A Study on the Impact of Landuse Pattern in the Groundwater Quality in and Around Madurai Region, South India-Using GIS Techniques
MetadataShow full item record
The study was aimed to identify and delineate the groundwater potable zone in and around Madurai region. The study area is composed of Charnockites and Khondalites of Archaean age. The information of Lithology, geomorphology and land use/land cover was generated using the Resourcesat (IRS P6 LISS IV) and Survey of India (SoI) toposheets of scale 1: 50,000 and integrated them with GIS to identify the groundwater potable zones of the study area. On the basis of hydrogeomorphology, groundwater potential zones was identified and delineated. From the overlay analyses of landuse and EC, it is inferred that poor category groundwater is found in the scrub forest, current fallow, canal and scrub with land areas.
