Numerical simulation of flood wave when concrete dam break

Abstract

    Dam break flow often causes huge damage. The hypothesis of total or partial concrete dam break shown in official reports is considered as fundamental documents in study the flow due to dam collapsed. The article indicates a numerical method which is used to solve the shallow water equations to simulate shock wave due to dam break. Besides that, the paper also gives some test cases to verify the effectiveness and robustness of the numerical scheme in shock capturing capacity. In the last part, the author applied this scheme in studying the influence of different geometry sharps of reservoirs on the breach hydrographs. A real case study in Italy is selected to demonstrate this research.
