Abstract

In this study, assessment of vulnerability in the management of spatio-temporal groundwater resources considering the surface waterground water interactions was conducted in administrative districts of mountainous regions in Korea. Mountainous regions were classified into four regions and spatial groundwater resources management vulnerability assessment criteria were selected to consider the surface water-ground water interactions. Paju in the central mountainous region, Gapyeongin the mountains region, Gurye in the southwestern mountainous region, and Yangsan in the southeastern mountainous region were selected as a result of the selection of vulnerable area for groundwater resources management. Assessment of the Monthly vulnerability to groundwater resource management due to changes in groundwater levels and infiltration was carried out in the selected areas. As a result of monthly vulnerability to groundwater resources management, December ~ Feburary was assessed as vulnerable to groundwater resource management. The results of this study are expected to contribute to the more efficient groundwater resource management measures by administrative district

본 연구에서는 국내 내륙산간지역의 행정구역을 대상으로 지표수-지하수연계를 고려한 시공간적 지하수자원 관리 취약성 평가를 수행하였다. 내륙산간지역을 4개 산지권역으로 구분하고 지표수-지하수 연계를 고려할 수 있는 공간적 지하수자원 관리 취약성 평가 지표를 선정하였다. 지하수 자원 관리 취약지역 선정 결과 중부산야권역의 파주시, 산악권역의 가평군, 남서산야권역의 구례군, 남동산야권역의 양산시가 선정되었다. 선정된 지역에 대하여 지하수위 및 침투량의 변동에 따른 월 단위 지하수자원 관리 취약 시기 평가를 수행하였다. 월 단위 지하수자원 관리 취약시기 평가결과 12 ~ 2월이 지하수자원 관리에 취약한 시기로 평가되었다. 본 연구의 결과는 지하수자원 관리 취약 지역과 취약 시기 평가 기법 및 결과를 제공함으로써 행정구역 별 보다 효율적인 지하수자원 관리 방안 도출에 기여할 것으로 기대된다.
