	3.	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 本文根据漫滩水流的运动特点，将漫滩水流的复式断面分为主槽平衡区、滩槽交互区、滩地平衡区及边壁区等4个区，并给出了各区宽度的经验公式.根据滩槽交互区垂线流速分布的变化特点，提出了附加尾流函数的对数流速分布公式.在简化水流运动方程和泥沙扩散方程的基础上，对滩槽交互区内垂线平均流速及含沙量沿横向分布进行了理论分析，提出了反映滩槽水流动量交换强度的横向涡量粘性系数及横向扩散系数的表达式，得到了漫滩水流垂线平均流速及含沙量沿横向分布的解析解，并与实测资料吻合较好
