Modeling Hurricane Waves and Storm Surge using Integrated Tightly Coupled Scalable Computations

In the wake of recent Gulf of Mexico hurricanes (Katrina, Rita, Gustav and Ike), efforts to accurately model storm surge in the Gulf of Mexico have intensified. A modeling system has been developed that simulates hurricane winds, wind-waves, storm surge, tides and river flow in this complex region. This is accomplished by defining a domain and computational resolution appropriate for the relevant processes, specifying realistic boundary conditions, and implementing accurate, robust, and highly parallel unstructured grid algorithms for both the wind waves and the long wave current/storm surge/tide model.
