Abstract
This study was conducted to estimate groundwater reserves within a designated depth. Three methods were applied to one representative county in southern Gyeongsang province, South Korea, to estimate the groundwater reserves in the aquifers. Estimated amounts of groundwater reserves in the region ranged from $20.2{\times}10^9m^3$ to $68.7{\times}10^9m^3$ (average $37.9{\times}10^9m^3$). Groundwater recharge obtained with a recharge ratio of 16.6% was $1.1{\times}10^9m^3/year$. Exploitable groundwater with an assumption of decadal-cycle minimal rainfall of 977.0 mm/year was approximated as 72% ($0.8{\times}10^9m^3/year$) of the total replenished water by recharge. The volume of recharge and exploitable water accounted for only 1.1% and 0.8% of groundwater reserves, respectively, which indicates substantial capacity of the reservoir to supply groundwater in an event of unexpected droughts. Nonetheless, each groundwater well should strictly comply with its allocated pumping rate to avoid alluvial groundwater depletion.
