Flood maps of Rainfall Event of November 2023 in Tuscany, Italy

<p>To support the evaluation of the Digital Twin system of the SCORE project, we defined an improved flood mapping procedure based on high-resolution SAR data to obtain flood maps of hystorical events, which will be used as validation reference for the Digital Twin outputs maps.&nbsp; We analyzed a recent significant flood event occurred in the densely populated Florence-Prato-Pistoia plain area (Tuscany, Italy) between 2 and 5 November, 2023.&nbsp; The estimated total losses for the entire region are at 1890 million euros.<br>The available images used for the the flood event analysis were acquired by COSMO-SkyMed Second Generation on 5 November 2023 in dual polarization HH-HV and by COSMO-SkyMed First Generation on 6 November 2023 in HH polarization. The flood mapping procedure, based on clustering and fuzzy logic approach, has been applied to Florence-Prato-Pistoia plain study area in rural areas and, when cross-polarization data are available, in urban areas. The dataset includes two images: the first one (named flood_05.11.2023_compressed.tif) is a map of the flood extent in rural areas of the region of interest and urban areas of Pistoia, Prato, Sesto Fiorentino and Firenze on 5 November; the second one (named flood_06.11.2023_compressed.tif) is a map of the flood extent in rural areas of the region of interest on 6 November.</p> <div> <div> <div> <div>&nbsp;</div> </div> </div> </div> <p>&nbsp;</p>
