Abstract: In this paper, a number of approaches related to the study of the width of regime channels are analyzed and discussed. Then, the relation of the distribution of total shear stress on the bed and banks of a channel and the width of regime channels is presented and calculated with the measured data. According to the relation, the width of regime channels can be determined.

摘要： 首先对有关稳定河道宽度研究的方法和理论进行了分析和讨论。然后提出了总切应力与稳定河宽的关系理论并用实测资料进行了计算，据此可确定稳定河道宽度。
