Abstract

An analytical model was developed to estimate the stream depletion due to cyclic groundwater pumping by extending the Hunt’s analytical solution which was derived from considering the hydraulic characteristics of the aquifer and the streambed. The model was applied to analyze the long-term effects of groundwater pumping on stream depletion during irrigation season. For the case of a total of 1,500 conditions according to various aquifer and streambed hydraulic characteristics and stream-well distance, the stream depletion due to cyclic groundwater pumping for 10 years was calculated and the results were graphically represented. Especially, the maximum and average stream depletion rates were calculated and compared with the results for continuous groundwater pumping. Furthermore, considering both stream depletion and return flow rates, the limit hydraulic condition that minimizes the influence of groundwater pumping for irrigation water supply on stream depletion was suggested.

대수층과 하상의 수리특성을 고려하여 유도된 Hunt 해석해에 영상정과 중첩원리를 적용하여 양수 및 중단을 반복하는 주기적 지하수 양수로 인한 하천수 감소량을 산정할 수 있는 해석적 모형을 개발하고, 이를 활용하여 관개기 지하수 양수에 따른 하천수량에 미치는 장기 영향을 분석하였다. 대수층과 하상의 다양한 수리특성값과 하천-관정 이격거리 조합에 따라 총 1,500 가지 조건에 대해 10년 양수시 하천수 감소량을 산정하고 그 결과를 도시적으로 나타내었으며, 특히 양수기간동안 최대 및 평균 하천수 감소율의 거동 특성을 연속적인 양수의 결과와 비교, 분석하였다. 또한, 하천수 감소율과 농업용수 회귀율을 함께 고려하여 하천수량 측면에서 관개기 지하수 양수 영향을 최소화할 수 있는 한계수리조건을 제시하였다.
