초록

본 연구에서는 Kim et al. (2013)이 개발한 부정류상태에서의 지하수위 변동 해석모델을 이용하여 단위시간별 함양량을 산정하였다. 지하수위 변동 해석모델은 지하수의 흐름과 관련된 반응계수와 함양에 관련된 비산출율을 매개변수로 이용한다. 해석모델의 적용을 위해 제주도 한천지역의 관측정 중 강우에 대한 반응이 양호한 JW 공항과 JD 용담1지점에 대한 5년(2006-2010)간의 지하수위 관측자료를 이용하였다. 지하수위 해석모델은 국지적인 규모에서의 단위시간별(일별) 함양량 산정이 가능하며 지하수위 자료와 비교한 결과, 함양량과 매개변수가 지하수위를 잘 반영하고 있었다. 함양량 산정결과 JD 용담1 지점은 520.4~904.0mm (32.7~61.8%), JW 공항지점은 447.4~633.4mm (24.0~45.1%)로 나타났다. 개발된 해석모델은 지하수위 자료를 이용하여 매개변수를 추정과 단위시간별 함양량을 산정하는 방안으로 활용되기를 기대된다.

In this study, daily based groundwater recharge was estimated under unsteady state by using groundwater table fluctuation model developed by Kim et al. (2013). This technique analyzes groundwater variation characteristics by using reaction factor related with groundwater flow and specific yield related with recharge. For the application of this model, measured groundwater level at JD Yongdam 1 and JW Konghang for 5 years were used. This model can estimate daily based groundwater recharge and the computed groundwater levels showed good agreement with measured groundwater levels. At JD Yongdam 1 and JW Konghang, the estimated recharges (rates) were 520.4~904.0mm (32.7~61.8%) and 447.4~633.4mm (24.0~45.1%), respectively. The developed model can be suggested as an efficient and precise method to estimate daily based groundwater recharge by using groundwater level data.
