A trapezoidal channel having a bed width of 6 m and a side slope of 1: 1 is discharging water at a rate of 8.0
/s. Calculate the specific energy of water if the depth of flow is 2.0 m. What is the alternate depth to the observed depth?

For a trapezoidal channel with a bed width, b = 6.0 ft and a side slope, t = 2, find the critical depth if

a. Q= 150/s

b. Q = 75
