A grass-lined roadside channel.( need only handwritten solution .otherwise downvote.)
A flow of 10.0 m⅔ is to be passed in a rectangular channel with the depth of flow equal to one-third of the width. The channel is lined with smooth concrete (n=0.014). Calculate the channel dimensions (B=? y=?) and its longitudinal slope necessary to carry the above discharge with a mean velocity of 2.5 m/s.
Water flows in a trapezoidal channel in which the bottom width is 3 m and the side slopes are 2:1 (H:V). The channel lining has an estimated Manning n of 0.02, and the longitudinal slope of the channel is 0.1%. If the flow rate is 150 m³/s and the depth of flow at a gaging station is 4 m, classify the water-surface profile, state whether the depth increases or decreases in the downstream direction, and calculate the slope of the water surface at the gaging station.

, in two columns, and box your final answer. 1. A concrete channel, rectangular in shape, is laid on a channel bed of slope 0.0010. At an upstreampoint, the depth of water is 1.5 m and 300 meters away, at a downstream point, the depth of flow becomes 1.17 m. If the channel is 4.5 m wide, and has the roughness coefficient of 0.013, find the approximate flow rate.
