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. …
Question
A trapezoidal channel is 6.0m wide and has side slope of 0.5 H: 1 V. If the bed slope of the channel is 0.0004 and the Manning's n=0.02, find the discharge which can make the channel a hydraulically efficient section.
