User's Guide for a Three-Dimensional Numerical Hydrodynamic, Salinity, andTemperature Model of Chesapeake Bay

摘要

A time-varying three dimensional (3D) numerical hydrodynamic model of ChesapeakeBay has been developed to provide flow fields to a 3D water quality model of the bay. The water surface, 3D velocity field, salinity, and temperature are computed. Major physical processes affecting bay circulation and vertical mixing are modeled. A particular feature of the model is the solution of transformed equations on a boundary-fitted grid in the horizontal plane. This user's guide presents a detailed discussion of theoretical aspects of the 3D model (e.g., basic equations, boundary conditions, turbulence closure, etc.), followed by a discussion of the organization of the computer code and input data requirements. Listings of portions of the various input data files for an application that simulates the hydrodynamics of the Chesapeake Bay during September 1983 are also provided.
