AbstractGroundwater reservoir (GR) of both local precipitation and surplus water transferred from the Han River Basin is an effective method to prevent further lowering of the groundwater table. In this study, when the different volumes of infiltration water from the fuzzy mathematical analysis were input in the simulation, the rate at which the groundwater table rose ranged from 1.47 to 3.45 m/a. The effective storage rate (ESR) values of GR and the local reservoir was calculated, and ranged from 80.50 to 90.95% and from 49.66 to 80.90%, respectively. In GR, the ESR decreased as artificial recharge increased. Comparison of the ESR values between local reservoir and GR showed that if the volume of artificial recharge water available was < 7.86 × 108 m3/a, then GR was a better storage method than the local reservoir. According to our results, this situation would occur 80.30% of the time.
