Abstract

It is difficult for hydraulic calculation of horseshoe cross section in open can al flow because of its complex cross section.The formulas of hydraulic elements and iterative normal depths for standard I and Ⅱ type horseshoe cross section are deduced,and the demarcation discharge for distinguishing depth range in the cross section is presented in this paper.It can be applied to practi ce work.
