The depth of flow of water at a certain section of a rectangular channel 4 m wide is 0.5 m and the flow rate is 16 m3/sec. If a hydraulic jump takes place on the downstream side, fing depth of flow after the jump.

the flow rate is 1.2 m3/s per meter of channel width. (a) Compute the velocity and water depth at the top of the budge (hmax= 0.1 m). Characterize the flow there. (b) Rework the problem for a flow rate three times as large.

4.58. A trapezoidal canal has a longitudinal slope of 1%, side slopes of 3:1 (H:V), a bottom width of 3.00 m, a Man- ning's n of 0.015, and carries a flow of 20 m³/s. The depth of flow at a gaging station is observed to be 1.00 m. Answer the following questions: (a) What is the normal depth of flow in the channel? (b) What is the critical depth of flow in the channel? (c) Classify the slope of the channel and the water sur- face profile at the gaging station.

Determine the velocity of flow after hydraulic jump through a 1 m wide channel if the velocity of flow before jump was 2 m/s and the depth was 0.2 m.
