Popis: The Yamuna River is the part of vast Indo-Gangetic alluvial plain abides a huge scarcity of water in terms of both surface and groundwater resources. Artificial recharge is the most promising measure in the present scenario to improve the groundwater conditions of the area. In the present study artificial recharge sites were delineated using the important factors which plays a pivotal role in groundwater occurrence through Analytical Hierarchy Process (AHP) based modelling in Geographical Information System (GIS) environment. Datasets from different sources and Landsat-8 satellite images were used to assign the weightage for different parameters in accordance to their role in site selection for artificial recharging. The study shows that the sub-watershed-1 lies in the south-western upland of Agra district and sub-watershed-2 which is located in Firozabad district, occupies an area of 304 Km2 (42%) and 248 Km2 (35%) respectively, found under critical groundwater condition in terms of declining groundwater level. These sites are located mainly around the settlement areas of relatively higher elevation. Overall, 26% area (i.e., very low water level class in the study area) in the presented study exhibit poor groundwater conditions (i.e., 32–42 m bgl) and hence required an immediate treatment in terms of artificial technology in order to enrich the water stressed alluvial aquifers.
