Abstract:

Artificial recharge is a technique used to replenish the groundwater resources which exploited by pumping for irrigation and drinking purpose. An artificial recharge structures are practiced in the hard rock regions of Tamil Nadu for groundwater restoration and management.The effectiveness of recharge structures in improving the recharge process has been evaluated for different recharge structures, namely, check dams, recharge shaft in percolation pond and recharge borewell. The recharge during the northeast monsoon for a period upto December is about 11.4 per cent and during the southwest monsoon for a period upto September is about 15.6 per cent. Natural recharge, depth of increase in groundwater is 1.5 m whereas the areas having artificial recharge structures the increase in groundwater table is 4.7 m. The recharge rate of a check dam and recharge shaft in percolation pond were estimated as 0.27 m3/m2of pond¬ing area/month and 0.54 m3/m2of ponding area/month respectively. The recharge shaft in percolation pond was found to be more effective in recharging the groundwater.
