| Abstract: | Based on experimental results from a flume,a systematical study on the properties of sediment diffusion in turbulent mixing region at the mouth of cecum reach was made.The experimental data show that the sediment movements have similar structure at the turbulent mixing region.From the theory of similarity,a similarity function of sediment concentration was obtained.The sediment diffusion was simulated by numerical calculation,and the gradient of sediment concentration was analysed. Finally,a formula to estimate the sediment deposition rate caused by circulating flow was also established. |
