Abstract

A finite element FE model is used to study tides and hurricane storm surge in the Gulf of Mexico in the region ranging from the Mississippi Sound to the northwest coast of Florida. Issues that are emphasized include the use of large domains, the importance of a high degree of grid resolution in coastal regions of interest, the use of meshes with highly varying nodal densities to minimize the size of the discrete problem, and the use of the generalized wavecontinuity equation GWCE for FEbased solutions to the shallowwater equations. The computations presented are unprecedented in their scope, level of localized detail, and degree of gridsize variability. The GWCEbased FE model leads to very accurate and efficient flow solutions.
