A numerical model was developed for the Mobile Bay system to investigate the impacts associated with certain system alterations. The Adaptive Hydraulics (AdH) Code was used to validate the numerical model for hydrodynamics and transport. Due to the physics based nature of the AdH numerical model, the validated model could be altered to represent the plan conditions (removal of the Mobile Bay Causeway). Comparisons of the base and plan model results indicate the impacts of removing the causeway are not widespread and are primarily limited to Chocolatta Bay and the areas adjacent to the causeway. The model results suggest an increased exchange of water between Chocolatta Bay (north of the causeway) and Mobile Bay for the removed causeway configuration. Chocolatta Bay also experiences an increased inflow from the river systems which result in increased suspended sediment concentrations and sediment deposition.
