Cartography of Vulnerabilities - Battenti P3 - Tr 10 years

The dataset 'Battenti P3 - Tr = 10 years - areas' is a classification of the expected wings in the perimeter areas as P3 pursuant to Legislative Decree 49/2010 - Floods Directive 2007/60. For the beach it is suggested to use, however, the information level 'bathing beach' which is more cautious. The cartography of the hinges was produced using the model, in_CoastFlood (a tool for GIS), developed by the SGSS for the rapid processing of coastal hazard maps, pursuant to Legislative Decree 49/2010. For each of the three scenarios (Tr10, Tr100 and Tr>100) a new 'run' of the model was carried out, using as a high-resolution topographical basis the DTM 2012 (or 2010, in areas without coverage 2012), both DTMs are more accurate than the DTM 2008 used for hazard maps under the Floods Directive in 2013. For the extraction of the hinges the modeling is interrupted when the 'damping surface' is generated, from which the DTM 2012 is subtracted, thus obtaining a 'grid' of quotas, which represents the hinges. The modelling was preceded by a quality test phase that showed that the result, in terms of the extent of floodable areas, did not differ from the areas mapped in 2013. The test also included comparisons with: 1) flood maps and wings obtained with two-dimensional model DHI Mike 2 in two sites on the regional coast (Lido di Savio and Cesenatico); 2) the data measured on the occasion of the 100-year storm event of 6-7 February 2015. The results of the comparisons were very comforting. The classification is represented in altimetric bands (6 classes of water height): minimum class 0-50 cm and maximum > 250 cm.
