CHARACTERISTICS OF THE SEASONAL HIGH WATER LINE
CHANGE ALONG THE SANDY BEACHES OF THE STATE
OF FLORIDA: AN ATLAS


I. INTRODUCTION
This report presents the results of an analysis of the Seasonal High Water Line (SHWL)
position database computed from the beach profile data surveyed by the Office of Beaches
and Coastal Systems (OBCS) of the Florida Department of Environmental Protection (FDEP)
over a period extending from the 1970's to the 1999's. Although the shoreline positions are
based on the location of the Mean High Water (MHW), the reference elevation used by
OBCS of the FDEP for some regulatory purposes is the so-called Seasonal High Water
(SHW) elevation, which is defined as an elevation of 1.5 times the mean tidal range above
the MHW elevation. The rationale for considering SHW elevation rather than the MHW
elevation is that the SHW elevation is higher than MHW elevation resulting in the SHW
position being located further inland than the MHW location on a beach profile, such that the
changes in SHW positions would correspond more to the long term shoreline change rate and
less to the individual storms and seasonal fluctuations. A graph of the SHW elevation for the
24 coastal counties of Florida is presented in Figure 1.

The beach profile data are available for locations spaced approximately 1000 feet apart along
the shorelines of the 24 coastal counties of the predominantly sandy beaches of the State of
Florida. Data from approximately 3624 FDEP monuments corresponding to about 805 miles
are analyzed and the results of the analysis presented in formats useful to a regulator, to a
prospective homebuyer, to a real estate agent, to an engineer or scientist. The analysis
methods used for this report are similar to those presented in the report,
"CHARACTERISTICS OF SHORELINE CHANGE ALONG THE SANDY BEACHES OF
THE STATE OF FLORIDA: AN ATLAS". Sample results are described in the following
sections.


II. DESCRIPTION OF THE SEASONAL HIGH WATER LINE POSITION DATABASE

As noted above, the analyzed results presented in this report are based on the multiple beach
profiles surveyed in the field by the OBCS of the FDEP. This program of surveying beach
and offshore profiles was initiated when the Coastal Construction Control Line (CCCL)
program (known as Setback Line program then) was established by the Florida Legislature in
1971. Beach and offshore profiles were surveyed on a county-by-county basis for the
establishment or re-establishment of the CCCL on a county-by-county basis; however the
regulatory mission of the OBCS of the FDEP has been redefined and expanded since then.
As a result, OBCS surveys beach and offshore profiles wherever or whenever it is warranted
to do so; for example, in a beach area of the shoreline where critical beach erosion is
indicated or before and after a storm event in a selected study area, etc. As a consequence,

East and the West Coasts of Florida.

the number of beach profiles available for a location can vary considerably for the analysis of
SHWL data.

A physical marker embedded in the ground is used as a reference location to survey the
beach profiles; both the horizontal and the vertical controls of the top surface of the physical
marker are established relative to the Florida State Plane Coordinates and NGVD of 1929,
respectively. This physical marker is also referred to as a monument that has a unique
monument identification label in the county. The original FDEP monuments are generally
located behind the dune systems for the protection of the monuments against physical
disturbances and each of these FDEP monuments are placed approximately 1000 feet apart
alongshore wherever physically possible; it should be noted however that there are some
locations along the beach in some of the 24 coastal counties where it was extremely difficult
to locate the monuments 1000 feet apart so that, in such cases the distances between the
monuments can be somewhat more or less than the 1000 feet. The cross-sectional beach
profiles are surveyed from at least behind the primary dune systems to at least the wading
depth of 5 feet at a profile survey azimuth that is established in the first survey at the










monument, such that the survey azimuth is approximately perpendicular to the local
shoreline. The positions of these monuments are depicted in a county-by-county series of
CCCL aerial photographs prepared by OBCS for the 24 predominantly sandy beach counties,
consisting of twelve counties on the east coast of Florida, six counties on the west Panhandle
coast of Florida and six counties on the lower west coast of Florida. See Figure 2 for a map
of Florida with the number of monuments indicated for each of the 24 coastal counties for
which the SHWL change characteristics are analyzed.

