Flood Directive 2019 II Cycle — Emilia-Romagna Region — Po Basin, risk, linear geometry

Cartography represents the elements at risk with LINEARE geometry that may suffer potential negative consequences deriving from floods in relation to the Union of Management (UoM) district of the Po river (ITN008), in the portion falling within the Emilia-Romagna Region, expressed in terms of networks for the distribution of services, road and motorway networks, railway networks, etc. The risk map developed responds to two different approaches: according to the requirements of Directive 2007/60/EC (Article 6), it indicates the presence and location of the elements exposed within the areas with different flood hazards identified in the hazard maps, distinct in some codified categories; according to the requirements of Legislative Decree 49/2010, combining the probability of flooding with the vulnerability to flood phenomena and with the value of the exposed elements, it classifies the territory into 4 risk classes, R1 (moderate), R2 (medium), R3 (high), R4 (very high), pursuant to D.P.C.M. 29 September 1998.本数据集以线状几何（LINEARE geometry）要素，呈现波河（Po River）ITN008号管理联合体（Union of Management, UoM）辖区内、艾米利亚-罗马涅大区（Emilia-Romagna Region）境内区段的洪涝风险承险对象；此类对象可能因洪涝灾害遭受潜在负面影响，涵盖服务配送管网、公路及高速公路网、铁路网等。本次构建的风险地图遵循两种不同方法：其一，依据《欧盟2007/60/EC指令》第6条的要求，明确标注灾害地图中识别的不同洪涝灾害等级区域内的承险要素的存在与位置，并将其划分为若干标准化类别；其二，依据意大利2010年第49号立法法令的要求，结合洪涝发生概率、洪涝灾害易损性以及承险要素的价值，按照1998年9月29日部长会议法令（D.P.C.M. 29 September 1998）的规定，将研究区划分为4个风险等级：R1（轻度）、R2（中度）、R3（高度）、R4（极高）。
