针对游荡型河道的演变特征，将主流摆动和河岸崩塌的计算模式与平面二维水动力学模型相结合，建立了游荡型河段滩岸崩塌的计算模型。介绍了滩岸横向冲刷距离计算和河岸稳定性分析的方法。描述了游荡型河道水沙数学模型计算中的边界处理方法、河岸横向冲刷与崩塌过程计算和河岸形态修正的主要步骤。该模型有效解决了崩岸尺度与河宽尺度不匹配的问题，能够模拟河岸后退或淤长过程。

According to the evolution characteristics of wandering rivers, by the combination of mainstream swing and bank collapse calculation mode and 2D hydrodynamic model, the calculation model of bank collapse in wandering river reaches was es-tablished. The methods of bank transversal scouring calculation and stability analysis were introduced. The main steps including the boundary condition treatment, calculation of transversal scouring and collapse process of the bank and bank morphology modi-fication were described. By the model, the mismatching in the scales of bank collapse and river width can be tackled effectively and the deposition and erosion process of bank can be simulated.
