing, until the drainage solution reached a constant

electrical conductivity value as measured with a handheld electrical conductivity probe

(AP50 pH/Ion/Conductivity Meter, Denver Instrument Company). Similar to the

procedure implemented by Nadler and Frankel (1983), it was assumed that once the

outflow had the same conductivity as the inflow, that the mobile pore water space, or soil

water had that conductivity. After saturation, the bottom of the soil cores were sealed

with parafilm paper (previously zeroed on the scale) and then weighed to determine

gravimetric soil moisture.

Eight resistivity measurements were taken around the core to determine bulk

conductivity (Figure 2-7) and voltage values from the combined dielectric probe were

taken (Figure 2-8). Water was extracted with pressure plate extractors at pre-selected

suction values (0 333 cm), after which the 4-electrode and the Hydra probe readings

were obtained. The samples were weighed after each measurement to obtain volumetric

soil moisture content. Three replicates were used for each moisture/salinity combination,

and measurements were repeated for each soil moisture level.

From the data acquired through the process above, a soil moisture characteristic

curve was obtained and the relationships between the Er vs. 0 and between si vs. bulk

electrical conductivity as measured by the 4e probe was determined. A polynomial

model similar to Topp's (1980) and a linear equation were used respectively.

We then found the relationship between 0, Ga (as measured by the 4-electrode

probe) and cw (as measured by the handheld EC meter) using several proposed models.

Four models for the relationship between Ga and cw were tested.

The first model, a linear model (Linear 1), was first proposed by Rhoades et al. in

1976

aa = OTw + a',, where (2-6)

T aO +b, (2-7)

and a and b are empirical constants. Therefore, for a fixed 0

aa = (a2 + b) aw + a', (2-8)

assumes a linear relationship between oa and ao and considers the tortuosity (T) of the

soil, which is expressed as a linear function of 0. o's represents the electrical conductivity

of the soil's solid phase, and in some soils, like coarse sand, can be as low as zero.

A second linear (Linear 2) model proposed for volcanic soils (Mufioz-Carpena et

al, 2005a),









a = (a02 + b) a + cO2 (2-9)

replaces the o's term from the linear model with a's depending on 02.

Rhoades et al. proposed (1989) a non-linear model for soils that do not exhibit a

linear relationship between oa and o- at a fixed 0 for low values of oa,

a = [0 -(cO +d)] a + ((0s, + cO +d) 2), 0 where (2-10)

where c and d are empirical constants and sol = pb/ps. Here, compared to Equation 2-7,

's, is not considered constant and the equation includes the effect of solute distribution in

the mobile pore water.

The last model is an empirical model derived from results obtained using

aggregated volcanic soils (Vogeler et al., 1996),

Ga = (cO d) ow+ (aO b), with cO > d and Ga> aO- b. (2-11)

Although this equation offers additional flexibility compared to the other three equations,

it lacks physical basis and increases the number of parameters needed (4 vs. 2 and 3 for

the previous models).

Results and Discussion

Soil Characterization

Tables 2-1 and 2-2 show soil descriptions for this fieldwork. Winder fine sand is

located at the higher ground at Transect 1 (see Figure 4), while the lower area that is

periodically flooded was characterized by Kevin Sullivan as a fluvent interbedded clay

and sand, with sand content increasing with depth (K. Sullivan, personal communication,

May, 2004). The Winder fine sand is poorly drained, nearly level soil and is found in

broad, low flats and depressions (USDA, 1978). Typically, the water table is within 25

cm of the surface for 2 to 6 months in a year. A fluvent is a stratified entisol whose

development is hindered by frequent flooding and deposition (Sumner, 2000).









Vegetation types are also provided in Tables 2-1 and 2-2 (Marion Hedgepeth, South

Florida Water Management District, personal communication).

The soil descriptions show that there are two major mineral soil series at Transect 1

(Winder fine sand and fluvent), and one major organic soil series that is being monitored

at Transect 7 (Terra Ceia muck).

