Deciphering groundwater potential zones in hard rock terrain using geospatial technology

Abstract

Remote sensing and geographical information system (GIS) has become one of the leading tools in the field of groundwater research, which helps in assessing, monitoring, and conserving groundwater resources. This paper mainly deals with the integrated approach of remote sensing and GIS to delineate groundwater potential zones in hard rock terrain. Digitized vector maps pertaining to chosen parameters, viz. geomorphology, geology, land use/land cover, lineament, relief, and drainage, were converted to raster data using 23 m×23 m grid cell size. Moreover, curvature of the study area was also considered while manipulating the spatial data. The raster maps of these parameters were assigned to their respective theme weight and class weights. The individual theme weight was multiplied by its respective class weight and then all the raster thematic layers were aggregated in a linear combination equation in Arc Map GIS Raster Calculator module. Moreover, the weighted layers were statistically modeled to get the areal extent of groundwater prospects with respect to each thematic layer. The final result depicts the favorable prospective zones in the study area and can be helpful in better planning and management of groundwater resources especially in hard rock terrains.

Delineating groundwater potential zones in a hard-rock terrain using geospatial tool

“…both directly and indirectly, that can be used in deciphering groundwater potential zones in hard-rock terrain (Dar et al 2011, Singh et al 2011a. These tools provide unique and powerful means for obtaining spatio-temporal information about earth resources within a short time (Gupta and Srivastava 2010).…”

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

“…For this purpose, criteria for the analysis are defined and each parameter is assigned importance Choudhury 1997, 1998). Researchers, such as Sarma and Saraf 2002;Khan and Moharana 2002;Nag 2005;Rokade et al 2007;Muthukrishnan and Manjunatha 2008;Prasad et al 2008;Chowdhury et al 2009;Dar et al 2010;Rashid et al 2011;Magesh et al 2012, Pandian and Kumanon 2013 also have applied this GIS modeling technique for delineation of groundwater potential zones in their research study area.…”

Groundwater recharge potential zones mapping in upper Manimuktha Sub basin Vellar river Tamil Nadu India using GIS and remote sensing techniques

“…In India, about 65 % of the country is underlain by hard rocks (Saraf and Choudhury 1998). A number of attempts on delineation for groundwater potential zones using remote sensing data have been made by Murthy (2000), Jaiswal et al (2003), Anbazhagan et al (2005), Sener et al (2005), Dinesh Kumar et al (2007), Kumar et al (2008), Chowdhury et al (2009), Yeh et al (2009Yeh et al ( , 2014Yeh et al ( , 2016, Adham et al 2010, Dar et al (2011, Venkateswaran and Ayyandurai (2015) and Prasanta Kumar Ghosh et al (2016). Geographic Information System (GIS) techniques facilitate integration and analysis of large volumes of data, whereas field studies help to further validate results Solomon and Quiel (2006), Kannan et al (2016) Satheeshkumar et al (2016) and Vijay .…”
