Numerical simulation of bed deformation in dike burst

摘要

The key point in the numerical simulation of breach growth and bed deformation process in a 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. Sev- eral simulated results were worked out to demonstrate the ap- plicability of the numerical model.
