Groundwater level has been declined continuously due to overexploitation and mismanagement of water resources, which leads severe problem in arid and semi-arid regions of the world. Geostatistics and Geographical information system (GIS) are the efficient technology to manage the groundwater resources. In the present study Linear regression method and Mann Kendall's test are used with GIS technology to understand the spatio-temporal behavior of Ground Water Level (GWL) in Loni and Morahi watershed of Unnao and Rae Bareli district Uttar Pradesh, India and also estimates the groundwater resources as per Groundwater Estimation Committee (CGWB, 2012) guidelines and identifies that Sareni block of Rae Bareli district and Sikandarpur Karan block of Unnao district are fall in critical category. As for the results, in both pre-and post-monsoon seasons, 61% wells showed decreasing (falling) trends.
