The bottom of an open channel at a specified section is 2.0 m above a horizontal datum. The area of the cross section (rectangular section) of flow is 4.0
 , which accommodates a discharge of 8.0
 /s. The total energy is 3.0 m (measured from the horizontal datum). Calculate rhe depth of flow in the channel.

Calculate the geometric elements of a parabolic section with a cross-sectional area of 10.0
 and a top width of 4 m. If rhe section is replaced by a trapezoidal section with a 4.0-m bed width and 3:2 side slope, calculate rhe depth of flow, top width, hydraulic radius, and section factor.
