本文主要基于Dey （2003）在水平的U形渠道上的试验，运用堰高为零的薄壁堰模型，采用曲线拟合、无量纲分析的方法得出U形渠道上流量关于跌坎边缘水深的解析式。这种量水方式不仅能够运用于清水的测量，而且能够作为测量含沙量较大的量水设施。得出公式简单，便于实用，计算精度相对误差在5.26%以内。

This article is mainly based on Dey(2003) test at the level of the U-shaped channel ,using the model of sharp crested weir with zero crest ,curve fitting, dimensionless flow analysis method derived the equation of discharge with the water-height on vertical drop.This way of water measurement not only used in water without impurity,but also used as a measurement facilities of water with a certain amount of sediment concentration. Derived formula in this article is simple ,easy and practical;the relative error is within the accuracy of 5.26%.
