3. Modeling Selected Storms Offshore: TAOS and HURWAVE

The main wave threats to the lee side of Dominica are from two hurricane-related sources. First, there are wind driven waves riding atop storm surge during and after passage of the eye of a hurricane. Second, there are swells from hurricanes which have passed the island.

Four characteristic storms were abstracted from the historical record, as modeled by HURSTAT, above. Each storm event is described with pressure, wind speed, and the general wave characteristics in deep water. These deepwater wave characteristics were output by TAOS and HURWAVE and were used, in turn, as inputs for the WES spectral model of near-shore waves.
