| Abstract: | A 2-D flow-sediment mathematical model is established.The flow field is calculated by using zero-equation turbulence model with boundary-fitted coordinate system.The concentration field of suspended sedimentis calculated by using diffusion equation.The sediment deposition and the horizontal axis circulation flow are simulated and their relationship is also analyzed. |

| Keywords: | lateral trenches stream function and vorticity suspended sediment diffusion horizontal axis circulation flow |
