Groundwater is a treasured underground resource, which plays a central role in sustainable water management. However, it being hidden and dynamic in nature, its sustainable development and management calls for precise quantification of this precious resource at an appropriate scale. Chance of getting good groundwater at shallow depths for irrigation is always considered as a blessing for the farmers. Hence, a correct estimation good groundwater potential is expected to increase the crop cover in most of the rainfed areas. In the present study, integration of remote sensing (RS), geographic information systems (GIS) and analytical hierarchy process (AHP) techniques is used for assessment and delineation of groundwater potential in Kantamal catchment of middle Mahanadi river basin. Relevant thematic layers having significant influence on groundwater occurrence viz land slope, drainage density, land use and land cover, dynamic ground water were used in this study. These thematic layers and their features were assigned suitable weights based on the conceptual frameworks of AHP. The study area has been demarcated into three groundwater zones, namely ‘good’, ‘moderate, and ‘poor’. Good, moderate and poor category occupies 9532 km2 (51%), 10297 km2 (47%), and 269 km2 (2%) of the total catchment, respectively.
