Resumo(s)
Around 45% of natural hazards reported worldwide are related to floods, andcurrent indications show that exposure to floods and inherent losses will keepescalating. Historic centres are particularly vulnerable in this context due tothe structural and material characteristics of the buildings and because theyembrace social and cultural values that must be safeguarded. This article aimsto contribute to this research area by presenting and discussing the applicationof an index-based methodology specifically tailored to assess flood risk in his-toric urban centres. The historic city centre of Tomar, Portugal, an area thatencompasses over 500 buildings and has a rich history of floods, is used hereas a case study. Vulnerability data resulting from the application of the vulner-ability assessment approach are then combined with flood hazard—that is,water velocity and depth obtained from flood peaks estimated for 20- and100-year periods of return—and used to identify the buildings at risk. Finally,a set of depth-damage curves is derived and used here to carry out a cost–benefit analysis for different flood adaptation measures.
