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.

2. You're designing a stilling basin and you need to know the minimum length of that basin and also how much energy loss will be achieved before flow is released into the downstream channel. Given the basin width is 10-feet, the flow rate is 240 CFS, the upstream froude number is found from hydraulic modeling to be 4.0. Solve the following: • Minimum length of the stilling basin. • Energy loss within the stilling basin (Calculate both energy loss in feet and in tons). • The depth of water being released outside of the stilling basin. • The Froude Number being released from the Stilling Basin. • Look at USBR Design of Small Dams and Write a paragraph (4-5 sentences) of the recommended stilling basin you would propose for the hydraulic scenario.

The coefficient of permeability below a dam is 12 m/day. The water in the upstream side is 32 meter higher than on the downstream side (level with the ground). To estimate the seepage below the dam, a flow net is graphically drawn such that the number of potential drops, Nd = 8 and the number of flow channels Nf = 3. The base of the dam is founded 1.8 m below the ground. Between the heel and the toe of the dam, a distance of 32 meters, there are 6 potential drops. a.
