產生水波首先要有波源，設置不同的波源便可以得到不同的水流情形，我們用兩種方法來產生波源：一種是通過設置邊界條件和初始條件產生，這種方法用於模擬潰壩波的反射、折射等現象；另一種是通過擾動控制產生，這種方法用於模擬雨滴、瀑布、船波等自然現象。本論文的第一部分我們討論了目前水動畫模擬常用的幾種方法；在第二部分討論了我們所使用的兩類數值方法：有限差分方法和有限體積方法；在第三部分我們模擬了雨滴、船波、潰壩波等一些水流現象。For example, after the collapse of ditong dam in idaho, may 5, 1976, it was found that it was not impervious very well, the impervious curtain was built poorly. when the seepage went through the impervious curtain, the exit water from the pervious material of the downstream or the right side of dam through the foundation or certain line between the foundation and the dam caused contact scour and piping
如美國愛得華州提堂壩於1976年5月5日潰決，事後調查分析，因壩基透水性大，防滲帷幕施工質量差，滲流穿透帷幕，經地基或地基與壩的接觸面從壩體下游側透水料區逸出或從右壩肩繞滲經下游壩體逸出，出逸的水流引起了接觸沖刷和管涌，導致潰壩。On the basis of the result of the research on the landslide damming of river, failure of landslide dam, outburst flood and landslide surge, the failure of the part of landslide will arise a maximum surge height to 6m at the dam site, at the same time, the height of landslide dam will reach possibly 33m, and the flood peak of outburst flood will reach 15841 ~ 7613m3 / s, and make water level to rise at 11 ~ 4m through jinjiang to xiluodu of the jinsha river

有限體積方法能夠處理具有不規則邊界水域的水流現象，在本文中，我們把求解的水域離散成無結構三角形網格，對潰壩問題、雨景等水流現象進行了模擬，和有限差分方法一樣，我們僅僅指定產生水流動畫的波源，水流動畫的細節均由數值方法產生，不需要人工的干預。Four major failure modes for high arch dams, namely destabilization dam lost stability failure, shearing - slipping failure, excess cracking and man - caused destruction, are presented by means of failure tree analysis
