A Conceptual Design Model to Groundwater Recharge in Dense Urban Area Roads

Abstract

As increasing of Urbanization, the soil surface which is permeable through which groundwater recharge by infiltration can occur is reducing, this is resulting in much less groundwater recharge and greatly increased surface runoff. This Paper deals with the increasing of groundwater table utilizing of road runoff or stormwater through artificial recharge techniques. Infiltration devices that redirect surface runoff to the subsurface environment should be adopted, the infiltration system like infiltration trenches can be used to increase the groundwater table and the use of infiltration trenches has proven to be useful to reduce runoff in urban surface. By making continuous infiltration trenches in an area below the footpath and providing a filter media in it which consists of different layers of gravel and sand. Due to which filtered water goes inside the earth's surface and infiltration increases and the maximum portion of surface runoff go inside subsurface and stormwater management can be managed by using this technique. The methodology, applications, design & calculations are presented and discussed.
