Take note: Answer and write your solution on a clean paper clearly. During a flood flow the depth of water in a 12 m wide rectangular channel was found to be 3.5 m and 3.3 m at two sections 300 m apart. The drop in the water-surface elevation was found to be 0.18 m. Assuming Manning’s coefficient to be 0.023, determine the following: a. Average value of k? b. Estimate the flood discharge through the channel ?
