Abstract: The numerical model proposed in the previous paper is tested in this paper.Through simulating bank retreat processes for a schematic river reach under different bed score and deposition conditions,it indicates that the rate of bank retreat during scouring is greater than that in deposition.Then,the full bed deformation process of the Huayuankou Laitongzhai wandering reach in the lower Yellow River is simulated numerically,and good agreements are obtained between calculated and prototype-measured data such as the water level,velocity fields,and cross-sectional profiles variations.Both examples show that the proposed model is capable of simulating the longitudinal deformation of riverbed,and the process of bank retreat and advance,especially the bank lateral erosion and failure process.
