Question: please answer both parts of this question question a a...

a) A short grass V-drain channel with side slopes of 6 horizontal to 1 vertical, slopes at 0.001. What is the flow rate for a normal depth of 0.25m, 0.5m, 0.75m, 1.0m, 1.25m?

Correct Answers should be: (84L/s, 533L/s, 1.57m3/s, 3.38m3/s, 6.14m3/s)

b) The channel in question 4 has a design capacity under certain flooding conditions of 2.56m3/s. What will the flow depth be? If the flow depth must be less than 0.6m, what base width for a trapezoidal channel with the same side slopes be made?

Correct answers should be: (0.90m, 4.85m)
