Groundwater potential zones identification and validation in Peninsular India

Groundwater mapping is essential for meeting the water requirement of people. Identification groundwater potential zone was attempted a watershed located in Kanchipuram district, Tamil Nadu, India. The Landsat 8 and 5 data were used land use/land cover analysis. For delineating zone, total seven thematic layers namely drainage density, slope, geology, soil, geomorphology, rainfall, observed levels considered during Afterwards converted into raster using GIS platform. Further, after assigning weights ratings to each layer, overlay analysis applied five zones delineated as very good, moderate, poor, poor. majority area has moderate zone. map also validated ROC method. 2005 shows highest accuracy compared rest year maps.