Physical properties of the soils sampled are presented in Table 2-3. The samples of

the fluvent at Transect 1 have bulk density values of 0.65 (g/cm3) or less at soil depths

between 0-60 cm indicating the high organic content and unconsolidated nature. The









average of 2 samples taken from soils from 60 90 cm is 1.15, a bulk density more

typical of soil with higher mineral content and is closer in value to the upland Winder

sand. The hydraulic conductivity of the fluvent shows a wide range of values regardless

of depth. The higher average hydraulic conductivity values of the fluvent over the sand

may be due to the unconsolidated nature of the fluvent. As expected, the Winder sand

has low percent carbon values (organic matter), while the fluvent has values that almost

reach the definition of an organic soil, >12% organic carbon (Sumner, 2000). Testing for

cation exchange capacity is still in progress.

The soil encountered at Transect 7 is Terra Ceia muck (USDA, 1981). It typically

has a very low bulk density and hydraulic conductivity and is an organic soil as shown by

percent carbon results.

The fluvent and muck both have higher soil moisture values at each pressure step

than the sand. These soils were not exposed to pressure steps as high as the sand, at

higher pressure levels the muck and the fluvent shrink and volumetric soil measurements

are no longer possible. Also, when the soils lose contact with the wall of the 4e probe,

bulk electrical conductivity measurements are impossible. This does not present a

limitation to this study since in fact, the range tested is still similar to the range seen in

the field. Organic soils are known to shrink irreversibly when dried beyond some

threshold not normally experienced in natural conditions.

Soil Moisture Calibration

Figure 2-10 shows the relationship between the real dielectric constant and percent

soil moisture of the Hart sand that Campbell (1990) originally used to calibrate the Hydra

probe. It also shows the same relationship with the Winder Fine sand from the

Loxahatchee River floodplain. The point of greatest divergence between the two is at

high water content.

The difference in estimated soil moisture can be up to 7%. It is of interest to note

that the bulk density of the Hart sand is 1.66 g/cm3 (Campbell, 1990) while the Winder

sand has an average bulk density of 1.36 g/cm3. The range of measure real dielectric

constant for this soil is 3.95 25.88, with an average, 12.86.

goodness of fit of this relationship for each soil series. The manufacturer did not

calibrate the probe for similar soils, so these are unique calibration equations.

Soil Bulk Electrical Conductivity (ca) Calibration

The proposed calibration for determining the bulk conductivity of the soil is similar


to the manufacturer's calibration. Differences may be attributed to instrument


characteristics (constant). Figure 2-10 shows the direct relationship the imaginary


dielectric constant has with bulk conductivity as measured by the 4e probe for each soil

The sand results presented in Figure 2-12 confirm the values built into the program


provided by the manufacturer to process raw data from the probes. The muck and the


fluvent show a slight deviation from this relationship, which suggests that the high


organic matter content of these soils also has an influence on this relationship.


By comparing the slope of the relationship si vs. Ga for sand found on Figure 2-12


with Equation 2-3, we find that it is necessary to introduce a constant, k, that embodies


both the instrument characteristics and the soil series. This is a modification of Equation


2-3. The new equation becomes:


a =(ke* co eo) 8, (2-12)


Since permittivity in free space (so) is 8.85x10-12 and the angular frequency (co) is


=5x107 Hz, then it follows that kc =6.554 for the sand, and 4.52 for the fluvent and muck.

Although all four equations performed very well, they performed poorest for the

fluvent soil. The Vogeler empirical model performed best for all soil types (highest r2),

and the best performing of the physical based models for the sand and fluvent soils is the

non-linear model.

For the sand, the linear (Rhoades et al., 1976) model slightly over predicts ,a at low


Ga values. For the muck, the non-linear (Rhoades et al., 1989) slightly under predicts ,a at

all low Ga values and for most high Ga values. The Vogeler et al. (1996) equation fits best,

especially at low Ga values in all cases and will be selected for calibration of the field

values from the experimental site.

The Vogeler et al. (1996) equation was selected in the Loxahatchee River

monitoring project as it is the overall best fitting model.

Limitations

A major limitation to the calibration methodology is that it is better suited for

mineral soils. When organic or high clay soils experience dry they often shrink. This

prevents reliable measurements for volumetric soil moisture beyond a certain soil suction

(or equivalent water table drawdown. Fortunately, these soils in field conditions did not

experience the drawdown that causes this shrinkage, but it is not out of the realm of

possibility, and the experiment did not prepare the probe calibration for that situation.

