Design a concrete-lined canal to carry a discharge of 10,000 cfs. The canal has a Manning’s n = 0.015 and is to be laid on a longitudinal slope of 0.0007. If the canal is designed to have a trapezoidal cross section with a side slope of Z = 1.5 and a bottom width/normal depth ratio of b/yn = 3.0, determine its required bottom width, depth, and free board. What is the Froude number (Fr)? Will the canal have a supercritical flow?
