Abstract

Climate change has emerged as a social issue, and efforts have been made to overcome it in various ways. However, climate change due to global warming is likely to accelerate further than we expected, and the associated damage is also likely to increase. This tendency is expected to continue in the future, leading to difficulties for the existing water resource management system based on historical data. The precipitation in 2020 caused property damage and loss of life due to the extreme rainfall exceeding the design rainfall with the very unusual prolonged rainy days. With this 2020 flood, we should no longer be passive in managing flood risk due to uncertainties in climate change.

기후변화는 국내외의 다양한 분야에서 사회적 이슈로 대두되고 있으며, 이를 극복하기 위한 노력이 다각도로 진행되고 있다. 하지만 지구온난화에 따른 기후변화는 우리의 예상보다 더욱 빠르게 변화하고 있어, 그에 따른 피해도 증가하고 있는 추세이다. 이러한 기후변화 경향은 앞으로도 지속될 것으로 전망되며, 이로 인해 과거자료에 근거하여 이루어지는 기존의 보수적인 수자원 관리 체계는 기후변화로 인해 위험도를 가중시킬 수 있는 개연성이 있다. 2020년의 강우는 매우 이례적인 장기간의 장마와 설계강우량을 초과하는 강우량으로 인해 큰 재산 및 인명 피해를 야기시켰다. 이번 2020년 대홍수를 기점으로 더 이상 기후변화의 불확실성을 이유로 홍수문제를 포함한 수자원관리에 소극적이고 방어적인 대응 및 대비는 지양하고 보다 실행력 있고 미래 기상정보를 적극적으로 활용할 수 있는 현업체계의 도입을 위한 논의가 필수적으로 요구되어야 한다.
