Cartography represents the elements at risk with POLIGONAL geometry that may suffer potential negative consequences arising from floods in relation to the scope of the Unit of Management (UoM) regional basins of Romagna (ITR081), in the portion falling within the Emilia-Romagna Region, expressed in terms of: economic and social activities insistent on the area, plants that could cause accidental pollution in the event of floods, structures and strategic infrastructures (cemeteries, technological systems — ref.
