초록

식생/모래기반 자연해빈에서의 파랑, 조석, 강우조건에 의한 지하수위 변동은 식생 환경과 밀접한 관련이 있으며 이는 식생 발달 및 지반 안정화에 크게 영향을 주는 요소이다. 본 연구는 낙동강 하구역의 사주섬 중 최서측에 위치하는 진우도를 대상으로 실험구를 구축한 후 해안선의 법선 방향으로 관측점 5곳을 선정하여 2012년 3월부터 2014년 9월까지(약 799일간) 관측된 수온, 전기전도도, 압력값을 이용하여 지하수위 변동해석을 하였다. 지하수위의 수온, 염분, 수위 변동과 조위, 파랑, 강수량 등의 외력조건과의 시계열 분석 및 상관분석을 통하여, 소상대 정점에서는 파랑 및 조위의 영향, 식생 및 모래지반 정점에서는 강수량 및 조위의 영향을 크게 받음을 알 수 있었다. 고파랑 내습시 관측점간의 지하수위 및 전기전도도의 공간적 거동을 살펴본 결과 Sand dune 및 Vegetation zone이 시작되는 인근에서 담수층과 해수층의 천이 영역(Transition zone)이 존재하였다.

The variation of groundwater by wave, tide and precipitation conditions is closely related to the vegetation environment at the natural vegetation and sandy based beach, and it has a significant impact on the vegetation development and ground stabilization. In this study, the water temperature, electrical conductivity, and pressure were monitored at five observational stations normal to the Jinu-do(Island) shoreline of Nakdong river estuary from March 2012 to September 2014 (approximately 799 days) with the aim of measuring the variation in groundwater-table characteristics. The purpose of the study was to identify factors (tide, wave etc.) affecting groundwater-table variation using time series and correlation analysis, and to record spatial variations in the groundwater level and electrical conductivity as a result of storm events. The observational station in the intertidal zone was strongly affected by wave period and tide level. During the storm period, the groundwater-table and electrical conductivity were stabilized at the edge of sand dunes, vegetation, and areas of transition between freshwater and seawater.
