摘　　要：本文对弯曲河道床面形态规律进行了较全面的理论分析与试验研究，给出了床面形态高度和波长的计算表达式，并用美国ＦａｌｌＲｉｖｅｒ原型观测资料进行了验证。In this paper, the bed form laws in channel bends are investigated. It is found that there are significant differences between the bed form characteristics of a river bend and those of a straight channel. The calculation formulas of the bed form height and wave length are given.The results of computation are in good agreement with that of measurements on the Fall River,in America.
