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.

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.
