Groundwater potential modelling in a soft rock area using a GIS

Delineation of Groundwater Potential Zones using Remote Sensing and GIS Techniques in Kanakanala Reservoir Subwatershed, Karnataka

“…A weight (1-9) represents the virtual importance of a parameter and the objective (Boobalan and Gurugnanam, 2016) which was given by Multi Influencing Factor (MIF). There is no standard scale for simple weighted overlay methods, for this purpose, criteria for the analysis are defined and each parameter was given its due importance (Saraf and Choudhury, 1998;Chaturvedi et al, 1983;Raj and Sinha, 1989;Baldev et al, 1991;Gustafsson, 1993;Krishnamurthy and Srinivas, 1995;Saraf et al,1997;1998;Shahid et al, 2000;Jasrotia et al, 2007a;Jasrotia et al, 2012b;Mandal, 2011;Sedhuraman et al, 2014 etc). The weights and rank have been given by considering the works carried out by Krishnamurthy et al, (1996), Dey (2014) and Waikar and Nilawar (2014).…”

Groundwater Assessment through an Integrated Approach Using GIS and Electrical Resistivity Technique: A Case Study from the Bullom Group of Sediments in Sierra Leone

“…The same lithology forming different geomorphic units will have variable porosity and permeability, thereby causing changes in the potential of groundwater. Surface hydrological features like topography, drainage density, water bodies, etc., play an important role in groundwater replenishment [2]. For any developmental activity, both surface and groundwater sources are the main components depending on their quality and availability.…”

Application of remote sensing, GIS and MCA techniques for delineating groundwater prospect zones in Kashipur block, Purulia district, West Bengal

“…Several conventional methods such as geological, hydrogeological, geophysical and photogeological techniques are being used to delineate groundwater potential zones (McNeill 1991;Lillesand and Kiefer 1994;Teeuw 1995;Meijerink 1996;Sander et al 1996;Edet et al 1997;Taylor and Howard 2000;Shahid et al 2000;Srivastava and Bhattacharya 2006;Sharma and Kaur 2012;Fashae et al 2013;Selvam et al 2014;Jhariya et al 2016). In recent times, digital techniques come out as a rapid and cost-effective tool, and are being used to integrate different data to decipher groundwater potential zones.…”

“…In recent times, digital techniques come out as a rapid and cost-effective tool, and are being used to integrate different data to decipher groundwater potential zones. In recent times, many workers have used the approach of RS and GIS for delineation of groundwater potential zones and artificial recharge sites (Chatterjee and Bhattacharya 1995;Teeuw 1995;Krishnamurthy et al 1996;Saraf and Choudhary 1998;Shahid and Nath 1999;Goyal et al 1999;Murthy 2000;Obi et al 2000;Pratap et al 2000;Shahid et al 2000;Jaiswal et al 2003;Srinivasa and Jugran 2003;Kamal and Midorikawa 2004;Nag 2005;Sener et al 2005;Sreedevi et al 2005;Gustavsson et al 2006;Srivastava and Bhattacharya 2006;Singh et al 2007Jasrotia et al2007Kumar et al 2007;Chenini et al 2010;Machiwal et al 2011;Talabi and Tijani 2011;Kuria et al 2012;Gumma and Pavelic 2013;Nag and Ghosh 2013;Nag and Saha 2014;Olutoyin 2014;Nag and Ray 2015). Furthermore, GIS is also being used for multi-criteria analysis for groundwater resource evaluation (Saraf et al 2004;Rao and Jugran 2003).…”
