Water flows at 25 m^3/s down a rectangular channel made of unfinished concrete. The channel has a width of 4 m and a downward slope of 0.008, and the water depth is 2.6 m at the control section A. Calculate critical depth, normal depth and identify the channel surface profile. Determine the distance X from A to where the depth is 2.7 m (Control Section B). Use increments of Ay= 0.1 m (one increment only between 2.6 m and 2.7 m) Take n = 0.018.

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.
