Abstract

The frequency of localized heavy rain is increasing due to the influence of abnormal climate that is rapidly increasing in recent years. As a result, the difficulty of safe water resource management is increasing and human and material damage is increasing. Various countermeasures are being established to reduce the damage caused by localized heavy rain, but small-scale mountain catchments are experiencing many difficulties due to the lack of a basic plan. Therefore in this study the risk of flooding was evaluated using the rainfall-runoff model in the Yu-pyeong catchment national park among national parks in Korea. As a result of the analysis, it was simulated that flooding occurred in the Yu-pyeong catchment of Mt. Jirisan when rainfall with a recurrence frequency of 50 years or more occurred, and it was confirmed that there was a high risk of structures, safety facilities and trails.

최근 급증하는 이상기후의 영향으로 인하여 국지성 호우의 발생 빈도가 증가하고 있다. 이로 인하여 안전한 수자원 관리의 어려움이 증가하고 있으며, 인적 및 물적 피해가 늘어나고 있다. 국지성 호우로 인한 피해를 저감하기 위하여 다양한 대책방안을 수립하고 있으나 소규모 산지유역은 기본계획 수립 등의 부재로 인하여 어려움을 겪고 있다. 본 연구에서는 우리나라 국립공원 중 지리산 국립공원 중 유평유역을 대상으로 강우-유출모형을 활용한 침수 위험도 평가를 수행하였다. 지리산 유평유역은 재현빈도 50년 이상의 강우 발생 시, 홍수가 발생하는 것으로 모의 되었으며, 수공 구조물, 안전 시설물 및 탐방로에 대하여 위험성이 높게 나타나는 것을 확인하였다.
