Abstract

Streamflow responses to irrigation reservoirs and groundwater withdrawals were simulated using the integrated surface-water and groundwater model, SWAT-MODFLOW for the upstream watershed of the Gongdo station located in the Anseong stream. The simulated results indicated that the irrigation water supply from the Gosam and the Geumkwang reservoirs has caused the decrease of 31.2%, 82.5% in drought flows below the reservoirs, respectively, against the natural flow condition. While, at the outlet of the study watershed, the effects of the irrigation reservoirs were insignificant due to the delayed return flows with the decrease of 5.7% in drought flow. Both of the irrigation reservoirs and groundwater withdrawals have reduced the drought flows by 19.2% at the Gongdo station.

본 연구에서는 안성천 공도수위관측소 상류유역에 대해 지표수-지하수 통합모형 SWAT-MODFLOW를 적용하여 농업용 저수지 관개 및 지하수 이용에 따른 하천유출량 변화를 모의하였다. 유역내에 위치한 고삼 및 금광 저수지 직하류부에서는 관개용수 공급으로 인하여 갈수량이 자연 유량 조건에 비해 각각 약 31.2%, 82.5% 만큼 감소하는 것으로 분석되었다. 반면에 유역 출구부에서는 회귀수 영향으로 농업용 저수지 영향이 작게 나타나 5.7% 정도의 갈수량이 감소하였으며, 지하수 양수 영향과의 복합적 영향으로 약 19.2% 만큼 감소하는 것으로 분석되었다.
