摘要
利用ＴＶＤ差分格式设计思想，给出了一种数值求解浅水波方程的数值方法。经过数值解与精确解的比较，表明该方法能很好地模拟溃坝洪水波间断面的位置和形状。进一步对溃坝洪水长波与地面障碍物的作用进行数值模拟，得到了合理的结果。
A numerical method is presented for solving the shallow water equation with TVD scheme. Comparison of the numerical solution with analytic solution shows that the method can well specity situation and shape of discontinuous surface. Further, numerical simulating studies about the interaction of a dam breaking long wave with an obstacle have also been done with reasonable results.
