Based on characteristics of broad-shallow shifting reach in Xinjiang region,the movable bed design was studied in this paper.By analyzing the influence of distorted scale and lightweight sand,the self-similar model, nature sand,and small scale was recommended in the typical river.Due to the limitation of field and difficulty of hydraulic boundary in the self-similar model design,the method of the partial was put forward.By analyzing the influence of different width of the bridge section and the error of the unit discharge in the typical river,the evolvement of bed form and back water in bridge section can be simulated in partial model.
