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.

QUESTION 30 In the figure shown, sub-critical uniform flow occurs in a 1.2 m width rectangular channel at the depth of 0.6 m. A hump of height 10 cm is placed in the bottom of the channel. Flow rate of the channel is 0.8 m/s. Assuming no energy losses, 1. Show that the flow depth on the step is 0.453 m(Y2) 2. If the flow depth on the step were to be critical depth (Y2) calculate the minimum height of the step (AH) Y-0.6 m Y: Q=0.8 m'/s DAH = 0.1 m
