Abstract:

This report documents a numerical investigation of Mississippi Sound and adjacent areas. A model of the complete Gulf of Mexico is employed to develop tidal constituent boundary conditions for the two-dimensional vertically integrated Waterways Implicit Flooding Model which was extended to include salinity. In order to calibrate and verify the extended model WIFM-SAL, an intensive data collection program was conducted. Data were analyzed for tidal constituents. A global grid representing Mississippi Sound and adjacent areas was constructed to interface with the GTM grid. Bottom friction mechanics were calibrated on this global grid. A hypothetical regional dredge disposal plan was considered on the global grid by increasing the size of Sand Island. A refined grid was constructed around the Pascagoula Channel in order to study alternative channel configuration effects on Mississippi Sound. Horizontal salinity conditions were also investigated. Wind speed and direction were specified as meteorological inputs. Originator supplied keywords include Dredge disposal Finite difference Harmonic analysis Hydrodynamics Navigation channels Numerical modeling Salinity transport Tidal constituents.
