Abstract

Recently, the damages by typhoons and heavy rains are increasing due to the climate change. However, we are still vulnerable to inundation disaster due to various causes such as poor physical flood control and lacks of disaster and safety management. Therefore, it is necessary to establish systems to ensure safety and prepare practical countermeasures that can minimize damage when an inundation occurs, thereby minimizing economic loss and casualty. In this study, hydrodynamic inundation modelings were implemented to analyze the "Noryangjin reservoir inundation accident" and "Choryang No. 1 underground road inundation accident." and spatial risk was assessed by a quantitative hazard index. In addition, cause and effect diagrams were provided to present the risk causes in terms of physical and managemental aspects.

최근 기후변화로 인해 태풍과 호우 피해가 증가하고 있으나 물리적인 침수대책과 재난대응 안전관리가 여전히 미흡한 실정이다. 따라서 안전 확보를 위한 대응체계를 마련하고, 침수 발생 시 피해를 최소화할 수 있는 실용적인 방안을 확보함으로써 경제적인 손실과 인명피해를 최소화하는 방안 마련이 필요하다. 본 연구에서는 '노량진 배수지 수몰 사고', '초량제1지하차도 침수사고'에 대한 동수역학 모의를 수행하고 침수양상을 해석하였으며, 침수위험도 정량화 지수를 이용하여 공간적 위험도를 산정하였다. 또한 특성요인도를 통해 침수사고에 대한 물리적, 관리적 원인을 체계적으로 제시하였다.
