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.

A trapezoidal channel is 5.0 km long with the side slopes of Z=0.5constructed in clay soil. Up to the first 2 km, the bed-width of thechannel is 4.90 m and the depth of flow is 1.05 m. Thereafter, the bedwidth and the depth are 4.0 m and 0.885 m, respectively, right up tothe downstream end of the channel. Estimate the total seepage lossthrough the channel by Moles-Worth Eq.
A trapezoidal channel with sidewalls of 60 degrees has a bottom width of 4 m at total depth of 5 m and has a constant bedslope of 0.005.
