초록

베트남의 도시들은 지리적 특성으로 인해 기후변화에 따른 홍수 위험성이 높은 상황인데, 빠르게 도시지역이 확장됨에 따라 홍수위험성은 더욱 가중되고 있다. 본 연구에서는 도시확장강도지수를 활용하여 지난 10년간(2007년-2017년) 베트남 국가차원에서의 도시확장 추세를 확인한 후, 기후변화 영향이 크고 확장속도가 빠른 지역으로서 후에시를 선정하여 홍수발생가능성을 확인하였다. 그 결과 홍강델타, 메콩델타, 해안지역의 주요 도시 주변으로 확장되었으며, 후에시의 경우 확장속도가 빠른 지역일수록 예상침수면적이 높은 것으로 나타났다. 이는 향후에 홍수재해 위험성이 더욱 커질 수 있음을 의미한다. 재해취약성분석 제도 등 국내의 도시방재정책은 베트남 급성장지역에서 기후변화를 고려한 도시계획 수립 시 도움이 될 것이다.

Vietnamese cities have a high risk of flooding under climate change due to their geographical characteristics. In this situation, the urban area is expanding with rapid growth of urban population. However, the risk of flooding is increasing due to the increase in impermeable areas and insufficient infrastructure. This study analyzed the urban expansion trend at the national level in Vietnam for the past 10 years (2007-2017) by using the Urban Expansion Intensity Index. Also, this study selected Hue City as a region with a large impact of climate change and a rapid expansion and found the possibility of flooding in the urban expansion area. The result showed that cities have been expanded around major cities in the Red River Delta, Mekong Delta, and coastal areas. In the case of Hue City, the area with fast expansion rate has a higher expected flood area. It implies that the risk of flood disasters may increase if the urabn expansion is carried out without disaster prevention measures. It is expected that Korean urban disaster prevention policies such as urban climate change disaster vulnerability analysis system will be helpful in establishing urban plans considering climate change in the fast growing regions such as Vietnam.
