Abstract

This paper presents a 2D numerical model for the simulation of bed elevation change in a curved channel. The model uses the Streamline Upwind/Petrov-Galerkin finite element method and Bubnov- Galerkin method for the numerical solution of the shallow water equations and the Exner's equation, respectively. The developed model is applied to two laboratory experiments: 180? curved channel and 140? curved channel experiments. The simulation results indicate that the numerical model predicts successfully sediment deposition and erosion near the inner and outer banks, respectively. It is also found that bed elevation profile computed by the developed model agree well with the measured data.
