해수침투 발생 요인은 무엇인가? | 해안지역에서 해수침투에 의한 지하수 오염은 오래 전부터 심각한 문제로 인식되어 왔으며 이를 해결하기 위해 다양한 분야에서 많은 연구가 활발하게 진행되었다(Shin and Byun, 2010; Chang, 2014). 해수침투는 해수면 변동, 함양량 감소 등의 자연적인 요인과 지하수 사용량 증가, 토지 이용 형태 변화 등의 인위적인 요인에 의해서 발생된다. 특히 최근의 기후변화로 인한 해수면 상승, 강우 패턴의 변화 등의 해수침투를 가속화 시켜 넓은 지역에 영향을 줄 것으로 예상된다(Shim et al. | |
해수침투관측망은 매 시간 어떤 요소들을 측정하는가? | , 2008). 각 관측정에서는 지하수 수위, 수온, 전기전도도를 매 시간 측정하여 서버로 전송하며 측정결과는 매년 보고서로 발행한다. | |
국내 지하수 및 해수침투 관련 관측망에는 어떤 것들이 있는가? | 국내에서는 국가지하수관측망, 보조지하수관측망, 지하수 수질관측망, 해수침투관측망을 운영하고 있으며 이들 관측망으로부터 축적된 자료는 지하수 자원의 관리방안 마련 시기초자료로써 활용되고 있다. 해수침투관측망은 1998년부터 현재까지 지속적으로 설치되어 운영되고 있으며 2014년 말 현재 145개의 관측정이 운영되고 있으며 서해안, 남해안, 동해안에 각각 65, 56, 24개소가 설치되었으며 전라남도(JN), 경상남도(GN), 경기도(GG)에 관측정이 주로 설치되었다 (MAFRA and KRC, 2014)(Fig. |
