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 7350 m long, 1050 mm concrete pipeline connects an upstream reservoir (watersurface elevation 433.3 m) to a downstream reservoir (water surface elevation 423.1 m). Adischarge valve at the downstream end is used to control flow; when this valve is fully open,the measured discharge in the pipeline is 920 L/s under the naturally available head difference.(a) Assuming fully developed turbulent flow and that all other local losses are negligible,estimate the loss coefficient k for the fully open valve (assume f = 0.015).(b) Because of increasing urban development, the flow under the natural head difference isconsidered to be inadequate and it is proposed to increase this flow with pumping. The head-capacity curve for the pump can be approximated by the equation H = 8 – 3.5Q2 in which H isthe total dynamic head on the pump (in m) and Q is the discharge (in m3/s). What is thedischarge that can now be obtained from the system where the pump is installed at a cross-section of the pipeline?
Water flows in a horizontal, rectangular channel initially 10 feet wide and 2 feet deep. The initial velocity is 6 ft/s. This flow encounters downstream a simultaneous downward step and constriction.

What specific energy, E, is associated with the flow as initially specified (at the upstream location)? c. What is the minimum energy needed to pass the full discharge at the downstream location? d. What is the height (Az) of the smallest downward step necessary for the upstream flow conditions to remain as specified?
