Abstract

Groundwater recharge is an essential component in groundwater systems and significant in efficient and sustainable management of groundwater resources. In addition, it is also the most difficult quantity to determine. However, because it is nearly impossible to measure directly, numerous methods, ranging widely in complexity and cost, have been used to estimate recharge. Study of the groundwater recharge is important and to determine  the recharge estimates based on the scale of space and time. In this paper, various techniques for predicting groundwater recharge are outlined and critically assessed concerning their limitations. Multiple methods for predicting groundwater recharge were discussed, involving the ?uctuated of water-table method (WTF), Darcian approach, the water budget, soil water balance approach, rainfall infiltration factor, tracer techniques which involving chloride mass-balance and isotope method, all of which approached with dissimilar of assumptions and data requirements.
