摘　　要：The key point in the numerical simulation of breach growth and bed deformation process in dike burst is the accurate computation of flow and sediment transport. A numerical model for horizontal 2-D non-uniform sediment was developed to simulate the bed deformation process in the dike burst. The first-order scheme was used in computation. Several simulated results were worked out to demonstrate the applicability of the numerical model.The key point in the numerical simulation of breach growth and bed deformation process in dike burst is the accurate computation of flow and sediment transport.
