Identification of Groundwater Potential Recharge Zones Using Remote Sensing and Geographical Information System: Tiruppur District, Tamil Nadu

Groundwater management studies integrate the concept of spatial planning by using GIS (Geographical Information system). There is a need to bridge the gap between existing demand and supply for concreting the sustainability pillars. This paper gives an attempt to identify groundwater recharge potential zones and propose artificial recharging sites spatially for the Tiruppur District, Tamil Nadu. Through Arc GIS, weighted overlay analysis has been done which requires seven thematic layers such as soil, lineament, drainage density, geomorphology, land use, geology and slope and classified into three classes such as good, moderate and poor. This technique of identifying potential zones is one of the effective ways of groundwater management. Groundwater recharge structure like check dams, boulder bunds and percolation tanks has been proposed spatially.
