  1. In this paper, some characteristics of flow movement and sediment transport are analyzed by using the flume experiment data. the cross section of compound channel can be divided into four regions : the undisturbed region in main channel, the interactive region between channel and plain, the undisturbed region in flood plain and the boundary region. in the undisturbed regions, the distribution of longitudinal velocity along the depth has the feature of lograithmic. whereas, in the interactive region, the longitudinal velocity does not obey the logarithmic distribution law, but it can expressed as a revised logarithmic function by using a wake function. on the basis of the kinematic equation the velocity distribution of transverse velocity is obtained. in the boundary region, the longitudinal velocity obeys the law of parabolic distribution. furthermore, according to the simplified diffusion equation, the transverse distribution of sediment concentration in the interactive region is deduced. the analysis is in good agreement with the measured data

    本文根據的運動特點,將的復式斷面分為主槽平衡區、槽交互區、地平衡區及邊壁區等4個區,並給出了各區寬度的經驗公式.根據槽交互區垂線速分佈的變化特點,提出了附加尾函數的對數速分佈公式.在簡化水運動方程和泥沙擴散方程的基礎上,對槽交互區內垂線平均速及含沙沿橫向分佈進行了理論分析,提出了反映槽水交換強度的橫向渦粘性系數及橫向擴散系數的表達式,得到了垂線平均速及含沙沿橫向分佈的解析解,並與實測資料吻合較好
