AB [EN] To increase the resilience of communities against floods, it is necessary to develop method-ologies to estimate the vulnerability. The concept of vulnerability is multidimensional, butmost flood vulnerability studies have focused only on the social approach. Nevertheless, inrecent years, following seismic analysis, the physical point of view has increased its rele-vance. Therefore, the present study proposes a methodology to map the flood physical vul-nerability and applies it using an index at urban parcel scale for a medium-sized town (Pon-ferrada, Spain). This index is based on multiple indicators fed by geographical open-sourcedata, once they have been normalized and combined with different weights extracted froman Analytic Hierarchic Process. The results show a raster map of the physical vulnerabilityindex that facilitates future emergency and flood risk management to diminish potentialdamages. A total of 22.7% of the urban parcels in the studied town present an index valuehigher than 0.4, which is considered highly vulnerable. The location of these urban par-cels would have passed unnoticed without the use of open governmental datasets, when anaverage value would have been calculated for the overall municipality. Moreover, the build-ing percentage covered by water was the most influential indicator in the study area, wherethe simulated flood was generated by an alleged dam break. The study exceeds the spatialconstraints of collecting this type of data by direct interviews with inhabitants and allowsfor working with larger areas, identifying the physical buildings and infrastructure differ-ences among the urban parcels
