Abstract

Landslide in Korea occurs generally in summer, and rainfall is a major factor to trigger landslides. This study evaluates the applicability of radar rainfall to estimate landslide occurs locally in mountainous area. Temporal changes in spatial distribution of rainfall is analyzed using radar data, and the characteristics of rainfall in landslide area during the landslide occurred in Inje, July 2006. This study shows radar rainfall field can estimate local landslides more precisely than the rainfall data from ground gauges.

우리나라의 산사태는 여름철 집중호우 시에 주로 발생하며, 강우는 산사태 발생에 결정적 영향을 미치는 요소이다. 본 연구에서는 산악지역에서 국지적으로 발생하는 산사태의 예측을 위한 레이더 강우자료의 활용성을 평가하였다. 2006년 7월에 발생한 인제지역 산사태를 대상으로 레이더 자료를 이용하여 유역내 강우 공간분포의 시간적 변화를 분석하였으며, 산사태 발생지와 산사태 발생 기간에서의 강우특성을 평가하였다. 연구결과 레이더 강우장을 이용하는 것은 기존의 지점강우를 이용하는 방법에 비해 국부적으로 발생할 수 있는 산사태를 정밀하게 예측할 수 있는 것으로 나타났다.
