| Summary: | International audience This paper proposes a vulnerability assessment of the Yakutsk areas exposed to the spring breakup flood. The approach is based on the use of remote sensing and a GIS’s multi-criteria analysis. Before assessing the vulnerability, potential flood-prone areas have been model with data from Global Digital Elevation Model (GDEM) ASTER v.2 (USGS/METI) and, next, correlated with the categorisation of the urban areas at risk of flooding by image processing with EO-1 ALI satellite images. The methodology developed permitted to build a typology of vulnerable areas and consequently to supply information and data to assess with criteria the vulnerability in several dimensions. In this study, the multi-criteria analysis evaluates the vulnerability in three component and as a whole. Results of this work are focused on the geographic understanding of the vulnerability to the spring breakup flood risk than on the consequences.
