Horizontal 2-D Uneven Sediment Mathematical Model in Dike Burst

摘要: 基于一阶迎风格式平面二维河道溃口水流模拟,建立了非均匀沙模型并用于模拟平面二维溃堤水流泥沙及河床变形。给出了实际算例,证明该模型计算速度快,精度高,符合水流泥沙运动基本规律。

Abstract: Based on the first order upwind scheme,the paper establishes a set of horizontal 2-D uneven sedinvent mathematical model in dike burst.Several simulated results are given to introduce the applicability of the numerical model.
