摘　　要：对于明渠均匀流水深h0和临界水深hk的计算,传统的试算法和查图法比较繁琐.经过长期的工作实践,总结出了迭代算法,列举了梯形(含矩形)、U形和圆形断面明流h0和hk的迭代算法.并用数学的方法进行了验证.与传统的计算方法相比,迭代算法更为简便、精确.The traditional trial method and referring-to-diagram method are very tedious for the computation of uniform flow depth h0 and critical water depth hk in open channels. Through long-term practice, iteration method is summarized and iteration algorithms of open flow h0 and hk 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.
