Abstract: Appling the critical submerged theory presented to the research of flow over broad-crested weirs, the discharge formula which the results of computation coincide with the present computing method is obtained in this paper .

Key words: broad-crested weir flow, critical submerged, coefficient of discharge, coefficient of velocity

摘要： 将笔者提出的临界淹没理论引入宽顶堰流研究, 得到了与现行方法计算成果一致的流量计算公式.公式结构简单, 计算工作量较小, 可供实际工程参用.
