Flow from a concrete channel (n = 0.017) falls freely into a reservoir at a rate of 7.8 m3/s. The width and longitudinal slope of the channel are 5 m and 0.0006, respectively. At the inlet of the reservoir, the flow becomes critical. Analyse the type of profile and plot the water surface profile using numerical integration and the direct step method with 4 steps.

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.
