摘要: Floods are a major natural hazard, with vast implications over wide range of socio-economic activities. A harmonized post-flood classification is critical for better understanding this by providing homogeneous flood catalogues future research on triggering mechanisms. We apply severity index (FSI) to damaging floods in Northern Portugal 152-year period (1865–2016) and identify the most areas occurrences. The damage-based post-event assessment tool, which includes five categories ranging from minor flooding (1) catastrophic (5). FSI applied historical database 2318 In Portugal, serious (3) frequent typology, while typically river occurring Douro basin. Overall, occurrences favoured positive phase East Atlantic pattern negative North Oscillation. Furthermore, north-western reveal higher concentrations occurrences, mainly due population density, precipitation values more plain areas. particular, 48% all concentrated Porto Metropolitan Area, city centre nearby riverside River. High-population density heavily urbanized lead greater exposure risk, whereas peripheral municipalities, large agricultural/forested areas, show much lower numbers floods. tool communicate magnitude risk is, therefore, foremost relevance civil protection management.
