Abstract
The observation based on field as well as secondary data collected from the various observation wells in the district of Varanasi during pre- and post-monsoon periods which show continuous decline in the groundwater level during the year 2009�15 except year 2012. After the analysis of hydrogeological and rainfall data, the groundwater behaviour of the area has been accessed. The correlation among rainfall, sub-surface lithology and groundwater level have been carried out to access the interrelationship of these factors. Thickness of clay and fine sand are governing factors for groundwater level under phreatic condition in the study area. The groundwater regime has strong relationship with rainfall and sub-surface soil condition. The groundwater is under stress condition particularly in the northern part of the study area due to lower rainfall in comparison to excessive groundwater withdrawal and significant thickness of clay layer below the ground surface. � 2021, The National Academy of Sciences, India.
