摘要：

A three-dimensional numerical model was developed in the present paper,with the goal of simulating suspended sediment transport in discontinuous situations.In the model,the advection-diffusion equation of suspended sediment was solved using the compact discontinuous Galerkin(CDG)method based on unstructured meshes.The evaluation of the model revealed good agreement between the proposed model and existing theories.The model has second-order accuracy.Moreover,the model was applied to an idealized case of suspended sediment transport caused by rip currents based on the field spatial scale.
