초록

해수침투로 인하여 부존되어 있는 지하수의 염분농도가 높아 방치되고 있는 해안지역 대수층을 활용한 수자원 확보 방안을 제안하였다. 대수층으로 담수를 주입하여 염수를 치환할 수 있는 주입-양수 시스템을 연구하였다. 염수로 포화되어 있는 충적층에서 인공함양 및 회수 기술이 성공하기 위해서는 양수정으로 유입되는 염수를 방지하는 것이 가장 중요한 문제 중의 하나이다. 본 연구에서는 양수정을 염수 침투로부터 방지하기 위한 염수포획관정의 효과를 수치모델링 방법으로 분석하였다. 적절히 설계된 염수포획관정은 담수 양수정을 염수침입으로부터 보호할 수 있음을 제시하였다.

A new method is proposed for water resources using aquifers in coastal areas. These aquifers are generally filled with saline water due to seawater intrusion and consequently being left unutilized. Surface water can be injected into these aquifers and recovered for water quality enhancement and stored water. Injection and pumping wells are used. For this technique to be successful protection of pumping well from seawater intrusion is an essential issue. Salt water pumping can be used to prevent saline water upconing. Numerical analysis demonstrated that a properly designed and executed salt water pumping well can protect a freshwater pumping well from salt water intrusion.
