This scheme uses smooth wave instead of discontinuouswave, so the wave in time field is continuous phase and has good frequency spectrum characteristics.
The numerical results agree with those of available literatures and show that the method is robust and stable for getting the discontinuous solutions of the shallow water wave equation.
计算结果与已有文献结果基本一致,证明该方法有效、稳定,能够模拟浅水长波方程中的间断解问题。
