Abstract

Radial collector wells are widely used to secure large quantities of water from alluvial aquifers adjacent to rivers, and their application has recently increased in Korea. However, previous studies have mainly focused on groundwater drawdown induced by pumping, while the effects of pumping-cycle variations under actual operating conditions have received relatively little attention. This study quantitatively evaluated the effects of pumping cycles on groundwater-level fluctuations in an alluvial aquifer near a river. A three-dimensional groundwater-flow model was developed and calibrated using available hydrogeologic data and observed groundwater levels. After determining the conductance of a radial collector well corresponding to a target pumping rate of 500m³/d, predictive simulations were performed under three operating scenarios: (1) continuous pumping, (2) pumping followed by shutdown periods, and (3) intermittent pumping with daily shutdown periods. The results showed that most groundwater-level recovery occurred within the first 1–2 days after pumping cessation. Under intermittent-pumping conditions, a clear trade-off was observed between pumping yield and water-level recovery. In addition, the extent of influence and the maximum drawdown varied considerably depending on the pumping cycle, even when the same target pumping rate was assumed. These findings suggest that the assessment and operation of radial collector wells should consider pumping cycles as well as pumping rates, and provide a quantitative basis for developing efficient operational strategies.

방사상집수정은 하천 인근 충적대수층에서 대량의 수자원을 확보할 수 있는 시설로, 최근 국내에서도 적용 사례가 증가하고 있다. 그러나 기존 연구는 주로 취수량에 따른 수위 강하에 초점을 두고 있으며, 실제 운용 조건에서의 취수 주기 변화가 지하수위에 미치는 영향에 대한 연구는 부족한 실정이다. 본 연구에서는 방사상집수정의 취수 주기 변화가 하천 인근 충적대수층의 지하수위 변동에 미치는 영향을 정량적으로 평가하고자 하였다. 이를 위해 연구지역의 수리지질 자료를 바탕으로 3차원 지하수 유동 수치모형을 구축·보정한 후, 목표 취수량(500 m³/d)에 대응하는 집수정의 전도계수를 산정하고, 연속 취수, 취수 후 가동 중지, 일중 간헐 취수 조건에 대한 예측모의를 수행하였다. 모의 결과, 가동 중지에 따른 수위 회복은 초기 1~2일 동안 대부분 발생하는 것으로 나타났으며, 일중 간헐 취수 조건에서는 취수량 확보와 수위 회복 사이에 명확한 상충관계(trade-off)가 존재하는 것으로 나타났다. 또한 동일한 목표 취수량을 가정하더라도 운영 주기에 따라 영향 범위와 최대 수위 강하가 달라질 수 있음을 확인하였다. 본 연구 결과는 방사상집수정의 영향 평가 및 운영 전략 수립 시 취수량뿐 아니라 취수 주기를 함께 고려해야 함을 시사한다.
