Abstract

This study is a follow-up study of vulnerable areas according to the vulnerability assessment of groundwater resource management in Korea. In this study, an optimal operation plan for groundwater resource management was proposed for areas vulnerable to groundwater resource management in Korea derived from previous studies. Prior to presenting the optimal operation plan for groundwater resource management, this study grasped the current status of changes in groundwater level and seawater penetration area for vulnerable areas using MODFLOW, a groundwater flow analysis program. As a result of the analysis using basic data for 10 years from 2009 to 2018, the groundwater level fell and the sea infiltration area increased. The final purpose of this study, the optimal operation plan for groundwater resource management, was selected as a total of four alternatives that can be expected to have positive effects to increase groundwater level and reduce seawater penetration. As a result of analyzing the amount of change in groundwater level and seawater penetration by applying the selected optimal operation plan, positive effects were found in all methods. It is expected that the optimal operation plan for groundwater resource management proposed in this study will be applied not only to vulnerable areas of groundwater resources in Korea but also to areas requiring development to establish efficient groundwater resource management measures.

본 연구는 국내 지하수자원 관리 취약성 평가에 따른 취약 지역 연구의 후속 연구이다. 이번 연구에서는 선행연구에서 도출해낸 국내 지하수자원관리 취약 지역에 대하여 지하수자원 관리 최적 운영 방안을 제시하였다. 본 연구는 지하수자원 관리 최적 운영 방안을 제시하기에 앞서 취약 지역을 대상으로 지하수위 변화 및 해수침투 면적 변화의 현황을 지하수 유동 해석 프로그램인 MODFLOW를 이용하여 파악하였다. 2009년부터 2018년 10년간의 기초 자료를 이용한 분석 결과 지하수위는 하강하고 해수침투 면적은 증가하였다. 본 연구의 최종 목적인 지하수자원 관리 최적 운영 방안은 지하수위 상승과 해수침투 저감을 위해 긍정적인 효과를 기대할 수 있는 대안들을 조합하여 총 4가지로 선정하였다. 선정된 최적 운영 방안을 적용하여 지하수위와 해수침투의 변화량을 분석한 결과 모든 방안에서 긍정적인 효과가 나타났다. 본 연구에서 제시하는 지하수자원 관리 최적 운영 방안은 국내 지하수자원 취약 지역뿐만 아니라 개발이 필요한 지역에도 적용하여 효율적인 지하수자원 관리 대책 수립에 근거가 될 것을 기대한다.
