| Abstract: | The basic characteristics of the shallow water equations and the difficulties for solving them were analyzed.The key techniques for solving large-scale discontinuous shallow water flows were reviewed,including the main computational schemes,the "well-balanced" method between pressure terms and source terms due to bottom topography in the conservative shallow water equations and the modeling technique of moving boundaries under discontinuous shallow water flows. |

| Keywords: | discontinuous shallow water flow numerical simulation computational scheme source term due to bottom topography moving boundary |
