Abstract
The unstructured triangular mesh adapts to 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 caused the interface flux to achieve second-order precision. To verify the model established, this paper has simulated and calculated the two-dimensional curve course and some two-dimensional flow of dam-break separately, and obtained preferable results comparing with other methods.
