Title: Research and application of flow and sediment mathematical model in tidal river
Abstract: Flow and sediment movement in tidal river has strong non-constancy,so the two-dimensional flow and sediment mathematical model for tidal river is established using finite volume method.The non-staggered grids and SIMPLEC method is adopted to discrete the flow equations.The model comprehensively considers the movement of non-uniform suspended sediment and bed load with good general applicability.Taking the Yizheng and Kou'anzhi reaches in the downstream of Yangtze River for examples,the calculation is performed in the condition of fixed bed and moving bed using the above model,and the results are in good agreement with the measured values,proving the reliability of the model.
