| Abstract: | Based on all|transformed depth|averaged differential equation and SCM|method, this paper established a mathematical model for analyzing the complex watercourses which have channel bends,flood|plain and bridge piers. This model would be used to analyze how constructions influence the fluid|state and sediment transportation. With computation and model test of a channel accrossed by a freeway bridge, the reliability of theorical results is verified. |
