A study on Geo spatial based approach for Delineation of Ground water potential zones

A case study was conducted to find out the groundwater potential zones in Virudhunagar district, Tamil Nadu, India with an aerial extent of 4243.23 sq.kms. The thematic maps such as geology, geomorphology, soil hydrological group, land use / land cover and drainage map were prepared for the study area. Worldwide rapid growth of population, industries and agricultural activities brought about a steep increase in water demands which have to be met from available surface and ground water resources. Ground water has gained prime importance during the past decades. This has been mainly on account of its dependability throughout the year and in particular during the periods of scanty rainfall and drought condition. The Geospatial technology has proved very efficient in assessing the ground water potential of any area. This paper aims Delineating the groundwater potential zones of a location by utilizing the existing data obtained through geological and soil surveys. The capabilities of GIS and Remote sensing has been harnessed to map the areas with potential ground water sources which could be used to easily identify and recharge the areas for future uses. This GIS based output result was validated by conducting field survey by randomly selecting wells in different villages using GPS instruments. The coordinates of each well location were obtained by GPS and plotted in the GIS platform and it was clearly shown that the well coordinates were exactly seated with the classified zones.
