Abstract

Ground water is an important natural source of drinking water for many people around the world. Further it is considered to be an essential element to maintain a proper balance between ground water fluctuation and rainfall distribution. Due to irrigation, urbanization and industrialization, the ground water level has declined to a larger extend. Hence in the present work an attempt has been made to analyse the groundwater fluctuation by taking the upper Ponniyar watershed as a study area using geographical information system (GIS). Also a correlative study has been made between the rainfall distribution and ground water fluctuation during the period from 1992 to 2012.
