Abstract
Flood risk is a direct interaction between climate change and society. In the context of increasing global flood risk, developing a risk assessment model that can effectively support disaster risk management strategies and policies is essential. This is especially relevant in the case of World Heritage Sites in terms of their socio-economic value. Although there has been a large amount of conservation of literature on the topic of world heritage and disaster mitigation on these sites, the applicability of studies is often limited to single properties or locations. This study proposes a research model to conduct quantitative and semi-quantitative inundation risk assessments for immovable heritage sites. The selection and calculation of a risk index can be used to provide a preliminary assessment of the flood inundation risk for a World Heritage Site. This research is illustrated through an app for Hoi An City. This case study is used to discuss various issues related to data requirements, availability and reliability.
