La valutazione della vulnerabilità idraulica in un’area di pianura alluvionale della provincia di Padova, mediante "Multicriteria Evaluation"

Multi Criteria Evaluation of Flood Vulnerability in a Sector of Alluvial Plain in the Province of Padua. – This paper regards the application of the “Multi Criteria Evaluation” (MCE) technique to the GIS mapping of the flooding vulnerability of the alluvial plain near Vighizzolo d’Este, related to overbank flooding of the Agno-Guà- Frassine-Santa Caterina river. MCE relies on the accurate definition of the factors which contribute to the final elaboration. The geomorphology and geopedology of the study area have been defined through DEM elaboration, remote sensing and field survey. The spatial distribution of buildings and infrastructures, crucial to vulnerability assessment, has been derived from 1:5.000 topographic maps. The integrated data elaboration has been carried out using the MCE module of the GIS software IDRISI32TM. A detailed map of the different degrees of flooding vulnerability in the study area has been produced.