Conclusions

A combined dielectric probe measuring real and imaginary components of the

dielectric constant, Sr and ei, was calibrated to three major soil series found in the

floodplains of the Northwest Fork of Loxahatchee River, the Winder sand, a fluvent and

the Terra Ceia muck. Sr and Ei were used to determine 0 and Ga respectively. So far, this

combined dielectric probe has rarely been calibrated to highly organic soils. This may be

due to its unique behavior, i.e. its high shrink/swell potential that makes it difficult to

work with in the lab. Unique relationships were found between Er and 0 for each of the

soils. Unique yet similar relationships were also found between si and Ga for each soil.

Four equations that relate 0, oG and Ga were tested to estimate Ga. All four equations

performed well, however the empirical Vogeler et al. (1996) equation performed best

across all three soil series. This may be a result of its additional flexibility due to an

additional equation parameter (4 against 2 or 3 for other equations). This calibration is

among the first attempts to characterize a group of soils representing a wide range of

organic matter content. These results show that the combined dielectric probe, in

conjunction with its unique calibration for each soil series and previously proposed

equations relating 0, ow, and Ga, can be used in the Loxahatchee floodplain soils as a






36


powerful tool to obtain two of the most important state variables in the management of

the baldcypress within the Loxahatchee floodplains: water content and solute

concentration.














CHAPTER 3
HYDROPERIOD AND SOIL WATER SALINITY IN THE BALD CYPRESS
FLOODPLAINS OF THE LOXAHATCHEE RIVER

Synopsis

The Northwest Fork of the Loxahatchee River is home to one of the last remnants

of native cypress river-swamp within the southern-most continental United States.

Vegetation studies conducted along the Loxahatchee River show that the highly valued

baldcypress have been retreating upstream since the turn of the century. It is believed

that the increasing salinity in the Loxahatchee River and the altered hydroperiod makes it

impossible for the baldcypress to thrive.

The goal of this study is to characterize soil moisture and salinity changes in the

floodplain during wet and dry seasons. Two floodplain transects perpendicular to the

river were monitored for one year. Twelve combined dielectric probes measuring soil

moisture, salinity and temperature were installed on each transect (3 depths x 4 distances

from the river) for one wet and dry season. Additional hydrological data was obtained

from the SFWMD on river flows and stages, local rainfall and local groundwater salinity

and elevation. Data obtained from the probes suggest that soil water salinities increase in

the surface soils (0-30 cm) of greater elevation and distance from the river during the end

of the dry season in the upstream freshwater transect. Soil water salinities stayed

relatively constantand low (below thegenerally accepted 2 ppt or 0.3125 S/m threshold

for baldcypress) in the flooded areas of this transect. Increase in soil water salinity in the

surface soil was concurrent with decreasing soil moisture. In the downstream transect,

which exhibits mangrove invasion, soil moisture remainedremains relatively constant.

37









Data suggest that pore water salinity varies based on river water salinity during the dry

season, although it is difficult to quantify,

as observed changes were subtle. Relationships found between hydrological data

and salinity show that minimum flows and levels adopted on the river for the protection

of the baldcypress maintain saturated conditions at the probe locations and low salinity in

the fluvent soil in Transect 1. During the study period, Transect 7 remained so saturated

that the conditions may have been responsible for any failure of baldcypress to germinate,

yet salinity remained below threshold values. Since this transect remained saturated

much of the study period, a longer monitoring period is necessary to study soil

moisture/salinity relations during drier times.



Introduction

The Loxahatchee River is located on east side of the lower peninsula of Florida

(26 59' N, 800 9' E), and its watershed drains approximately 210 square miles that lie

between Palm Beach and Martin counties. The Loxahatchee River has three main

tributaries: the North Fork, the Northwest Fork, and the Southwest Fork. These three

tributaries join at the Loxahatchee Estuary Central Embayment, which connects to the

Atlantic Ocean via Jupiter Inlet. The watershed includes protected areas such as Jonathan

Dickinson State Park, Loxahatchee Slough Preserve, Jupiter Ridge Natural Area and J.W.

Corbett Wildlife Management Area.

