Estimation of groundwater hydrologic cycle pattern is one of the most critical issues in sustainable management of groundwater resources in coastal area. This study estimated groundwater percolation by using the water balance methodology and hydrogeological characteristics of land use and soil. Evap...

방사성폐기물 처분시설 부지에 대해서는 지하수 유동 특성을 명확히 규명해야 하는 이유? | 지하수는 폐기물 내부에서 오염된 방사성 핵종의 용해, 이동, 및 운반 매개체로서 매우 중요하기 때문에 방사성폐기물 처분시설 부지에 대해서는 지하수 유동 특성을 명확히 규명하는 것이 필수적이다[1]. 지하수 유동 특성을 조절하는 인자들로는 퇴적층의 조직, 간극 부피, 지질 구조, 지질 특성 등이 포함된다[2, 3]. | |
지하수 유동 특성을 조절하는 인자는? | 지하수는 폐기물 내부에서 오염된 방사성 핵종의 용해, 이동, 및 운반 매개체로서 매우 중요하기 때문에 방사성폐기물 처분시설 부지에 대해서는 지하수 유동 특성을 명확히 규명하는 것이 필수적이다[1]. 지하수 유동 특성을 조절하는 인자들로는 퇴적층의 조직, 간극 부피, 지질 구조, 지질 특성 등이 포함된다[2, 3]. 그러나, 특정한 면적 영역의 경우, 지하수 유동은 수리수문학적 순환의 한 부분으로 고려되어 해석될 수 있으며, 강우량, 토양 함수 특성, 하천 유출량, 온도, 토지이용도 등의 지형적, 지질학적, 기후적인 조건을 반영한 지하수 순환 특성으로 결정될 수 있다[4]. | |
증발산은 기상학적 인자 이외에도 무엇에 영향을 받는가 | 증발산(evapotranspiration)은 수면으로부터의 증발(evaporation)과 식물로부터의 증산(transpiration)을 합한 값이며, 수분이 기체 상태로 대기에 환원되는 모든 것을 포함한 것이다. 이는 기상학적 인자 이외에도, 식물의 종류, 색깔의 농도, 식물의 밀도, 성장 속도, 잎 표면의 크기 등의 식물 요소뿐만 아니라 토양의 공극률, 수리전도도, 입자의 크기, 토양의 함수율 등에 직접적으로 영향을 받는 인자이다[26]. 증발산량은 직접적인 측정이나 간접적인 계산에 의해서 결정할 수 있다. |
