摘要
本文研究溃坝问题的数学模型,探讨了有限差分法和谱方法用于计算,提出了改进意见,数值模拟表明结果是令人满意和符合物理特性的。
In this paper, the mathematical model of the break dam is discussed. The application of finite difference method and pseudospectral method to shallow water equations is described. This numerical method seems very useful and successful. It is shown that the numerical result is satisfying and it demonstrates the principal characteristics of observations.