The Northwest Fork is historically a freshwater ecosystem and is home to one of

the last remnants of native cypress river-swamp within southeast Florida. Species

diversity is high here due to the overlapping of tropical and temperate vegetation

communities. Due to hydrological alteration in the watershed, the freshwater ecosystem











of the Northwest Fork is showing signs of stress and is receding. Vegetation studies

conducted along the Loxahatchee River show that the freshwater tolerant baldcypress

have been retreating upstream since the turn of the century. In 1855, the saltwater

tolerant mangroves were present only up to the confluence of the North, Northwest and

Southwest Forks of the River near the Jupiter Inlet, near river mile 6 (FDEP, 1855).

Figure 1 shows the vegetation changes in the floodplain from 1940 to 1995. In 1995, the

mangrove swamps were present up to river mile 10.4 and dominant between river miles

5.5 and 8.7. By 2002, mangroves represented over 75% of the plant community up to

river mile 9.2 (SFWMD, 2002). Baldcypress need freshwater conditions to thrive and

variation in hydroperiod to germinate and outcompete other plants.

Florida laws provide additional protection to the Loxahatchee River. Florida


requires water management districts to make a priority list and schedule for the


establishment of minimum flows and levels. Minimum Flows and Levels (MFL) are


designed to protect the ecology and water resources of a river from "temporary loss of


water resource functions which result from a change in surface or ground water


hydrology that takes more than two years to recover (Section 373.042(1) F.S.)." Chapter


373 protects water resource functions such as flood control, water quality, water supply


and storage, fish and wildlife protection, navigation and recreation. Current Northwest


Fork Loxahatchee River MFLs do not consider soil type, soil moisture or salinity


distribution within the floodplain.


A new MFL was proposed by the South Florida Water Management District


(SFMWD) in 2006 (SFWMD, 2006). A "Preferred Restoration Flow Scenario" was


chosen that allows for variable dry season flow between 50 and 110 cubic feet per second









(cfs) and requires the dry season mean of 69 cfs over Lainhart Dam. Also, flows are

augmented when flows are below 70 cfs between February and May, below 130 cfs

between August and November and 80 cfs for all other, transitional months. The plan

also requires augmented flows to downstream tributaries when the total flow of the river

is below 300 cfs (SFWMD, 2006). It is designed to allow enough flows to maintain

freshwater conditions in the VECs that require it and to prevent excessive drawdown.

The main objective of this study is to characterize soil moisture and salinity

changes in the floodplain during wet and dry seasons and buld response functions of

these variables vs. river flow values. This study will ultimately help the SFWMD to

evaluate recently adopted MFLs based on critical floodplain soil moisture and salinity

data.

Materials and Methods

Hydrological Data

Two floodplain transects perpendicular to the river, one impacted (Transect 7, river mile

9.1) and one non-impacted (Transect 1, river mile 14.8) were monitored for one wet and

dry season. Combined probes measuring soil moisture, salinity and temperature with

data loggers were installed on each transect at 4 locations and 3 depths (Figure 3-3 and 3-

4). The probes were programmed to take these three measurements every half hour.

Transect 1 has one well at the higher elevation portion of the transect (Figure 3-3).

Transect 7 has four wells. Three of the four wells are located near the soil moisture/

salinity probes (Figure 3-4).

determine the relationship between surface water and groundwater for the hydroperiod

analysis by combining it with the groundwater data.

The Loxahatchee watershed receives about 61 inches annually with a median value

of 57 inches. Total annual rainfall can range between 38 and 93 inches. Most of the

precipitation, about two thirds, occurs during the wet season, which is May through

October. The highest rainfall usually occurs in September at about 8.7 inches, and the

lowest rainfall occurs during December, January and February at 2.3 2.8 inches per

month (SFWMD, 2002). In south Florida, evapotranspiration accounts for about 45

inches of water loss per year (SFWMD, 2002). The SFWMD provides local rainfall data

and evapotranspiration estimates for future studies.

Soil Data

Undisturbed and disturbed soil samples were taken from soil near the location and

depth that soil moisture/ salinity probes were to be installed. The samples were analyzed

for bulk density (pb) using the core method and saturated hydraulic conductivity (Ks)

using the constant head method (Klute, 1986). The samples will also be used to calibrate

the probes to the site-specific soil and obtain soil moisture characteristic curves.

