16. Abstract

This report summarizes the first year of a five-year monitoring study of the physical and environmental parameters associated with the 1989/90 Perdido Key, Florida, beach nourishment project. Dredging of Pensacola Pass for the U.S. Navy has provided a large
quantity (approximately 4.3 million m3) of beach-quality sand which has been placed on the Gulf of Mexico shore of Perdido Key. The nourished beach lies within the Gulf Islands National Seashore, under jurisdiction of the National Park Service.

Topographic and hydrographic surveys were conducted before and after placement of the nourishment material; surveys will continue over the remaining four years of the study. Numerous sand samples were collected throughout the study area during both surveys to
investigate the spatial variation of sediment size. A wave gage, providing time histories of wave height; direction, and period, was installed offshore of the Perdido Key Ranger
Station. Tidal stage, and the direction and magnitude of any mean currents are also available from the wave gage instrumentation. A digital weather station at the Perdido
Key Ranger Station provides wind speed and direction, air temperature, rainfall rate, and wetness data. A tide gage on Santa Rosa Island provides additional tide data. Color photographs were taken during each survey.

This report presents all data collected through December 9, 1990, with the exception
of beach profile and sediment grain size data. The reader is referred to previous reports for items not addressed here (Work et al., 1990a, 1990b, 1991).

PERDIDO KEY BEACH NOURISHMENT PROJECT:
GULF ISLANDS NATIONAL SEASHORE 1990 Annual Report


1 INTRODUCTION


This report summarizes the first year of a five-year monitoring study of the physical and environmental parameters associated with the 1989/90 Perdido Key, Florida, beach nourishment project. Dredging of Pensacola Pass for the U.S. Navy has provided a large quantity (approximately 4.3 million m3) of beach-quality sand which has been placed on the Gulf of Mexico shore of Perdido Key (Figure 1). The nourished beach lies within the Gulf Islands National Seashore, under jurisdiction of the National Park Service.

The primary objective of the physical monitoring study is to provide a quantitative description of the beach: its shape, volume, and composition; and to investigate how these properties vary with time in response to the beach nourishment project. Topographic and hydrographic surveys were conducted before and after placement of the nourishment material; surveys will continue over the remaining four years of the study. Numerous sand samples were collected throughout the study area during both surveys to investigate the spatial variation of sediment size.

Several other environmental parameters are being monitored as a part of the study. Many of these will assist in the development and improvement of tools for future coastal engineering applications. A wave gage, providing time histories of wave height, direction, and period, was installed offshore of the Perdido Key Ranger Station. Tidal stage, and the direction and magnitude of any mean currents are also available from the wave gage instrumentation. A digital weather station at the Perdido Key Ranger Station provides wind speed and direction, air temperature, rainfall rate, and wetness data. A tide gage on Santa Rosa Island provides additional tide data. Color photographs were taken during each survey.

The completed beach nourishment project spans approximately 8 km. The eastern limit of the nourished area is near Florida Department of Natural Resources (DNR) survey monument R-64; the western boundary is near R-41. Figure 2 shows the extent of the nourished area and the locations of data collection stations. Table 1 provides a chronology of all work done to date as part of the physical monitoring study.

This report presents all data collected through December 9, 1990, with the exception of beach profile and sediment grain size data. The reader is referred to previous reports for items not addressed here (Work et al., 1990a, 1990b, 1991). All data are available on floppy disks, readable on IBM PC-compatible computers; readers desiring data should contact the authors to have their name placed on a mailing list. Mailings will then be conducted periodically as new data become available. Photos are also available.

An ongoing task is the assimilation of a long-term data set for a historical study of Perdido Key. The historical report will make use of available topographic and hydrographic survey data, geological and oceanographical studies, and documentation of storms and the impact of man on the area.


2 DATA COLLECTION

2.1 Topographic and Hydrographic Surveys

Prior to commencement of the beach nourishment project, twenty-five beach profile survey lines were designated, encompassing and extending beyond the project domain. Each profile passes through an onshore survey monument (a brass disk mounted in a sunken concrete post) and runs approximately perpendicular to the local shoreline. The profiles are separated by a nominal distance of 600 m (2000 ft), with a 300 m (1000 ft) spacing used near each end of the nourishment area. Several profiles were added during the postnourishment survey to provide finer detail near the western end of the nourished beach. The additional profiles were surveyed only to wading depth, and were located at monuments R25, R-29, R-35, R-37, R-39, and R-41. Table 2 provides the coordinates of each DNR survey monument within the survey area. Note that not all of these monuments were used.

Each profile extends out into the Gulf of Mexico until the distance from shore exceeds 800 m, or the depth exceeds 8 m. For the pre-nourishment survey, profiles 36 through 61 were also extended to the north, toward the intracoastal waterway, to the -2 m contour.

