Evolution of a Three-Dimensional Curvilinear-Grid Hydrodynamic Model for Estuaries, Lakes and Coastal Waters: CH3D

Traditional finite-difference models of estuarine, coastal and lake hydrodynamics and transport use rectangular Cartesian grids in the horizontal directions. In order to accurately represent the complex geometries in estuaries, lakes, and coastal waters, very fine grid resolution is often required. This paper reviews the development and evolution of a generalized curvilinear-grid (or 'boundary-fitted grid') hydrodynamic model for estuaries, lakes and coastal waters: CH3D. Model applications to James River, Chesapeake Bay, and Lake Okeechobee are discussed. A brief review of several generic model features is also given.
