This paper describes the methodology of the vulnerability assessment to flooding in anestuarine context and presents the final results for the Tagus River estuary, in the metropoli-tan region of Lisbon (Portugal). Performing a local study adapted to a specific type of hazardposed two initial methodological challenges: the selection of the unit of analysis and theidentification of the pertinent and available variables. Both challenges were addressedassuming that the area to be assessed should also include the units outside the inundatedarea, a buffer zone that would include areas indirectly affected. The application of thestatistical procedures established in the SoVI1 methodology indicate that certain widely usedvariables in vulnerability assessments on smaller scales are inadequate at the statistical blockscale and that specific variables must be defined and integrated to represent more broadly thedimensions of vulnerability related to social assistance, infrastructures and commutability.The extracted principal components identified the vulnerability drivers in the riversideand surrounding areas. These drivers identify the urban context, the family structure, andthe socio-economic condition expressed in terms of housing characteristics, education,mobility and commuting as the dimensions that most differentiate territorial and individuals