Monitoring Instruments

Soil moisture (0), salinity (o-) and temperature were continuously monitored by

combined dielectric probes (Hydra Probe, Stevens Water Monitoring Systems Inc., OR).

Figure 2 shows the placement of the probes for Transects 1 and 7 respectively. Each

cluster of 3 probes was connected to a field data logger (CR10 Campbell Scientific UT)

(Figure 3-5).

This type of sensor responds quickly to changing soil moisture. It works well with

near surface positioning, is easy to use in automated data collection systems, is

moderately priced, and is accurate after calibration (Mufioz-Carpena, 2004). However,

the relationship between dielectric constant and soil moisture/salinity significantly

changes for high water content and organic soils. Also, relatively low electrical

conductivity distorts data unless corrections are made, and the higher electrical

conductivity values distort soil moisture estimations to values lower than the actual value.

Since some soils in the Loxahatchee floodplain are organic, many have been

flooded for a majority of the monitoring period, and both high and low conductivity

values will be measured for both transects, it is essential to calibrate this probe. The

largest source of uncertainty in measuring temperature corrected soil water conductivity

is from variation in response from different soil types. Work to reduce the uncertainty









through calibration of the instrument with site-specific soils is currently under way in a

separate effort (Chapter 2).

To scale the field values for different soil series, soil moisture data will be reported

as effective soil moisture, on a range of 0 -1. Effective soil moisture is calculated by the

following equation:

Se=- 00 /0 Or (3-1)

where Or = residual soil moisture and = soil moisture at saturation.

Results and Discussion

Winder fine sand was found to be located at the higher ground at Transect 1, while

the lower area that is periodically flooded is a fluvent soil series characterized by

interbedded clay and sand, with sand content increasing with depth (K. Sullivan, personal

communication, May, 2004). A fluvent is a stratified entisol whose development is

hindered by frequent flooding and deposition (Sumner, 2000). The samples taken from

this horizon have very high variability due to its interbedded horizons. The soil

encountered at Transect 7 is Terra Ceia muck. Table 1 shows the range of soil

characteristics for each transect.

The 0r for the fine sand is an average of the lowest values found by the three probes

because the water table dropped significantly below each probe. This number is

supported by results from the calibration (Chapter 2). Since soil moisture in the fluvent

and the muck never decreased to residual values, we estimated ,r values based on soil


survey values for this soil (USDA 1981).

Figure 3-7. Hydrological and salinity values collected at Transect 7









Figure 3-6 shows local precipitation, and river flow at the Lainhart dam (near

Transect 1) during the monitoring period and effective soil moisture and soil pore water

salinity for the probe sets farthest and closest to the river. Figure 3-7 shows local rainfall,

stage at Transect 7 and effective soil moisture and salinity for the probe sets farthest and

closest to the river. Transect 7 is tidally influenced and flow values are not available.

Groundwater data (water table and groundwater salinity) are currently being processed by

the SFWMD.

The floodplains experience low rainfall from October through February and higher

rainfall in the spring through the summer. On September 25t, 2004 Hurricane Jeanne

passed through the study area. The rain from Hurricane Jeanne caused a major increase

in flow at Lainhart dam and stage at Transect 7 (Figures 3-6 and 3-7). Stage also

increased noticeably at Transect 7. Flow levels generally follow changes in rainfall

throughout the year at Transect 1. Stage at Transect 7 is affected by flow, but it is also

tidally influenced. Soil moisture at Probe 1 increases to saturation or near saturation on

June 30, 2005 to July 1, 2005 during times of rain, but there was not a significant increase

in the deeper probes in the probe set. The deeper soils were already near saturation at the

time. At Transect 1, soil moisture is influenced by rain and river stage height. At

Transect 1, there is an increase in soil salinity as the soil moisture decreases. This is

likely due to the concentration of salts as water evaporates rather than an input of saline

water.

To date, it is still difficult to obtain a complete picture of soil moisture and soil

water salinity response to hydrological conditions throughout both transects for the

monitoring period since probes 6 24 were installed later than probes 1 6, after most of

the winter dry season had past, and equipment difficulties caused lapses in data.










However, relationships can be discovered with what data are available. Table 3-2 shows

the range of soil moisture and soil water salinity throughout the monitoring period.

