Abstract:Two 1D nonlinear hyperbolic conservation equations are derived by decoupling and splitting the 2D shallow water equations and solved by using the hybrid TVD scheme with flux limiters. And the propagation, reflection and diffraction of dam break waves induced by the sudden and full destruction of a dam are numerically simulated. The complex flow characteristics of the bores are demonstrated, which provides scientific basis for the analysis and prevention of disaster caused by dam destruction.
Keywords:shallow water equations  difference splitting  TVD scheme  dam break waves  refection  diffraction.
