Flow enters a long, rectangular channel at its upstream end from under a sluice gate. The channel has b = 3 ft, n = 0.013, and S0 = 0.02. The flow depth at the entrance (opening) is 0.6 ft and the discharge is 30 cfs. 1) Find the normal and critical depths and identify them on the Picture 2) Classify the slope and identify the transition profile (M1, M2, S1 etc). Sketch the water surface profile by hand (qualitatively) on the Picture.
