| Abstract: | Based on the unsteady flow and laws of sediment movement. The finite element method is employed to deduce the discrete equations,and a finite element model is established. The mass concentration and the pre estimated and verified iteration are used to solve the equations. Simulation calculation is carried out with the flood occurring on Jinan reach of the Yellow River during the flood season in 1976 and shows that the calculated results, such as the water level, discharge, maximum and average velocity, cross sectional erosion and deposition, are in good agreement with the field and physical model data. |