Probes 1 3 are located highest in elevation at Transect 1 and furthest from the

Northwest Fork (Figure 3-3). These probes experience the highest range in soil moisture,

and soil pore water salinity. The high soil moisture range at Probes 1 -3 is due to their

exposure to flooding and rain during the wet season and during the dry season, their

distance and difference in elevation from the river.

During the dry season, these probes have all reached zero effective saturation since

the water table is below the probes and the sand has low water holding capacity. Overall,

probes 10 12 have a lower range in moisture due to their proximity to the river. The

river has a higher influence on these probes. For probes 10 12, Probe 10 has the highest

soil moisture range compared with the other two probes that are the same distance from

the river; there is a corresponding high range of soil water salinity exhibited at probe 10.

Soil moisture values at probes 13 24 (Transect 7) have low standard deviations due to

their elevation since it is a relatively flat transect and all of the transect is exposed to

tides, so the soil moisture throughout the transect is influenced relatively equally by the

river height. These soils are saturated or close to saturated for most of the entire

observation period. At the probe location furthest from the river at Transect 1, the range

of salinity decreases, and the average yearly salinity decreases with depth. The shallower

probes experience greater salinity increases since they are influenced more by

evapotranspiration. The shallowest probe at the probe location closest to the river (Probe

10) also has a larger range in salinity than the deepest probe (Probe 12), but a slightly

lower average salinity.

Figure 3-9 shows that stage drops significantly as flow decreases which is confirmed by

our results comparing flow with soil moisture.









Figure 3-10 shows that the soil at the probe location furthest from the river, which

is also of the highest ground elevation, requires a higher flow in order to reach saturation.

Figure 3-10. Relationship between the flow rate at Lainhart Dam and effective soil
moisture in the baldcypress floodplain at different distances from the stream
and soil depths

The soil at the two probe locations closest to the river never desaturates during the

time period studied. At Transect 1, the baldcypress primarily live near the two probe

locations closest to the river, giving way to the types of vegetation (hammock) at further

and higher ground locations in the transect. According to these results, the current MFL

will allow for flows that keep the soil at the probe locations closest to the river saturated.

Note that the shallowest probes in the fluvent (both probe sets) are 0.25 meters below soil

surface. Figure 3-10 does not indicate when the soil surface is flooded. Baldcypress are

able to germinate when soils are moist but not flooded.

In general, good to fair results (<0.5 < R < 1) were obtained across distances and

depths. The fit may improve if factors such as antecedent rainfall, or microtopography is

considered in future studies. A graph created by the SFWMD (2005) helps to illustrate

this (Figure 3-8). Figure 3-8 shows the effect of microtopography on the flooded area.

The floodplain elevation is slightly lower at about 160 feet from the reference point

compared with the elevation at 290 feet from the reference point, the edge of the river.

This area (160 ft) becomes flooded before the soil closest to the river, which may explain

why the set of probes close to this depression record higher soil moisture values for the

same river flow levels as the set of probes closest to the river.









Time of rainfall may also be an important factor in the relationship between soil

moisture and river stage, particularly in the sand, which has very low water holding

capacity. For example, although river flow levels may be very high due to a previous

rainfall, the stage may not be high enough to saturate the soil at the probe locations in the

sand. Since sand has a very low water holding capacity, it may be quite dry even though

soil of lower elevation or higher water holding capacity is wet or saturated from previous

rainfall or high river flow levels.

Relationship between Flow and Pore Water Salinity at Transect 1

Salinity generally increases once the soil is desaturated, most likely from both

concentration of salts by evapotranspiration and low flow levels. However, even though

salinity increases during times of low soil moisture, pore water salinity remains low most

of the year and the when the salinity values did increase to above the 0.3125 S/m

baldcypress salinity threshold, the longest continuous time period where values remained

above the threshold was less than one week. No definitive pattern was observed relating

pore water salinity to river flow. This may be due in part because calculated (using

calibration equations explained in Chapter 2) pore water salinity values are dependant on

soil moisture, therefore any noise seen in Figure 3-10 will carry over into the relationship

between pore water salinity and flow. This means that the antecedent rainfall and

microtopography discussed above may also need to be considered for this relationship.

