초록

본 연구에서는 대상유역인 경안천 유역 (유역면적 $260km^2$)에 대한 지하수 함양량 추정을 위해, 완전 분포형 모형인 MIKE SHE를 적용하였다. 모형 입력자료로서 DEM 토지이용도, 정밀토양도 등과 같은 GIS 자료를 구축하고, 기상자료를 이용하여 증발산 입력자료를 생성하였다. 유역 최종 출구점인 경안 수위표 지점에서의 유출자료를 활용하여 모형 보정과 검증을 수행한 결과, 관측치의 경향을 잘 모의하는 것으로 나타났으며, 유역내 운영되고 있는 마평 지하수위 관측소의 관측지하수위와 모의치를 비교한 결과도 매우 양호하게 나타났다. 모형을 이용하여 대상유역에 대한 연간 지하수 함양량을 산정하고, 기존의 감수곡선법에 의해 계산된 값과 비교한 결과 비슷한 모의값을 보였다. 결론적으로 모형을 통한 지하수위 모의 및 함양량 모의에 신뢰성이 높게 나타났으며, 함양량의 시공간적인 분포 특성 파악에 유의하게 활용될 수 있을 것으로 생각된다.

To estimate the groundwater recharge, the fully distributed parameter based model, MIKE SHE was applied to the Gyeongan-cheon watershed which is one of the tributaries of Han River Basin, and covers approximately $260km^2$ with about 49 km main stream length. To set up the model, spatial data such as topography, land use, soil, and meteorological data were compiled, and grid size of 200m was applied considering computer ability and reliability of the results. The model was calibrated and validated using a split sample procedure against 4-year daily stream flows at the outlet of the watershed. Statistical criteria for the calibration and validation results indicated a good agreement between the simulated and observed stream flows. The annual recharges calculated from the model were compared with the values from the conventional groundwater recession curve method, and the simulated groundwater levels were compared with the observed values. As a result, it was concluded that the model could reasonably simulate the groundwater level and recharge, and could be a useful tool for estimating spatially/temporally the groundwater recharges, and enhancing the analysis of the watershed water cycle.