The number of times the SHWL positions that are computed for each monument range from
2 to 14 for the profiles surveyed between 1971 and 1999 by OBCS. Table 1 presents the
range in years between which field surveyed beach profiles were acquired for each of the 24
coastal counties in Florida by OBCS. Figures 3a, 3b and 3c show survey dates available for
each monument for the 24 coastal counties in Florida. It should be noted that the period for
which surveys are available is also a period during which considerable beach nourishment
has occurred at some localities. Thus, at these localities, the SHWL characteristics will
include the nourishment effects.

Figure 4 presents a typical set of SHWL position data. As has been noted above, the survey
profile line along which the SHWL intercept is computed, is oriented approximately
perpendicular to the beach and the SHWL position is referenced to the monument. In this
example, the station is monument R-023 in Nassau County, the most northerly county on the
east coast of Florida, and it is seen that there are 6 surveys available, with the earliest
computed from the 1974 beach profile survey and the latest computed from the 1998 beach
profile survey. There are two features of the data in Figure 4 that are significant to the results
to be presented in this report. First it is seen that an advancing trend of SHWL change is
evident. This trend is represented by a straight line that will be described in the next section.
Secondly, there is significant variability about the trend line. Both the trend line of the data

and the deviation of the data about the trend line are relevant to the OBCS regulatory
responsibilities and to a general understanding of shoreline dynamics. The Seasonal High
Water Elevation at monument R-023 in Nassau County is 11.89 feet as shown in Figure 5.
There are several possible explanations for the trend of SHWL positions and also for the
fluctuations about this trend. The purpose here is to quantify the trend and variability of the
SHWL changes and not to provide detailed discussions of their causes or interpretations;
however, it is noted that storms can cause fluctuations as can seasonal effects and the trend
can be due to natural causes (sea level rise, onshore/offshore sediment transport, etc), human
related effects (jetties, channels, beach nourishment, etc) and errors in the data. The shoreline
at monument R-023 in Nassau County has been nourished. The following section describes
the analysis procedures applied to the data.


III. ANALYSIS PROCEDURES

Time Periods Analyzed

The beach profiles available for the 24 coastal counties of Florida from OBCS of FDEP
spans a period from 1971 to 1999 in contrast to the MHWL position database which
encompasses a period from mid-1800's to the 1990's for which the long-term and the
short-term historical shoreline change characteristics study have been developed recently.
The beach profile data are available for a maximum period of 28 years from which to
compute the SHWL position change characteristics. The purpose of the analysis of the
short-term data is to provide results, which may be more representative of the current
trends although they may also correspond to the long-term historical shoreline change
rates. As has been referred to earlier, Table 1 presents the data periods analyzed for each
of the 24 counties.

MSWL and MLWL Relative to NGVD.

Analysis Methods and Description of Results

First, the SHW elevations for each monument location in the 24 coastal counties are
computed, where SHW elevation is computed as elevation of 1.5 times the mean tidal
range above the MHW elevation. As shown in Figure 1, the SHW elevation varies from
12.0 feet at the north end of Nassau County to 5.04 feet at the south end of Dade County
for the east coast of Florida, from 4.41 feet at the north end of Pinellas County to 5.18
feet at the south end of Collier County, and from 3.08 feet at the west end of Escambia
County to 5.11 feet at the east end of Franklin County. Tidal data provided by OBCS
staff are used to compute the SHW elevations for the 24 coastal counties of Florida. Next,
the SHWL intercept position is determined for each of the beach profiles at each of the
monuments and for each survey in the 24 coastal counties of Florida. There are some
beach profiles for which the SHWL intercept positions cannot be determined because the
SHW elevations to be used for those beach profiles are higher than all of the beach
profile elevations. The availability of multiple beach profiles surveyed for a given
monument provides for the computation of the multiple SHWL intercept positions in the
form of distances relative to the monument versus survey dates. These results represent
the database used for the analysis of the SHWL change characteristics. For the time
period analyzed, the trend and a measure of the variability around the trend line are
determined.

