Abstract

Rainfall infiltration through the unsaturated zone is influenced by a range of factors including topography, geology, soil, rainfall intensity, temperature and vegetation; the actual infiltration varies largely in time and space. The infiltration capacity of soil is a critical factor in identifying groundwater recharge and leakage of surface water. It may differ depending on soil types and geological features of a particular basin or territory as well as on the usage of the land. This study was conducted in forest and farmland region of the mid-mountain area (EL. 50~300 m) of Jeju Island to test soil infiltration capacity of the area where rainfall contributes to groundwater. Results were analyzed using the four soil group classification methods presented by Jeong et al. (1995) and NAS (2007) to discover that the method offered by NAS (2007) is more reliable in the mid-mountain area of Jeju Island. The study compares and reviews the existing classification methods using the results of infiltration capacity tests executed on different soil groups throughout the whole region of the Jeju mid-mountain area. It is expected that this work will serve as a guideline for evaluating surface water recharge and hydraulic characteristics of Jeju Island.

강수가 불포화대를 통해 침투하는데 관여되는 요소는 지형, 지질, 토성, 강우강도, 기온, 식생 등의 영향을 복합적으로 받으므로 실제 발생하는 침투현상은 시 ‧ 공간적으로 큰 차이를 보인다. 토양의 침투능력은 지하수의 함양량 및 지표수의 이동 유출을 파악하는데 중요한 인자이고, 특정 유역 또는 지역에 따른 토성과 지질의 유형 및 토지이용형태에 따라 침투능이 다르게 나타난다. 본 연구에서는 제주도 중산간 지역인 EL. 50~300 m 임야 및 농경지를 대상으로 강우가 토양을 통해 지하수로 함양되는 중산간 지역에서 토양침투시험을 실시하였으며, 분석결과를 이용하여 Jeong et al.(1995) 및 NAS(2007)가 제시한 4개의 토양군에 따른 투수성을 분석한 결과 NAS(2007) 분류법이 제주도 중산간 지역에서는 신뢰성이 높은 것으로 분석되었다. 본 연구에서 제주도 중산간 전 지역에 대한 토양별 침투실험을 실시하여 기존의 분류 방법과 비교, 검토함으로서, 향후 제주도의 지표 함양량 평가, 수리특성 평가 시 참고 지침이 될 것으로 기대한다.
