Groundwater is one of the most significant natural resources of the country. The
unconstrained exploration and non-judicious use of groundwater is causing a fall
down in water table in different areas of the country. However, the situation is more
severe in arid and semi-arid areas of the country. Therefore, in order to replenish
depleting ground water resources, there is a need for site explicit artificial groundwater
recharge by isolating suitable sites in different regions of the country. In this study,
an effort was made in this course to estimate groundwater recharge for Sonar subbasin
in central India. The study was conceded out for a period of 38 years during
1972-2010. The HELP3 (Hydrologic Evaluation of Landfill Performance version 3.0)
model based on water balance method was used for study. The groundwater recharge
was ass ess ed for 12 i dent i f i ed sites l ocated i n S onar sub-basi n on t he basi s of
s oi l types and geology. The soil profile prepared for HELP3 model using well-logs
was used to estimate site-specific groundwater recharge as well as for whole Sonar
sub-basin. The study reveals that about 4.627% of cumulative average annual
precipitation is added to groundwater recharge, which is not adequate to replenish
groundwater. Therefore, it is essential that this depletion to groundwater, if not
rejuvenated artificially, will cause water table to fall down which will affect
hydrological processes and socio-economic life of people residing in Sonar sub-basin.
