| Abstract | In order to meet the growing demand for groundwater in hard rock areas of India, man-made percolation tanks have become important structures for augmenting groundwater recharge. Keeping in view their increasing number and the cost involved in their construction and their temporal variation in percolation due to silting or desilting operations (if undertaken), it is vital to develop a proper methodology to evaluate the performance of these structures. A method employing the mass balance of environmental chloride in the tank has been developed for this purpose. The results obtained using this method at one experimental site indicate that an average of 30-35% of impounded water is recharged through such a structure situated in granitic gneissic terrain of a semi-arid region of India. The remainder is lost through evaporation. The method developed is simple, inexpensive, and sensitive enough to observe the temporal variation in the recharge rate through such tanks (adapted from authors' abstract) |
