| Abstract | ||||
| The objective of this study is to develop a vertically integrated two dimensional numerical sediment transport model. This model is divided in two parts: hydrodynamic modeling and sediment transport modeling. Hydrodynamic modeling simulates flow velocities which are then used in the sediment transport model to simulate sediment concentrations. To represent the sediment transport system in a flow, the conservative form of two dimensional advection diffusion equation is used. To solve this equation a fractional step method, also known as standard split approach (Sobey 1983, Dragsolav 2001), is used. This approach splits the advection diffusion equation in two parts: advection and diffusion, which are solved separately. To solve the advection part, a high resolution conservative algorithm for advection in incompressible flow developed by Leveque (1996) is used. To solve the diffusion part, a semi-implicit finite difference scheme is used. | ||||
