A highway median channel is to be sized to accommo- date a peak runoff rate of 2.4 m³/s. Regulations require that the channel side slopes be 3:1 (H:V), and site con- ditions require a lining with an n value of 0.020 and a longitudinal slope of 0.8%. Determine the dimensions of the most efficient trapezoidal section.

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.
