Abstract:

The Three-Dimensional Numerical Model of Hydrodynamics and Sediment Transport in Lakes and Estuaries (SED3D) simulates the flow and sediment transport in lakes, estuaries, harbors, and costal waters. SED3D is a dynamic modeling system that can be used to simulate the flow and sediment transport in various water bodies under the forcing of winds, tides, freshwater inflows, and density gradients with the influence of the Coriolis acceleration, complex bathymetry, and shoreline geometry. This model can be run in a three-dimensional mode, a two- dimensional vertically integrated 'x-y' mode, or a two-dimensional 'x-z' mode. Given proper boundary and initial conditions, the model can compute the time-dependent, three-dimensional velocity components (u,v,w), temperature (T), salinity (S), and suspended sediment concentration (c) in the Cartesian and vertically stretched grid system (x,y,s). The model contains a free-surface, as opposed to a rigid-lid, with proper boundary conditions for velocity, temperature, salinity, and sediment. A simplified second-order closure model of turbulent transport is used to compute the vertical eddy viscosity and diffusivity contained in the model equations.
