Abstract

홍수방어에 대한 과거의 연구들은 대부분 대규모 하천 유역에 집중되어왔으나, 최근 경제력의 향상을 통한 산악지역으로의 레져영역의 확대는 돌발홍수 발생에 대비한 추가적인 방재활동의 필요성을 증대시키고 있다. 따라서 본 연구에서는 돌발홍수로 인한 인명 및 재산 피해를 최소화하기 위하여 다양한 지표들을 고려하여 산지유역에서의 돌발홍수 발생 위험을 평가하기 위한 기법을 제시하였다. 이를 위해 본 연구에서는 돌발홍수 위험지역을 평가하기 위하여 지역특성, 강우특성 및 지형특성을 평가지표로서 선정하였으며, 이들 요소들의 특성을 평가하여 돌발홍수 경보 시스템 설치를 위한 적정 지점을 평가 및 선정하는 기법을 제안하였다. 제안된 평가 기법은 봉화군에 적용되었으며, 이를 통하여 제안된 기법의 적용 과정을 설명하였다. Most prevention efforts have been made for relatively large watersheds near to channel flow. However, as economical development and the expansion of leisure areas to mountainous region, human casualty by flash flood occurs frequently, requiring additional prevention activity. Therefore, to minimize the damage of human lives and property by flash flood, we develop a methodology to assess the risk of flash flood occurrence for mountainous areas considering various factors involving it. For accomplishing the task, we selected the assessment indexes such as the characteristics of region, rainfall and land in mountainous area. And considering the characteristics of these indexes, the assessment method was suggested to assess and select the reasonable points for flash flood warning system. The suggested method was applied to BongHwa region and the application process of this method was explained.
