Abstract: Normal depth is a key parameter occurring in the design of canals. It also occurs in the analysis of varied flow in canals and natural streams. The open channel resistance equation involves implicit form for all the practical canal sections. The solution of the implicit equation for normal depth involves tedious method of trial and error. Presented herein are the exact equations for normal depth for various open channel sections.