The same equipment and techniques were used for both the pre- and post-nourishment surveys. A transit equipped with a magnetic compass was first used to establish the direction of the survey line, which was marked by a wooden stake. Portions of the profile above the

-2 m contour were surveyed by standard rod-and-level methods. An optical level was set up near the profile of interest and adjusted so that the operator viewed through it in a horizontal plane. The rod was placed on a point of known elevation (the survey monument) and a reading taken, establishing the height of the level. The rod was then placed at points along the profile where the ground slope changed, and readings were taken. Distances along the profile were measured by a fiberglass tape. It is estimated that the elevations measured in this manner are accurate to the nearest centimeter, and horizontal distance measurements to the nearest decimeter. The crewmember holding the rod (or "rodman") maintained his alignment along the profile visually. The rodman continued out to approximately the -2 m contour. Where distances from shore to the point of interest exceeded 50 m, an optical rangefinder was used to measure horizontal distances.

An 8 m survey vessel was used to measure the deeper portions of the profile. The boat was equipped with an acoustic fathometer, a Mini-Ranger Falcon 484 rangefinder, and a computer to record the signals from the fathometer and Mini-Ranger. The fathometer emits a signal directed toward the seafloor and measures the time required for the signal to return, allowing computation of the depth of water beneath the boat. The fathometer is calibrated by placing a flat object beneath it at a known depth and adjusting the output until it agrees with the known correct value. The assumption implicit in this method is that there is little variation in water density throughout the water column; this is not thought to be a problem at the site of interest here. The fathometer used has an accuracy of 3 cm over the range of depths encountered during the surveys at Perdido Key.


7









The principle underlying the operation of the Mini-Ranger is the same as that of the fathometer, substituting electromagnetic waves for sound waves. The onboard "master" unit sends a signal to the shore-based "slave" unit and measures the time required for a response. Errors associated with this method are estimated to be less than 2 m.

The boat operator maintained alignment along the profile visually with the assistance of a pair of large, orange range boards. Speed was typically between 4 and 6 knots. Each profile was traversed three times, so that the three runs could be averaged to remove the effects of any wave action. The depths reported by the fathometer require correction for the tidal stage at the time of measurement, so a simple stilling well was installed in the surf zone near the Perdido Key Ranger Station. Readings were taken visually every fifteen to thirty minutes during the hydrographic survey.



2.2 Sediment Samples

Sand samples were collected along each profile during both surveys at the following elevations: dune, berm, beachface, -1 m, -2 m, -5 m, and -8 m/End of line. The prenourishment survey also included collection of samples on the bay side of the island at the beachface, -1 m, and -2 m positions. (Future work will also include samples collected mid-way across the new beach). Tables 3 and 4 illustrate the spatial coverage of the sand samples.

The onshore and the -1 and -2 m samples were collected by scooping a small quantity (200-300 g) from the upper 5 cm of the beach and placing it in a small cloth sack. Offshore samples were collected by boat. A portable Loran unit was used to determine the location of each sampling point, and a heavy iron sampling bucket was lowered to the bottom and dragged until it had filled with a sufficient quantity of sediment. It was then hauled to the surface and a sample taken. The Loran coordinates of each offshore sampling point are given in Table 5. Note that most of the "8 m" samples were actually taken from a lesser depth; if the boat had travelled 800 m from shore without reaching the -8 m contour, a sample was taken from the end of the survey line.

To determine whether any fine material might be lost as the sediment sampling bucket was hauled from the bottom to the surface, additional samples were collected at five locations by a diver. The diver sampled the bottom using a coffee can, placed a lid over the opening, and swam to the surface. Figure 3 presents a comparison of two samples collected at the same location by the bucket and diver techniques. The differences in the grain size distributions are less than the margin of error associated with the analysis, justifying use of the bucket sampling method.



2.3 Wave/Current/Tide Data

A directional wave gage was installed offshore of the Gulf Islands National Seashore Ranger Station on Perdido Key in approximately 7 m of water on January 18, 1990. The gage measures the time-varying pressure and horizontal velocity components, storing the data on a magnetic tape. This allows computation of significant wave height, H,, representative wave period, T,,, wave direction, magnitude and direction of any mean current, and tidal stage. The gage does not record continuously, but collects 15-minute bursts of data every six hours. The data analysis procedures are described in Work et al. (1990b).

The wave gage is self-contained, and must be retrieved to allow access to the data. The original package was replaced May 2, 1990, the second unit August 8, 1990, and the third December 6, 1990. The fourth unit, currently in place, should be replaced in early 1991 by a gage that will be hard-wired to shore, allowing more convenient access to, and checking of, the data.

