Introduction:
The objectives of this investigation were to 1) review the literature and determine what
information was available regarding 50, 100 and 500 year return interval open coast storm surge
peak elevations and time history hydrographs and 2) based on this information recommend
which of these should be used by the FDOT for the ocean boundary condition for modeling
inland storm surge propagation in Florida’s coastal waters.
A number of Federal and State agencies have attempted to produce peak storm surge elevations
for various frequency hurricanes along the Florida coast. There have been far fewer published
hydrographs associated with these elevations. Most, if not all, of the computer models used in
analyzing storm surge start with the same basic governing equations. The difference between the
models lies in 1) the numerical schemes used to solve the equations, 2) the surge generation
mechanisms included in the analysis, 3) the boundary conditions imposed, 4) the types of storms
analyzed (real or synthetic), 5) the manner in which astronomical tides are treated (or not treated
as the case may be) and 6) the methods and procedures used to estimate the different return
interval events. With such a complex problem and so many different solution approaches taken
it should not come as a surprise that the results from the various agencies differ from each other,
in some cases significantly. Even though a number of papers and reports have been published on
these models and the procedures used, many of the details are missing and attempts to obtain
more information (through telephone calls and email) were, for the most part, not successful.
Each of the approaches have certain advantages and disadvantages. Some of the more recently
developed computer models are believed to do a better job in solving the governing equations as
a result of more accurate and efficient numerical schemes and methods. However, to date the
solutions using these models have not included one of the important storm surge generation
mechanisms, namely wave setup.
Design Storm Surge Elevations
This survey of existing storm surge information did not produce a clear cut best set of design
storm surge elevations. It then becomes somewhat subjective as to what values should be used
by the FDOT. The approach taken by the U.S. Army Corps of Engineers using the ADCIRC
model where actual storms were modeled using NOAA’s HURDAT data set is perhaps the best
1
approach of those covered in this survey. The problems with these results are that wave setup
was not included in the analysis and the grid along the Florida Coast is too coarse and does not
extend to the shoreline. These shortcomings have resulted in unreasonably low (or high)
predicted 50, 100 and 500 year return interval storm surge elevations as analyzed and reported in
the final report of the Pooled Fund Study (which uses the USACE model results).
While the approach taken by the Florida Department of Environmental Protection (FDEP) is less
appealing than that taken by the USACE it does include wave setup and produces more
reasonable elevations (reasonable as compared to water marks inside buildings from past
hurricanes). The problem here is that only the counties with sandy beaches (25 of the 34 coastal
counties) in Florida have been analyzed by FDEP. FDEP has published storm surge elevations
for 25 counties and 100 year storm surge hydrographs for 24 counties.
On the basis that FDEP has included all of the major generation mechanisms in their analyses
and that they have compared their results with near coast water marks in buildings where
possible, the FDEP storm surge heights for 50, 100 and 500 return interval hurricane storm
surges are recommended for use by FDOT at this time. For the counties not covered by FDEP
values have been interpolated from the surrounding counties using FEMA and NOAA results as
guides. The locations for each of the stations are shown in Figure 1 and listed in Tables 1.
Values of the 50, 100 and 500 year peak elevations are listed in Table 1. Plots of 50, 100 and
500 year peak elevations for the entire coastline of Florida are shown in Figures 2-4.
Design Storm Surge Hydrographs
There is very little published information on open coast storm surge hydrographs. NOAA
provided FDOT with hardcopy plots of category 5 storm surge hydrographs for locations along
the coast of Florida in the late 1980s. There is no record of how these hydrographs were
generated. The USACE has a synthetic hydrograph (mathematical expression of water height as
a function of time), the coefficients of which are related to the specific hurricane parameters
whose hydrograph is being represented. A Pooled Fund Study, with funding from Departments
of Transportation in several U.S. coastal states, modified the USACE hydrograph to make it
better fit the hydrographs produced by the USACE's ADCIRC generated data set in the areas
investigated in this study. It should be noted that the storm surges produced by this analysis did
not include wave setup and astronomical tide. This not only affected the heights of the surges
2
but the shapes of the hydrographs as well. The grid for the ADCIRC model used to generate the
data set analyzed in the Pooled Fund Study is relatively coarse and the nearshore bathymetry in
the model is not as accurate as perhaps it should be (according to the engineers at USACE that
configured and ran the model and generated the data set used by the Pooled Fund Study). The
combinations of coarse grid, less accurate nearshore bathymetry and the exclusion of wave setup
most likely accounts for some of the unreasonably low (or high) values reported in the Pooled
Fund Study Reports.
For the counties evaluated (and reevaluated) in recent years by FDEP, 100 year return interval
hydrographs have been published as part of the report. These hydrographs are the ones (of the
approximately 600 synthetic storms run at each location) that achieved a peak height at the coast
near the 100 year return interval prediction. Note that the combination of parameters that
produced the hurricane that achieved this elevation is not unique. That is, other combinations
could achieve the same elevation and thus the hydrograph shape is not unique.
The hydrograph shape, as well as its peak height, is important in establishing accurate peak flow
velocities and peak water elevations at bridge crossings within coastal waterways subject to
storm surges.
Another important factor for which little information exists is the lateral extent of the surge on
the open coast. This is particularly important in situations where tidal inlets are in close
proximity or where the coastal land masses are sufficiently low that overtopping occurs during
the storm event.
Again, since the FDEP included of all of the important storm surge generation mechanisms in
their analysis, their results are used as the basis for the hydrographs recommended for use by
FDOT. For those counties not covered by FDEP an interpolation scheme was used to provide
design hydrographs for these locations. The 100 year hydrograph published by FDEP along with
extrapolated hydrographs with 50 and 500 year return interval peak elevations are presented for
each of the FDEP sites along the Florida coast. Interpolated hydrographs are presented for the
10 counties not covered (or published) by FDEP.

The locations for each of the stations are shown in Figure 1 and listed in Table 1. Plots of the
recommended hydrographs are shown in Figures 5-20. Electronic files with hydrographs with
50, 100 and 500 year return interval peak elevations are included on the attached CD in ASCII
format.
The attached dataset contains two additional hydrographs with a 100 year return interval peak
elevation for each location. The three hydrographs have different rates of rise and fall and
durations. The additional hydrographs can be used to examine the impact of increased rates of
rise and fall and different duration storms on the flow parameters at the point of interest provided
time and resources allow such an analysis.
