Groundwater prospective zones in basaltic terrain using remote sensing

Abstract

The study aims at investigating the relative role of landforms and lineaments as an integrated unit for the assessment of groundwater availability with an example of an area occurring in basaltic terrain. The article describes the use of remote sensing data for hydrogeomorphological mapping, zoning of the area into groundwater prospects and evaluation of zones by using well discharge data of handpumps located in the area. It has been found that the rocks, which are both, fractured and weathered, are more productive in groundwater discharge. The study shows that the lower elevation zones of micro-watersheds have better groundwater prospects.
