| Abstract: | A 2D vertical finite volume model of tidal flow and sediment transport is established by laterally integrating Navier-Stokes equation. The orthogonal curvilinear grid is used, and actual topographic forms are generalized by jam technology of mesh, numerical equations is discreted using finite volume method, coupled equations of pressure force and velocity is solved by SIMPLER numerical modality. |
