Application of geo-electrical data to evaluate groundwater potential zone and assessment of overburden protective capacity in part of Sonebhadra district, Uttar Pradesh

Abstract

Groundwater potential zones and aquifer protection capacity were evaluated in the hard rock area in part of Sonebhadra District of Uttar Pradesh, India. Seventy-one vertical electrical sounding were conducted in the study area. The geoelectric properties obtained from the interpretation of the resistivity data were used to obtain some secondary parameters known as Dar-Zarrouk parameters. Thematic maps were prepared for overburden thickness, anisotropic coefficient, transverse resistance and longitudinal conductance of the study area. These maps were classified, weighted and integrated in ArcGIS environment by means of the Overlay weighted model. A suitable map which classified the groundwater potential zone of the study area into low, moderate and good was obtained. A further assessment of the longitudinal conductance was carried out to assess the protective capacity of the overburden material, the result obtained shows that the study area is dominated by moderate to good protective overburden material.

“…5). This curve type being a combination of H and K curve types are typical curve types that revealed the complexity of crystalline multi-faceted geologic terrain (Jayeoba and Oladunjoye, 2013;Ndatuwong and Yadav, 2014;Kayode et al, 2016). Qualitatively, these curves types often gives mirror image of the successive lithologic sequence from Table 9 The characteristics of the groundwater potentiality maps based on the applied MCDA models.…”

“…Furthermore, the average transverse resistivity ρ t varies from 13.4 to 5045 Ωm, which is more than the average longitudinal resistivity (Salem 1999). This indicates that the current flow and average hydraulic conduction along the lithology boundary are greater than those normal to the boundary plane (Ndatuwong and Yadav 2015).…”

Groundwater Potential Assessment Using Geoelectrical Data: A Case Study Of Phuket Island, Thailand

“…The geophysical method has played an important role in groundwater exploration for many years because of its reliability, ease of getting subsurface information, and nondestructive character. The electrical resistivity survey using Vertical Electrical Sounding (VES) method is the most popular geophysical technique for the assessment of groundwater potential (Ndatuwong and Yadav 2015). In the VES method, four electrodes including two current electrodes (A and B electrodes) and two potential electrodes (M and N electrodes) are used for the resistivity measurement of the subsurface.…”

“…Similarly, Gowd (2004) employed the VES method to correlate with the existing lithology and the weathered and fractured zones in both shale and limestone as the productive water-bearing zones having fresh groundwater potential. The estimation of some secondary parameters from resistivity data to assess the groundwater potential relies on a fundamental relationship between hydraulic properties and resistivity (Hasan et al 2018;Anbazhagan and Jothibasu 2016;Ndatuwong and Yadav 2015). In addition, the integration of secondary aquifer parameters calculated from resistivity data was mapped as a thematic map of groundwater potential zones using the Geo-Informatic System (GIS), which is an appropriate platform for the analysis of diverse datasets from groundwater mapping (Anbazhagan and Jothibasu 2016).…”
