Three Dimensional Hydrodynamic Model for Stratified Flows in Lakes and Estuaries211 (HYDRO3D): Theory, User Guidance, and Applications for Superfund and Ecological 211 Risk Assessments

摘要

The HYDRO3D program has been documented to aid in the simulation of lakes,211u001eharbors, coastal areas, and estuaries. HYDRO3D is a dynamic modeling system that 211u001ecan be used to simulate currents in water bodies as they respond to tides, winds, 211u001edensity gradients, river flows, and basin geometry and bathymetry. The code is a 211u001ethree-dimensional, time-dependent, o-stretched coordinate, free surface model 211u001ethat can be run in fully three-dimensional (3-D) mode, tow-dimensional vertically-211u001eaveraged (x-y), and two-dimensional laterally-averaged x-z mode. The applications 211u001eprovided demonstrated that the model is capable of realistic simulation of flow 211u001eand salinity transport in complex and dynamic water bodies. These applications 211u001einclude simulations of tidal circulation and salinity transport in Suisun Bay, 211u001eCalifornia and Charlotte Harbor, Florida and wind-forced circulation in Green 211u001eBay, Lake Michigan. Tidal circulation in Prince William Sound, Alaska was 211u001einvestigated to determine the feasibility of applying the model under emergency 211u001econditions. Finally, the calibration of the model for the Mississippi Sound is 211u001eillustrated.
