摘要
引入通度概念处理河道不规则边界，用ＡＤＩ算法求解沿水深平均方程，破开算子法解悬移质不平衡输沙方程及河床变形方程，建立了平面二维河道水流泥沙数学模型，并通过物理模型试验对数学模型进行检验。
A 2D horizontal mathematical model is established for sediment transport, in which a partial-cell parameter is introduced to treat irregular boundary, the ADI algorithm is used to solve the depth average turbulence equations, the method of spliting operators is used in calculating equations of sediment transport. The results calcuated are in close agreement with experimental data, which shows that this model can be used in engineering well.