Determination of SHWL Trend Formally, the trend line extracted from the data
available at each monument is the best least squares fit to the available data within the
period of time being analyzed. Referring to Figure 4, the shoreline trend is represented by
a solid line for all of the data and represents a SHWL advancement (accretion) of 4.6 feet
per year for this location. This result is based on all six data points available at this
monument. At least two data points are necessary to carry out the method of least squares
and there are some monuments in some of the 24 coastal counties where this criterion is
not met even though there may be more than two beach profiles surveyed. One case, for









example, is when the SHW elevation is higher than the surveyed beach profile elevations
so there is no SHWL intercept position to be determined for the monument; another case
is that, although the SHWL database consists of SHWL data computed from recent field
surveyed beach profiles, that is more reliable than the historical shoreline change
database, there is still a filter to remove "unreasonable" data points, such as, data points
that are outside three standard deviations relative to the trend line using all the SHWL
positions for the monument. These data are discarded. Thus it is possible if enough data
points are removed, the total number of data points remaining could fall below the
minimum two required to carry out the computation. The reason for this filter is to avoid
computing unreasonable short-term trend lines that are inconsistent with the results
computed for the neighboring monuments. The number of removed data points is less
than 8.5% considering all the data for the 24 coastal counties.

Quantification of SHWL Variability About the Trend Line -The determination of the
SHWL variability can be illustrated by referring to Figure 4. For each time at which data are
available, the deviation from the data to the trend line is calculated. The variability is the
root-mean-square of all the deviations within the time period for which the data are being
analyzed. The deviations are a measure of the uncertainties to be expected in the projection
of the trend lines in the future. As noted previously, in addition to actual SHWL positions
being determined from the beach profiles, the fluctuations could still include some unknown
contribution due to errors in the data. A minimum of three data points is required for the
determination of the variability, i.e. one standard deviation about the trend line. Thus, in the
tabulations to be described, if the two or the three data points required to compute the trend
line and the variability respectively are not met, then no results are provided for that
monument.


IV. RESULTS

The results are presented on a county-by-county basis in both graphical and tabular forms.
Figure 6 presents the graphical results of the analysis from 1974 to 1999 for Nassau County,
which are representative of the short-term SHWL change trend. The solid SHWL trend line
is provided adjacent to the shoreline map of the county on which the monuments are shown.
The solid vertical bars through the SHWL trend line represents the magnitude of the
deviations described earlier; the equidistant lengths of the bar about the SHWL trend line
position correspond to one standard deviation. The deviations are also plotted as dashed lines
on the same graph. Note the different vertical axes and the different scales used in the graph
when examining the plots, especially when comparing one graph to another. Table 2 presents
sample pages of the tabulations provided for Nassau County. The first column is the
monument identification for the county; the second column is the SHWL change rate; the
third column is the variability or one standard deviation and the fourth column is the number
of SHWL data points available that were used in developing the results for the previous two
columns. Selecting Monument R-23 (which can be seen by referring to Figure 6 to be located
approximately 2.5 miles south of the Entrance to St. Mary's River), the SHWL rate of change
is 4.6 feet per year. The deviation about the trend line is 12.9 feet. These results are based on
all 6 data points. At this location, there has been beach nourishment during the 1974-1999











period encompassed. Again, the purpose here is to describe the characteristics of the SHWL
change and not to interpret the results.


Tables 3a and 3b are summary tables of the average SHWL change characteristics on a
county-by-county basis for the 24 coastal counties, which include the average short term
shoreline (MHWL) change rates based only on all the field surveyed beach profiles acquired
by OBCS.

East Coast -Computing the average of all the SHWL change rate data and the average of all
the MHWL change rate data between Nassau and Brevard counties, the computed average
SHWL change rate of +1.37 feet per year is higher than that for the computed average
MHWL change rate of +0.74 feet per year. Similarly using all the SHWL and MHWL
change rate data for counties between Indian River and Dade, although the average SHWL
change rate of +0.78 feet per year is higher than that of the average MHWL of +0.69 feet per
year, the difference between them (average SHWL and average MHWL) is much less. Also
the change rate averages computed using Nassau-Brevard Counties' data are higher than that
computed using Indian River-Dade counties' data. On the other hand, the average of all the
MHWL variability data between Nassau to Brevard counties of 25.40 feet is higher than that
for the SHWL of 20.35 feet, and considering the variability data between Indian River and
Dade counties, it is about the same in magnitude for the average SHWL variability and
MHWL variability which is 18.19 feet and 19.22 feet respectively.

West Panhandle Coast Computing the average of all the SHWL change rate data and the
average of all the MHWL change rate data between Escambia and Franklin counties, the
computed average SHWL of +3.02 feet per year annual change rate is less than that for the
MHWL change rate of +3.38 feet per year. The average of all the MHWL variability data
between Escambia and Franklin counties is 35.03 feet that is about the same in magnitude as
that computed for the average SHWL variability of 36.04 feet.








