Concept explainers

Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.

You are responsible for calculating the peak discharge for a culvert design in a smallwatershed in Washington, DC. The watershed area is 4 acres and currently has 30 % of its area ofindustrial (heavy areas) and 70 % of residential (single –family areas). The design manual suggestsyou design your culvert for a 10 return period. The watershed has a concentration time of2 hours. Calculate:a) What is the design peak flow?b) What is the impact of the runoff coefficient (C) range on your design?c) After you implemented your project, the residential area was entirely converted toindustrial areas. Would that affect you design? If yes, by how much?
