Proceedings of the National Academy of Sciences, India Section A: Physical Sciences ( IF 0.9 ) Pub Date : 2021-03-09 , DOI: 10.1007/s40010-021-00735-y

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.

使用GIS在印度北方邦瓦拉纳西地区的部分地区进行地下水应力分析

季风前后,根据瓦拉纳西地区各观测井的实地观测数据和二次数据,这些观测数据表明,2009-15年期间(2012年除外)地下水位持续下降。根据水文地质和降雨数据,已经获得了该地区的地下水特性。为了获得这些因素之间的相互关系,已经进行了降雨,地下岩性和地下水位之间的关联。黏土和细砂的厚度是研究区潜水条件下地下水位的控制因素。地下水状况与降雨和地下土壤状况密切相关。
