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. 关 键 词：DIKE BURST SCOURING numerical scheme FLOOD natural DISASTER
