On Iteration Algorithms of Uniform Flow Depth and Critical Water Depth in Open Channels

GE Jie-zhong~1,WANG Cheng-xian~2(1.Hengyang Water Conservancy and Hydroelectric Power Planning and Design Institute,Hengyang 421008,China;2.North China Institute of Water Conservancy and Hydroelectric Power,Zhengzhou 450011,China)  
The traditional trial method and referring-to-diagram method are very tedious for the computation of uniform flow depth h-0 and critical water depth h-k in open channels.Through long-term practice,iteration method is summarized and iteration algorithms of open flow h-0 and h-k of trapezoid section,U section and round section are offered,which are tested with mathematical method.Compared to traditional method,iteration method is simpler and more precise.