This report includes data collected by the wave gage (Appendices I and II) covering the period January 18, 1990, through December 6, 1990. Gaps in the data set indicate either gage malfunctions or periods when magnetic storage was exhausted prior to recovery of the package.

2.4 Meteorological Data


A mechanical (analog) weather station was in place at the Perdido Key Ranger Station from January 29, 1990, through June 24, 1990. This unit recorded a continuous time history of wind speed, direction, and air temperature on a strip chart. The strip charts were digitized to provide daily average values.

The mechanical weather station was replaced by a digital unit June 24, 1990. The digital weather station records wind speed, wind direction, air temperature, rainfall, and wetness data once per hour. A computer at the University of Georgia is accessed once per day to transfer the data.

A data set from the National Weather Service's Pensacola weather station (300 28' N, 870 12' W; elevation 34 m) was obtained for comparison to the Perdido Key data set. Figures 4 and 5 compare daily average wind speeds, directions, and air temperatures for the Pensacola station and the Perdido Key analog weather station for April, 1990. Agreement is seen to be quite good, in part because of the smoothing associated with using daily average values.

Figure 6 compares data from Pensacola (available at three-hour intervals) with that from the Perdido Key digital weather station (hourly data), for the first half of July, 1990. Agreement is reasonable, but the Perdido Key station appears to overpredict the high temperatures.

Data for the period January 29, 1990, through December 9, 1990, are presented in Appendix III. No data are available for the month of March.



2.5 Additional Tide Data

A tide gage was installed on the Ft. Pickens fishing pier on Santa Rosa Island on January 30, 1990. The gage mechanically records a trace on a strip chart, providing a time-history of the still water level (i.e. neglecting the effects of short period waves). Fresh paper must be installed weekly; the National Park Service has assumed responsibility for this task. Data

from the gage are presented in Appendix IV. Several large, temporal gaps are evident, due to both lack of maintenance of the gage and mechanical problems.



2.6 Photographic Documentation

Color slides were taken during the post-nourishment survey to visually document the effects of the beach nourishment project. Shots were taken along each survey line, typically illustrating the views to the east, south and west. Color prints were made from the slides and mounted in photo albums. The photos are not presented in this report; all photographic material is being held by the Coastal and Oceanographic Engineering Department of the University of Florida in Gainesville, FL.




3 PRESENTATION OF DATA


The beach profile and sediment data are discussed briefly below; all other data are presented in appendices.

3.1 Beach Profile Data

Figure 7 presents an example of the pre- and post-nourishment beach profiles for Range 44. Note that the horizontal axis denotes distance from the survey monument in meters, with positive distances indicating points seaward (i.e. towards the Gulf of Mexico) of the monument. The vertical axis indicates elevation in meters relative to NGVD (National Geodetic Vertical Datum of 1929). The pre-nourishment survey is plotted with a heavy line; the light line corresponds to the post-nourishment survey.

It can be seen in Figure 7 that the beach nourishment project increased the dry beach width at Range 44 by approximately 150 m. This profile is of particular interest because of the large "bumps" that appear offshore. These features were present in each of the three passes across the profile, and are also evident, to a smaller degree, along several other profiles within the nourished area. Inspection of the spatial variation of the D5o sediment

size (see Figures 9 through 12) reveals that these bumps correlate well with locations of fine sediment. A number of the offshore sand samples from the vicinity of Range 44 resembled a fine ooze when brought to the surface. They became cemented upon drying and had to be crushed before sieve analysis. Presence of this fine material is not solely a result of the dredging project, however, since several of the pre-nourishment samples exhibited the same properties. It does appear that the dredging has increased the amount of fine material at the 5 m depth, however.

Figures 8a and 8b illustrate the change in dry beach width and cross-sectional area, respectively, along Perdido Key due to the beach nourishment project. To estimate the volume change between two sections, the cross-sectional areas are averaged and multiplied by the distance between sections. Computing volume changes between each pair of adjacent sections and summing all changes gives the project volume, 4.3 million m3 for this case. This estimate includes only changes between Ranges 42 and 64, the extent of the nourished area.



3.2 Sediment Data

All sediment samples were analyzed by drying and sifting through a series of sieves. For each sample, the mean and median grain sizes, sorting index, skewness, and kurtosis were computed. The analysis procedure is described and parameters are presented for each sample in Work et al. (1991).

Figures 9 through 12a illustrate the longshore variation in D50 sediment size for each depth, before and after beach nourishment. Figure 12b shows the cross-shore variation, after averaging all samples corresponding to like depths.

Figures 12b and 13 and Table 6 present the average distribution of sediment size on Perdido Key. Figure 13 was developed by computing the sediment size distribution curve for each sample and then averaging all curves corresponding to like depths. The values reported in Table 6 are the D50 sediment size for each curve shown in the figures.
