摘要：
In this study, a two-dimensional hybrid numerical model for sediment transport based on lattice Boltzmann method and finite difference method is presented. The governing equations for water flow and suspended sediment transport are the shallow water equations and the advection-diffusion equations, respectively. Sediment load is also involved, so that riverbed deformation is numerically simulated. The model is verified by testing transportation of bank-slump sediment in a sharp bended channel with the comparison to the results of well-accepted finite volume method, illustrating the effectiveness of the proposed hybrid model.