Relationship between Stage and Effective Soil Moisture at Transect 7

Stage at Transect 7 remains high enough relative to soil surface elevation that

almost continuous saturation of the soil is maintained. Even while salinity levels were

below salinity threshold values for the baldcypress, there is only a limited time that water

levels draw down enough to allow baldcypress seed germination if at all. The time









period that this transect was monitored was during a notoriously wet period with several

hurricanes and large storms passing through. The average elevation of the lower

floodplain is 0.46 m, while the average river stage for the monitoring period was 0.26 m.

This means that water levels in the floodplain remained very close to the surface. Lower

stages than observed during this time period may be needed in order to find a clearer

relationship between soil moisture and stage. Monitoring, particularly during the dry

season or drier years, should be continued to further this exploration.

Factors Associated with Salinity at Transect 7

At Transect 7, salinity increases at the surface probe furthest from the river during

a closely related increase in river salinity in early February 2005. This occurs at the

conclusion of a dry period and corresponding lower flows at Lainhart Dam. The salinity

in the river reaches salinity levels about twice that of the pore water salinity, which could

indicate the river as the source of the salinity rather than groundwater recharge. Also, the

peak of the river salinity is on Feb. 5 and the middle of the salinity peak for the shallow

probe is 20 days later, which may indicate a lag. Unfortunately, due to difficulties with

the field equipment, data from probes located closer to the river is not available. Perhaps

if we had this data, it would show a peak in salinity as well, but closer in time to the peak

of salinity at the river. This would confirm the above explanation for the behavior of the

changes in salinity. After this dramatic increase in river salinity, it returns to previous

levels and remains stable. Meanwhile, the pore water salinity at the probes closest to the

river decrease with time to levels closer to those found at the probes furthest from the

river. This decrease in salinity may indicate that, with increase water to the watershed,

freshwater is flushing out the floodplain and feeding the river, instead of during drier

periods when the river may be the water source to the floodplain. There may be a









seasonal variation as the source of the water in the floodplain (the river vs. watershed)

that affects the pore water salinity in the floodplain

The fact that we see salinity levels below the baldcypress salinity threshold during

the entire monitoring period may be due to the many rainfall events that maintain high

water levels. Monitoring during a drier period may show increases in salinity to values

higher than we see during this monitoring period. Figure 3-7 shows that the Loxahatchee

River may be a source of salinity to the floodplain during the end of the dry season.

During periods with even lower flows, we may see the same pattern but with salinity

peaks with higher values. Continued monitoring is suggested to explore the relationship

between river stage and pore water salinity.

Performance of the Instrumentation System

The methodology of the experiment required using a combined dielectric probe,

which was used with a datalogger consisting of an interface plate and the CR-10 CPU,

and a battery power supply. The field conditions were extreme, with extended flooding

conditions, a humid environment, thriving vegetation and fauna, tourist access and

natural disasters. Despite these difficult conditions, a large amount of reliable data was

collected. Each of the four were subject to failure at different times of the experiment.

Failure may have been caused by weather. For, example all probes at Transect 7 failed

between 11:00 and 11:30 pm on October 5th, the same time as when a large storm was

passing through. Unfortunately, the failure prevented us from collecting potentially

valuable data.

Conclusion

This study supports current research in best management practices of this nationally

valued ecosystem. Evaluating the hydroperiod and soil moisture salinity values in both









an unaffected and affected transect along the river shows characteristic differences in the

soil moisture and salinity of two different ecosystems, one freshwater baldcypress

swamp, the other in the transition zone between mangroves and baldcypress. Also, the

study shows the effect of soil type on the possibility of freshwater restoration.

Transect 1 represents the unaffected freshwater ecosystem. Here, shallow upland

soil experiences greater salinity, most likely from the concentration of salts as soil

moisture values decrease from evapotranspiration. The depressional areas experience a

smaller range in salinity and are saturated for most to all of the year. Soil moisture

relates closely with stage of the river and rainfall, and the values found at each probe

depend on distance from the river and elevation. The SFWMD can use the relationships

generated by the data to evaluate current minimum flows and levels for the Northwest

Fork of the Loxahatchee River. Since baldcypress health is dependent on freshwater

conditions and varying soil moisture throughout the year, this information is critical to

the regeneration of the baldcypress. The relationship of flow vs. soil moisture shows that

for the proposed MFL (dry season flow between 50 cfs and 110 cfs with a mean flow of

69 cfs over Lainhart Dam), the soil moisture at the probe locations in the fluvent at

Transect Iwill not change much and remain at saturation. The shallow sandy soil will

have effective soil moisture values close to zero. The MFL values will also maintain

salinity below the 2ppt (S/m) level established at this transect. Salinity also remained

below threshold values at Transect 7, and soil moisture values remained high. Since this

the transects were observed during relatively wet periods, and generally hydroperiod is

the driving factor for salinity values, it is necessary to continue monitoring to capture the

interannual variability of the hydroperiod and its subsequent effect on pore water salinity

in the floodplain.














