Abstract

This study was to evaluate the stream depletion from groundwater pumping in shallow aquifer using the Hunt's analytical solution (2009) which considers a two-layer leaky aquifer-stream system. From the total 2,187 cases of simulations with combinations of various aquifer and stream properties, the streamflow depletion rates divided by the groundwater pumping rate showed the low values when the stream depletion factor (SDF) is higher than 1,000-10,000, and was more sensitive to the aquitard hydraulic conductivity than the streambed hydraulic conductivity. The comparison of the Hunt's solution (2009) with the Hunt's solution (1999) of a single layer aquifer indicated that the maximum difference between the dimensionless stream depletions calculated by using both solutions is above 0.3, and the stream depletion is significantly affected by the hydraulic properties of the $2^{nd}$ layer as the SDF of the first layer increases. The Hunt's solution (2009) was applied to the real shallow groundwater well that is located in Chunju-Si, and the results revealed that the groundwater pumping has significant effects on streamflow in a short period of time, showing that the dimensionless stream depletion exceeds 0.8 within a few days. It was also found that the shallow groundwater pumping effects on stream depletion are highly dependent on the stream-well distance for the locations with high hydraulic diffusivity of $1^{st}$ layer and low vertical leakance between $1^{st}$ and $2^{nd}$ layers.

본 연구에서는 2층 누수대수층-하천 시스템에 관한 Hunt (2009)의 해석해를 이용하여 천부대수층 지하수 양수가 하천수량에 미치는 영향을 분석하였다. 대수층 및 하상의 수리특성 조건에 따라 총 2,187가지 경우의 수에 대해서 양수량 대비 하천수 감소량을 산정한 결과 하천고갈인자가 1,000-10,000 보다 큰 경우에 비교적 작은 값을 나타내었으며, 하천바닥층 수리전도도보다는 1, 2층간 반대수층의 수리전도도 크기에 상대적으로 민감한 반응을 보였다. 또한, Hunt (1999)의 해석해로 산정한 하천수 감소비에 비해 최대 0.3을 넘는 차이가 발생하는 등 1층의 하천고갈인자가 큰 경우에는 2층의 수리특성치에 큰 영향을 받는 것으로 분석되었다. 실제로 충주시에 위치한 임의의 천부지하수 관정에 적용하여 양수 경과시간에 따른 하천수 감소비를 산정한 결과 수일 내로 0.8을 초과하여 하천수에 미치는 영향이 단기간에 크게 발생하였으며, 또한 누수계수가 작고 천부대수층의 수리확산계수가 큰 지역에서는 하천-관정 이격거리가 하천수 감소량 크기를 결정하는데 지배적인 인자인 것으로 분석되었다.
