| Abstract: | Based on the discretion of linear kinematic-wave equation by the finite difference method and the concept of numerical dispersion a method is developed to model the physical dispersion. The Muskingum-Cunge routing model and the routing model with a prediction duration are developed in this paper. The models have been applied to the flood routing for a practical channel, and good results are obtained. |
