A concrete-lined trapezoidal canal is 20 ft. wide at the bottom with sides sloped 3 horizontal to 4 vertical. If the slope of the bottom is 0.0025 and the depth of water in the canal is 8 ft. what is the discharge? Assume n = 0.012 and use Kutter's formula for determining C. Choices: A.) 5750 cfs B.) 4750 cfs C.) 3750 cfs D.) 2750 cfs
