Geospatial Assessment of Groundwater Potential Zone in Chennai Region, Tamil Nadu, India

The major source of drinking water is Groundwater for human life. The current study utilized the geospatial techniques, to identify the groundwater potential zones in Chennai region. The calculable parameters used to conduct this study such as soil, land use/land cover, geomorphology, geology, slope, rainfall, lineament, drainage density, lineament density and NDVI which has been derived to identify the groundwater potentiality in the research area. The weighted overlay technique determines the influence of various parameters based on the assigned weights. The study highlighted the groundwater potential zones in five categories such as very low, low, moderate, high and very high. The result reveals that western and south western zones of the Chennai region records 60% dominant in groundwater. The study will also enhance the stakeholders for the purpose of planning, resource management and other developments in the study area.
