(a) A 200 m wide natural stream, whose cross-section can beapproximated by a rectangular cross-section, contains a dischargeof 80 cumecs. If the specific energy of the flow is 1.5 timesthe minimum specific energy, determine the two possible depths offlow.

(b) The base width of a trapezoidal channel is 8 meters, and the slopes of the walls are 1V:3H. The bedslope of this earthen channel is 7*10^-4 and its roughness, n,is 0.022. If the discharge is 0.022 cumecs, what is thenormal depth of flow?
