Groundwater Potential Zoning in Tikamgarh District of Bundelkhand Using Remote Sensing and GIS

Abstract

This study was conducted in Tikamgarh district of Bundelkhand, Madhya Pradesh, India to spatially delineate the groundwater potential zones using the integrated RS-GIS and MIF techniques. To do so, eight major biophysical and environmental factors like drainage density, geomorphology, geology, lineament density, land use/land cover, rainfall, slope and soil were considered. All the factors and their features have been assigned weights according to their relative importance and their normalized weights were calculated using the multi influence factor technique. Groundwater potential zoning map has been prepared through weighted overlay model in GIS environment after integrating all the thematic layers. The entire district has been classified into five different groundwater potential zones-Very Good, Good, Moderate, Poor and Very Poor depending on the likelihood of availability of ground water. Greater portion of the study area (40.60%) fall within the poor potentiality zone. About 3.10% and 11.54% of the total area fall under the very good and good potential zone respectively. 38.60% of the total area comes under the moderately potentiality zone. Only 6.16% of the total area fall under the very low potential zone. It shows that the applied technique produces considerably reliable results for this study which may facilitate the decision makers to formulate an effective plan for the study area.
