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.

Problem 7-40
A circular pipe has a diameter of 1m, bed slope of 1 in 1000, and Manning's roughness coefficient equal to 0.01. It may be treated as an open channel flow when it is flowing just full i.e., the water level just touches the crest. The discharge in this condition is denoted by Qull- Similarly, the discharge when the pipe is flowing half-full, i.e. with a flow depth of 0.5 m is denoted by Qhalf. The rato Qull/Qhalf is

You must determine the normal depth for a flow in a rectangular canal. Presume flow to be uniform, the base of the canal to be 8m wide and the slope to be critical. The flow is 10 m3/s and the Manning coefficient is 0.012.
Three reservoirs are connected by pipes as shown below. Water surface elevations for Reservoirs C and D are 65 ft and 60 ft, respectively. A gate valve is installed in the pipe between junction B and Reservoir D. If the flow rate from Reservoir C to junction B is 7 cfs and the gate valve is fully open, compute the following: (a) the flow rate for the pipe between junction B and Reservoir D, (b) the flow rate for the pipe between Reservoir A and junction B, and (c) the water surface elevation for Reservoir A. The minor head loss coefficient is 0.19 for the fully open gate valve. The minor head loss coefficients are 0.5 for pipe entrances at the reservoirs and 1.0 for pipe exits at the reservoirs.
