Abstract:
Quantification of the rate of natural ground water recharge is a pre-requisite for efficient
ground water resource management. It is particularly important in regions with large demands
for ground water supplies, where such resources are the key to economic development. However,
the rate of aquifer recharge is one of the most difficult factors to measure in the evaluation
of ground water resources. Estimation of recharge, by whatever method, are normally
subject to large uncertainties and errors. In this paper, various methods of estimating natural
ground water recharge are outlined and critically reviewed with regard to their limitations and
associated uncertainties.
