Abstract: Kaliasot reservoir is under environmental stress due to siltation, human encroachment, and sewage input from various resources. Kaliasot Basin area in Bhopal and Raisen district has been identified as one of the problematic area under the semi critical category in terms of water crisis, encroachment and haphazard urbanisation. The study area is facing many problems like scanty rainfall, scarcity of water, increasing demand of water for irrigation, domestic & industrial purposes and deforestation. The research study employs an integrated approach by using GIS and Remote Sensing since groundwater conditions of the area are controlled by many parameters i.e. drainage, geology, geomorphology, lineaments, slope, land use and land cover. Various thematic layers have been generated and assigned weightages and ranks. These layers have been integrated in GIS software for generating Groundwater Potential Zone map of Kaliasot watershed. The area falls into five categories of groundwater potential zones i.e. excellent, good, moderate, poor and very Poor depending on the likelihood of availability of ground water. On the basis of this study it is found that only 13.44km² area is under Excellent and 110.97km² area is under good category of groundwater availability. An area of 59.75km² is found under moderate category whereas 7.97km² and 0.04km² area falls under poor and very poor category of availability of groundwater respectively.
