| Abstract: | In this paper,we apply the finite volume method based on KFVS scheme to solve the control equations of two-dimensional shallow water,and build a model which can simulate the instantaneous form of two-dimensional water flow whne the dam broken.Finally,we use this model to simulate the process of two-dimensional flood routing in the two cases.One is an asymmetric dam breaking,another is a symmetric dam breaking which there is an impediment in the left lower position of the dam.The simulating results indicate this metod is very efficient in simulating the movement of two-dimensional shallow water. |
