AN EFFICIENT COUPLED 2-DH AND 3-D HYDRODYNAMIC MODEL FOR RIVER AND COASTAL APPLICATIONS

摘要

In this paper the numerical method for a 3-D hydrodynamic model has been outlined. The numerical scheme is mainly based on 2-DV numerical techniques and is implicit, non-iterative and unconditionally stable. A coupled 2DH-3D system has been developed to provide the possibility of positioning the 3-D area in within part of a much larger 2-DH domain and then solving the hydrodynamic part of these areas simultaneously. Therefore, nc external boundary data are needed to be included for the 3-D model area.
