The maximum discharge of a river during floods is 200 cu.m./s. A weir is constructed across the river where a road bridge is provided over the weir which divides it into a number of openings each having a span of 4.5 m. It is required to determine the number of openings needed in order that the head of water over the crest should not exceed 1.8 m. Assume velocity of approach to be 4 m/s. Use Francis Formula.

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.
