Specific discharge of a wide rectangular channel is 10.0m2/s (Q 10.0m3/s/m). The channel consists of two long reaches having the following bed slope, So1 -0.0001 (for ABC), and So2 = 0.008 for (CDE), (see Figure 1) respectively. There are two gates to control the flow and the flow depth at the vena contractor after each gate is approximately 0.3m.
