Evaluation of groundwater potential zones using Remote Sensing data in upper Vaigai river basin, Tamil Nadu, India

Identification of groundwater prospective zones using irs-id liss iii and pump test methods

“…Residual mounts, residual mount complex and linear ridges: These geomorphic features are considered as poor in groundwater prospecting (Sankar, 2002). Residual mounts are formed by the prolonged erosion and weathering of pre-existing surface features of the plateaus, plains and of even original complex tectonic mountain.…”

“…Groundwater prospecting in pediments can be considered as normal to poor (Sankar, 2002), but presence of any lineaments or fiactures can provide some scope for movement of groundwater and hence the prospecting for groundwater exploration. According to Philip and Singhal (1991) (Fig.…”

“…Similar attempts have been made in the generation of different thematic maps for the delineation of groundwater potential zones in different parts of the country (Obi Reddy et al, 1994;Krishna Moorthy and Srinivas, 1995;Rao et al, 1996;Reddy et al, 1996). Satellite remote sensing has been proved beneficial in hydrogeomorphological mapping (Vaidyanathan, 1964;Prithviraj, 1980;Das et al, 1997; Kumar and Tomar, 1998;Tomas et al, 1999;Pratap et al, 2000;Subba Rao et al, 2001, Sankar, 2002Jagannadha Rao et al, 2003).…”

Integration of thematic maps through GIS for identification of groundwater potential zones

“…Temporal data from remote sensing enables identification of groundwater aquifers and assessment of their changes, whereas, geographical information system (GIS) enables user-specific management and integration of multi-thematic data. GIS and remote sensing applications have been used by numerous scientists in mapping of groundwater potential zones (Venkatachalam et al, 1991;Ghose, 1993;Krishnamurthy et al, 1996;Pradeep, 1998;Saraf and Choudhary, 1998;Sankar, 2002;Khan and Moharana, 2002), rainfall runoff modeling (Das et al, 1992;Jain et al, 1996;Pal and Agrawal, 1999) and in many other applications. Pukhan et al (1999) delineated groundwater potential zones in the West Garo Hills of Meghalaya using remote sensing and GIS techniques.…”

Delineation of groundwater potential zones and zones of groundwater quality suitable for domestic purposes using remote sensing and GIS

“…Karanth & Seshu babu (1978), Moore (1978), Raju et al (1985), Palanivel et al (1996), Sree devi et al (2001) and Sankar (2002) applied remote sensing techniques in the delineation of groundwater potential zones. Many researchers Krishnamurthy & Srinivas, 1995;Kamaraju et al, 1996;Krishnamurthy et al, 1996;Khan Subhan & Asif Mohd, 1997;Ravindran, 1997;Saraf & Choudary, 1998;Ashok Kumar, 1999;Krishnamurthy et al, 2000;Murthy, 2000;Srivastava & Bhattacharya, 2000;Shahid et al, 2000;Khan & Moharana, 2002) have applied remote sensing techniques and GIS applications in delineation studies of groundwater resources and potential zones.…”
