Calculation on normal depth of horseshoe cross section by iterative method

LU Hong xing,XIN Quan cai,HUA Li feng (College of Water Conservancy and Architectural Engineering, Northwest Sci Tech University of Agriculture and Forestry,Yangling 712100,China)  
It is difficult for hydraulic calculation of horseshoe cross section in open canal 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 practice work.
