Abstract

This paper presents a two-dimensional (2D) finite volume model that simulates sediment transport in overland and channel flow simultaneously. The model is based on the solutions of 2D shallow water equations coupled with the Exner equation. The bed load transport rate is calculated as an exponential function of depth-averaged flow velocity. To formulate a Godunov-type cell-centered finite volume method, the 2D domain is discretized using Cartesian cells. The HLL approximate Riemann solver is adopted, and a linear reconstruction is implemented to obtain values of conservative variables at cell edges. The model is applied to the 1D and 2D test cases. The model can satisfactorily reproduce the measured hydrographs and bed profiles for both dry bed and wet bed situations.
