Design Hurricane Storm Surge Pilot Study


Scope of Service:
The design storm event for most of Florida's coastal waters is produced by hurricane generated storm surge. Computer models that compute the propagation of storm surge from the open coast through the tidal inlets and over the low lying barrier islands into the bays, waterways and streams require the appropriate storm surge hydrograph as the ocean boundary condition. A recent study by Dr. Sheppard at the University of Florida showed there are substantial differences in various state and federal agencies. This study also showed that there is very little information on the shape and spatial attenuation of hurricane generated storm surge hydrographs. There is a need for 1) more accurate design storm surge elevations, 2) design storm surge hydrographs, and 3) spatial attenuation of these surges along the coast. Fundamental to obtaining improved design storm surge hydrographs are questions regarding 1) the coupling of storm surge and wave models and 2) the effect of tidal inlets and the adjoining bays on the open coast storm surge in the vicinity of the inlet.
