Method for mitigating seawater intrusion by using seawater injection
Provided is a method for reducing seawater infiltration. According to one embodiment of the present invention, as the method for reducing seawater infiltration in a ground where an aquifer having the seawater-freshwater interface is formed, the method for reducing seawater infiltration of the present invention comprises the following steps of: installing an injection well having a predetermined screen height (s) and a predetermined injection depth (d) at a point spaced apart from a coast by a predetermined distance (L1) inland; injecting a seawater by a predetermined injection amount (Q) into the aquifer through the injection well; and forming an upper seawater region around the injection well by seawater injection. The upper seawater region is a region filled with the seawater in the aquifer above the aquifer.
본 발명의 일 실시예에 따르면, 해수-담수 경계면을 갖는 대수층이 형성된 지반에서의 해수침투 저감을 위한 방법으로서, 해안에서 내륙으로 소정 거리(L1) 이격된 지점에 소정 스크린 높이(s)를 갖는 주입관정을 소정 주입깊이(d)로 설치하는 단계; 상기 주입관정을 통해 대수층 내부로 해수를 소정 주입량(Q)만큼 주입하는 단계; 및 상기 해수 주입에 의해 상기 주입관정 주위에 상부 해수 영역을 형성하는 단계;를 포함하고, 상기 상부 해수 영역은 대수층 내에서 대수층 상부에 해수로 채워지는 영역인 것을 특징으로 하는 해수침투 저감 방법을 제공한다.
