Susceptibility assessment of climate change-induced geo-disasters in South Korea

C limate change adaptation in infrastructure sector has been great attention in recent years, though there is a difficulty in
identifing the most suitable and efficient adaptation options. This paper proposes a framework for assessing the costs and
benefits of infrastructure adaptation for the geo-disasters such as landslide and debris flow. In the Asia-Pacific region, there
is an evidence of prominent increases in the intensity and/or frequency of extreme events under intense rainfall and severe
storms, which trigger more geo-disasters on infrastructure. In this paper, a case study was carried out in Umyeonsan (Mt.),
South Korea. Three Representative Concentration Pathways climate scenarios are utilized to estimate the cost of future damage
and the conditions of the assessed infrastructure. Susceptibility assessment of geo-disaters were conducted by using physically-
based models, YS-slope and ABAQUS/CEL. The climate change scenario was scaled down for Korean circumstances, and
then, applied to anayze geo-disaters. It is shown that landslide hazard and debris flow damage are highly influuenced by
climate change scenario. Based on this result, possible cost benefit is estimated, and a conceptual methodology for susceptibilty
assessment of rainfall-induced geo-disasters is suggested. It is expected to guide decision making in prioritizing the most cost-
effective adaptation strategies for infrastructure.
