Lineament Mapping Using Remote Sensing and GIS Techniques in Part of WRC-1 Watershed, Chargarh River Basin, Central India

Abstract

The study comprises use of remote sensing and Geographic Information System (GIS) techniques for the identification of groundwater resource potential in response to the lineaments. The remote sensing IRS-Resource Sat-2, LISS-III false colour composite (FCC) Satellite images were utilized to conduct lineament data analysis of the Chargarh River Basin, especially with respect to the lithological setup and density and frequency of the lineaments. The area is covered by the Deccan basalt lava flows in the northern part and Quaternary alluvium in the southern part of the watershed. In all 116 lineaments are exposed in the central and northern part of the watershed. To study the significance of lineament trend and lineament intersection, lengths of the lineaments and intersections are considered with statistical analysis. It is observed that Tapi lineament has long and short fractures which has unique significance in the present study. The lineament/fracture analysis indicates a special structural pattern with orientation due North-South and East-West. In the watershed cross lineaments are dominant and the zones with high lineament intersections are feasible places for groundwater occurrences.
