DescriptionHurricane Michael made landfall near Mexico Beach, FL on October 10 as
a Category 5 storm. Measurements of peak water levels revealed storm
surge as high as to 4.37 m (NAVD88). Areas surrounding Mexico Beach,
Port St. Joe, St. George Island, and Apalachicola experienced
wide-spread flooding and extensive damage. To gain an understanding of
storm surge and related overland flooding, we simulate the water level
and wave response from Hurricane Michael using a tightly-coupled
ADCIRC+SWAN model of the northern Gulf of Mexico (NGOM), NGOM3. The
ADCIRC (Advanced Circulation) code computes water levels and
depth-averaged currents via the shallow water equations while SWAN
(Simulating Waves Nearshore) computes relative frequency and direction
of wind-waves from the action balance equation. Both models utilize
the same NGOM3 unstructured finite element mesh (5.5 million nodes)
that spans the western north Atlantic Ocean, Caribbean Sea, and Gulf
of Mexico and includes detailed representation of the Mississippi,
Alabama, and Florida panhandle coastal floodplain. Model resolution
ranges from 20 m – 200 m across the overland regions and describes the
significant hydraulic features such as bay/inlet systems, sounds,
estuaries, coastal river, and the Gulf Intracoastal Waterway that can
convey or inhibit storm surge flows. The NGOM3 model is a result of
over a decade of effort and improvements. A custom visualization
system is used to visualize a variety of parameters including
wave height, water surface elevation, wind, and current.
