A rectangular channel 6.1 m wide with n = 0.014 is laid on a slope of 0.001 and terminates in a free overfall. Upstream 300 m from the overfall is a sluice gate that produces a depth of 0.47 m immediately downstream. (a) For a discharge of 17.0 m3 /s, draw the NDL. CDL and the water surface profile that occurs in the channel. Do you expect a hydraulic jump to occur in the channel? (b) From the overfall up to a location where the depth is 1.2 m, compute and plot the water surface profile using the direct step method. please solve it in a simple way

Highway Drainage

Highway drainage is the process of extracting and regulating the excess surface water on the pavement by giving the desired slope. The construction of a highway drain helps to divert the water present on the surface, and sub-grade by the means of slope. Highway drainage systems are a necessary part of smooth functioning of traffic, since the highway drainage systems provide proper disposal of unwanted substances from the highways.
