India has good average annual precipitation, but its poor distribution in space and time has led to the scarcity of groundwater in many areas. Artificial recharge to groundwater requires a composite procedure along with detailed morphometric and hydrogeological studies of the area. In Maharashtra State, a
programme was initiated to recharge the groundwater by making a cascade of earthen bunds, recharge ponds and using disused open wells. The effectiveness of artificial recharge programmes was evaluated by employing environmental isotopes (3H, 18O and D) in
Ozar watershed whereas recharge zones and effectiveness of different recharge sources were evaluated in BM-60 and Bamnod watersheds.
