Application of One Finite Volume Method in Dam-break Simulation

摘要：

The unstructured triangular mesh is suitable for complex irregular boundary. Based on this, adopting finite volume method to disperse shallow water equation and combining with the finite difference method, this paper has developed a new discrete format that could cause the interface flux to reach second-order precision. Through simulating and calculating typical example, this format can not also well measure the wave advance of dam-break wave but also has strong ability of simulating gap. Furthermore, it can get satisfactory results in simulating the discontinuous shape and location of flood wave of dam-break.
