Abstract
Virginia Institute of Marine Science (VIMS) has been developing a general purpose three-dimensional hydrodynamic and sediment transport model, Environmental Fluid Dynamics Computer Code (EFDC; Hamrick 1992). The real-time model simulates density and topographically-induced circulation as well as tidal and wind-driven flows, and spatial and temporal distributions of salinity, temperature and sediment concentration. The model also is capable of handling the wetting and drying of shallow area, hydraulic control structures, vegetation resistance for wetlands and Lagrangian particle tracking. The information of physical transport processes, both advective and diffusive, simulated by the hydrodynamic model can be used to account for the transport of passive substances including non-conservative water quality parameters. A water quality model with twenty-one state variables has been developed and integrated with EFDC to form a three-dimensional Hydrodynamic-Eutrophication Model (HEM-3D) of the VIMS.