West Coast For the shoreline between Pinellas and Collier Counties, the average SHWL
change rate of +2.88 feet per year is less than that for the MHWL change rate of +3.41 feet
per year. The average of all the MHWL variability data between Escambia and Franklin
counties is about the same in magnitude as that computed for the average SHWL variability
of 29.18 feet and 31.56 feet respectively.

The averages using all the SHWL data for the 24 coastal counties are: average SHWL change
rate is +2.06 feet per year, the average SHWL variability is 26.52 feet, the average MHWL
change rate is +2.09 feet per year and the average MHWL variability is 28.17 feet, based on
the analysis of all the available field surveyed beach profiles from 1971 to 1999 from OBCS.

In reviewing the results presented in this Atlas of SHWL change characteristics, it is
surprising at least from the short term analysis of data that the Florida SHWL is not
characterized by a pervasive erosional trend. However, it will also become evident that the
Florida SHWL is characterized by some areas of erosion and other areas of advancement
and, as noted, substantial nourishment has occurred during the period encompassed by the
data used in this analysis. Stabilized inlet entrances play a great role in these uneven patterns
of erosion and accretion. The problems caused by inlets are especially severe on Florida's
east coast and at a smaller number of west coast inlets. It is also surprising that the
variabilities of the MHWL and SHWL are so close in magnitude.

V. DESCRIPTION OF THE TABLES

The Appendix presents results for each of the 24 CCCL counties for which shoreline
positions are available. The first page for each county is a summary of the total shoreline
length, the total number of original monuments in the county, (not necessarily the total
number of monuments for which SHWL data are available in the particular county) and the
total period encompassed by the data. Also included on this page in tabular form are the
county average SHWL change rate, the county average deviation and the county average
SHW elevation. The second page is a figure depicting the county shoreline, the locations of
the monuments on the shoreline and the characteristics of SHWL change as described earlier.
Adjacent to each shoreline is a graph that presents the SHWL change rates for each of the
monuments. A vertical bar, which extend equidistant on either side of the trend line depicting
the SHWL change rate, represents the magnitude of one standard deviation, described earlier.
In addition, the standard deviation is also plotted as a dashed line. Note that the vertical
scales are different for the SHWL change rate and the SHWL standard deviations plotted on
the graph and are not necessarily the same from one county to the next. In some plots
extreme data points cause the overall scales to vary greatly so the scales for these plots with
these extreme data points have been adjusted.

The remainder of the pages for a particular county in the Appendix present detailed
tabulations of the short-term SHWL change characteristics. The header information is the
county name with the range of dates for which the SHWL data are available. The first
column is the monument identification, the second is the annual SHWL change rate, the third
column is one standard deviation from the trend line and the fourth column is the number of
points that are available for the analysis. Finally, if the number of SHWL positions available








was too small (<3) to calculate the standard deviation or too small (<2) to calculate SHWL
change rate at a monument, this information is missing from the figures and tables for the
monument.

VI. AN APPLICATION OF THE SHWL DATABASE

The standard deviation data in Column 3 of Table 2 represent the total standard deviation as
defined in "High Frequency Shoreline Changes for the Panhandle area of Florida" Dean
(1999) for each monument. The equation for the anticipated recession, RTR ,
RTR = FTRA,
in which 6 is the total standard deviation about the trend line as presented in the Appendix
and the factor, FTR, is presented in Table 4 for various return periods.

The predicted SHWL recessions for the high frequency return periods in Table 4 are
computed as an illustration of the application of the recommended method from the report
above under certain assumptions stated in the report. For monument R-023 in Nassau
County, the "total standard deviation" is 12.9 feet, for which the recession, RTR values are
computed for each associated return period and the results are both tabulated and plotted in
Table 5 and Figure 7, respectively. The values of FTR in Table 4 are based on a normal
probability distribution function.

VII. FINAL COMMENT REGARDING USE OF THIS ATLAS

The user of the results presented in this Atlas is cautioned that they represent the results of
the analysis described and that there are other methods by which the data could have been
analyzed. Although it is believed that these alternate methods would not lead to results that
would have differed greatly from those presented here, in cases where the characteristics of
SHWL change are of considerable importance, it is recommended that the user examine the
original sources of data for determining the SHWL position data for the locations of interest.
