There is a scour in front a vertical wall due to wave erosion. Assuming perfect reflection and shallow water conditions, determine the water depth under the node nearest the wall, if wave height and period are known at the wall. Assume an equilibrium scour depth such that maximum horizontal water particle velocity at the bottom is ≤ 3 m/s.

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.