CHAPTER 4
CONCLUSION

Through extensive work and collaboration, the SFWMD has collected much

information about the hydrodynamic and salinity changes of the Northwest Fork of the

Loxahatchee River. There is a solid understanding of the relationship between the flow

of the river from its many tributaries, its stage and the resultant salinity wedge. Detailed

vegetation data have been collected since 1940 that allows us an understanding of the

alarming vegetation changes over time, believed to be due to hydrological changes over

time, both natural and man-made. Long-term trends in salinity of the river have been

modeled to predict resultant vegetation types. This knowledge serves as a foundation for

the evaluation of restoration flow alternatives and the formulation of an MFL. However,

very little was known of the dynamics between the river and its floodplain. Effects of

soil type on restoration potential throughout the floodplain had not been studied. This

study addresses that paucity of understanding.

Soil moisture, temperature and salinity were measured at 4 locations and 3 depths

along two transects, each representing different ecological functions along the river- a

freshwater riverine wetland and a transitional, tidally-influenced transect with both

mangroves and baldcypress. The transects were monitored starting from September

2004, and data are still being collected at the time of publication. Data through March

2006 are presented in this paper. The combined dielectric probe measuring real and

imaginary components of the dielectric constant, Er and ei,, was used for monitoring and

was calibrated to the soils specific to the area to provide meaningful values. This probe









has many benefits including the ability to withstand the harsh environments found in the

floodplain, and calibration helps it overcome its obstacles. It was calibrated to three

major soil series found in the floodplains of the Northwest Fork of Loxahatchee River,

the Winder sand, a fluvent and the Terra Ceia muck. Er and ei were used to determine 0

and oa respectively. Unique relationships were found between er and 0 for each of the

soils. Unique yet similar relationships were also found between Ei and ,a for each soil.

Four equations that relate 0, ow and oa were tested to estimate oa. All four equations

performed well, however the empirical Vogeler et al. (1996) equation performed best

across all three soil series. This calibration is among the first attempts to characterize a

group of soils representing a wide range of organic matter content.

After monitoring and the calibration of the dielectric probe, we have a much better

understanding of the behavior of the floodplain soils in both of these transects.

Surprisingly, salinity reached higher levels at the unaffected site- in the higher elevation

sand that is the driest area of both transects. It is believed that salinity increase here is

from the concentration of salts due to evapotranspiration, whereas the variation in salinity

at Transect 7 is caused by thehydroperiod and salinity levels in the river. The probes

closest to the river at Transect 7 see a slight decrease in salinity over time after the wet

season starts while the probes furthest from the river see an increase in salinity at the end

of the dry season. This is only preliminary evidence suggesting that the relationship

between the elevation of the groundwater and the river changes seasonally. Obtaining

processed groundwater data will substantiate or refute this proposal. Overall, results

obtained from this study support the "Preferred Restoration Flow Scenario" and make it

more robust.











Future research. During the completion of this experiment, many questions were

raised as others were answered. Some suggestions for future work in order to expand

upon what has been built in this thesis document are as follows:

* Continue field data collection to better quantify soil moisture and soil
water salinity dynamics in the floodplain.

* Incorporate groundwater data into the general hydrologic analysis.

* Use observed data and fundamental principles to develop a robust numerical
simulation (Hydrus 2-D, others) with the ability to simulate long-term hydrological
and salinity changes for the entire floodplain.

* Derive physically-based functional relationships for soil moisture and soil water
salinity for integration into a management-based modeling tool, such as QND.

* Use these relationships and previous/ongoing vegetative research to build a
predictive model of ecosystem dynamics and hydrology-induced community
changes.
