IDENTIFICATION OF GROUNDWATER POTENTIAL ZONE USING REMOTE SENSING AND GIS TECHNIQUES FOR MANDYA TALUK
Chaitanya B. S.* and Shivakumar B. P.
A remote sensing and geographic information system (GIS) approach was used to define favourable regions for the construction of artificial recharge structures in Mandya in order to increase the well's longevity and stop the decreasing groundwater level patterns. Eight layers, including geology, geomorphology, slope, and topography, were analysed using GIS overlay analysis. Groundwater is a vital source of drinking water and agricultural water for the rural population, so adequate groundwater development is critical. The AHP-analytical hierarchical method was used in conjunction with a geographic information system (GIS) to map and evaluate groundwater yield potential in the Mandya taluk in this study. AHP has been extensively studied and it represents an accurate approach to quantifying the weights of decision criteria. The groundwater potential zone map thus obtained was categorized into five classes-very high, high, moderate, low and very low.[Full Text Article]
