A trapezoidal channel has a base of 25 ft and side-slopes of 1v:3h. It has a manning n = 0.022 and α = 1.22. The slope of the channel is 0.323%.   What are the nominal and critical depths if the flow is 500 cfs? What type of profile will the channel have if the depth of flow entering the channel is 1.2ft?
