The cross-section of a river 30 m wide is rectangular. At a point where the bed is approximately horizontal the width is restricted to 25 m by the piers of a bridge. If a flood of 450 m³/s is to pass the bridge with the minimum upstream depth, describe the flow past the piers and calculate the upstream depth.

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.
