简介：such type of scheme is extnded to the 2D shallow water equations. A finite volume method on arbitrary quadrilateral elements is presented to solve shallow water flow problems with complex boundaries and having discontinuities.,A high-resolution finite volume numerical method for solving the shallow water equations is developed in this paper. In order to extend finite difference TVD scheme to finite volume method,Fig. 3(a) Water surface elevation for a rectangular dam-break Fig. 3(b) Contour of surface elevation for a rectangular dam-break
