Design for integrated storm water Drainage system of rural road

Drainage is the process of interception and removal of water from over and under the vicinity of the road surface. Drainage can be surface or subsurface. In the study area there is Dry River is passing near to the road, so in monsoon season the other river stream which passing through the road which make the damage to pavement. There is insufficient drainage facilities which could not passing through it. By collecting the last 10 years rainfall data thus we can measure the intensity of water flowing. There is the Chainage data which have every specific distance with water flow level. At high flow level there is need to provide efficient drainage system. Using this information, calculate the water flow discharge and make the design of culvert at the specific area. Another option is to remove surface water by permeable pavement surface at shoulder. Which drain out the surface water to subgrade. Pavement surface incorporate good drainage can be expected to have a design life of two to three times of un-drained pavement sections.
