| Abstract: | 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. |
