A rectangular channel with a base width of 3 m carries a discharge of 6 m3/s at a depth of 1.1 m. At downstream, there is a gradual rising of a channel bed of 0.1 m.

a) Plot the specific energy curve from y = 0.4 m to 1.3 m in a step 0.1 m and from the curve, determine the depth of flow at the downstream section. Label the graph and show your working answers clearly on the graph. *
