Juliana Siqueira-Gay, Mariana Abrantes Giannotti, Diego Bogado Tomasiello


Based on the recent literature relating transport service level and social exclusion, as well as perceptions about the capacity of the population to cope with the occurrence of fl ood events, this paper identifi ed the spatial pattern related to fl ood risk and accessibility to urban facilities.
