Modelling Flood Risk in Central Viet Nam: A Quantitative Assessment of Adaptation Benefits in the Huong River Catchment - VN
Viet Nam's extensive coastline and densely populated riverine and coastal regions render it particularly susceptible to flood hazards. The centrally governed city of Hue, formerly part of Thua-Thien Hue province, exemplifies this vulnerability. The Huong River catchment, integral to Hue's urban and peri-urban landscapes, frequently experiences flooding events that adversely affect communities, infrastructure and ecosystems, and thus serves as the research area of this analysis.
This report provides a quantitative perspective on flood risks in the Huong River catchment, utilizing the open-source CLIMADA modelling platform to model hazard, exposure and vulnerability data, as well as a specifically developed random forest model, e.g. for building classification. It complements the assessment detailed in the report Flood Risks in Hue, Central Viet Nam: An assessment of flood hazards, exposures, vulnerabilities, root causes and impacts (Sett et al. 2025). Together, these analyses, as well as other outcomes of the FloodAdaptVN project, offer a comprehensive understanding of flood risk dynamics in the region, supporting the development of targeted, sustainable flood risk management and adaptation strategies at the catchment level.
