Abstract

시간평균된 해안의 지하수위는 내륙쪽에 강우가 없는 경우에도 평균해수면 (Mean Sea Level)보다 1내지 2미터 정도 높은 것으로 관측되었다. 이러한 해안의 지하수위상승현상은 주로 파랑과 조석의 작용에 의해 나타난다. 본 연구에서는 지하수위상승에 미치는 조석 및 파랑의 효과를 현장관측결과를 통해 정량적으로 보여주었으며, 또한 이들 각각의 작용에 기인한 지하수위상승에 대한 해석해 및 최근 이론들을 제시하였다. 특히, 최근 지하수의 수리학적 모델링에 관한 연구에서 파랑의 침투 (wave runup infiltration)효과의 중요성이 강조되었는 바, 본 연구를 통해 종래에 보고된 바 없는 swash zone (shoreline과 runup limit사이)에서의 파랑의 침투속도(분포)를 지하수위관측자료를 이용해 간접적으로 산정함으로써 해안의 지하수위예측모델링을 보다 정확히 수행할 수 있으리라 사료된다.
