摘要:Assessment of groundwater vulnerability using DRASTIC model in GIS environment has become morewidespread for effective groundwater resource management. A study was carried out in Krishnagiri district, TamilNadu, India to develop an empirical DRASTIC model to identify the vulnerability owing to groundwater contaminationwith increasing population, industrialization and agricultural activities. The most important factors that control thegroundwater potential are depth of water, rainfall, aquifer media, soil media, topography, impact of vadose zone andhydraulic conductivity of the aquifer. Estimation of DRASTIC Index involves multiplying each parameter weight by itsrating corresponding to its study area and summing the total. Based on DRASTIC index values it was observed that thevulnerability in the study area falls between low vulnerability to high vulnerability. The results provide importantinformation for the local authorities and decision making personals for effective management of groundwaterresources.
