Validation and Recent Enhancement of a Three-Dimensional Curvilinear-Grid Finite-Difference Model for Estuarine, Coastal and Lake Circulation: CH3D

by Y. Peter Sheng, Univ of Florida, Ganiesville, United States,



Document Type: Proceeding Paper

Part of: Hydraulic Engineering

Abstract:

This paper describes the validation and recent enchancement of a three-dimensional curvilinear-grid hydrodynamic model: CH3D. The model employs finite-differences techniques and allows the use of confromal, orthogonal and non-orthogonal grids. A simplified second-order scheme previously used in a Cartesian-grid model (CELC3D and EHSM3D) is retained in CH3D. The paper first discusses some model validation tests with analytical solutions. Comparison of model results with field data obtained from Chesapeake Bay and James River are then presented. Recent efforts to model a moving shoreline and a moving front are briefly discussed.
