A Promethee multiple-criteria methodology for combined seismic and hydraulic risk assessment: the case study of Ferrara (Italy)

The purpose of this work is to describe the methodology used for the evaluation of the combined seismic and hydraulic risk of the territory of Ferrara. The Visual PROMETHEE software, based on outranking methods (PROMETHEE methods), was used as a tool for data implementation. In this application the hydraulic and seismic risk have been broken down into their components: probability of occurrence of the flood, seismic hazard (PGA), exposure (land use, strategic buildings, population density) and vulnerability (age of buildings). The result of the analysis made it possible to highlight the areas most affected by the hydraulic-seismic risk (Fig. 1) but also the criteria that most positively and negatively influence the municipalities of Ferrara.
