Question

2. Consider a trapezoidal channel with a width of 8 m and side slopes of 3:1 (H:V) and a channel slope of 0.015. If the flow rate through the channel is 50 m3/s and the Manning’s roughnesscoefficient is 0.017 (15 points)

(a) What is the critical depth?
(b) What is the normal depth?
(c) Classify the water slope
(d) What range of depths would be classified as zone 2?
