DAM construction and variations in groundwater level - A case study of tonk district of Rajasthan

Increasing importance of water along with increasing scarcity has compelled human beings to find out the ways for providing them with maximum utilisation of available water as well as efficient utilisation. In this way dam construction for various purposes have played significant role. Recent findings about the groundwater level increase in surrounding areas of dams have taken attention. An effort has been done to find out the same in Tonk district of Rajasthan. Data of twelve years has been analysed which is in form of data taken for two time periods: pre-monsoon and post monsoon from the identified observation wells. Various statistical and cartographic techniques have been used to depict that it is not the flowing water or rivers, which is impacting the groundwater level in Tonk district but it is the proximity to the stored of water which is still in form of dams etc. And the sites which are near to Bisalpur dam in Deoli and Tordi Sagar in Malpura show better picture of groundwater level when compared to other far away sites or observation wells which are near to river. As it is well known that still water provides adequate time to surface water to percolate.
