Rhine basin, coast, risk, linear geometry

The linear geometry cartography, in relation to the type of exposed elements considered, in relation to the scope of the Unit of Management (UoM) of the Rhine Basin Authority (ITI021), represents the risk map of the coastal area and indicates the potential consequences negative deriving from floods expressed in terms of networks (for the distribution of services, road networks, railway networks), etc. The risk map developed responds to two different approaches: based on the requirements of Directive 2007/60/EC (art. 6, paragraph 5), it indicates the presence and location of exposed elements within areas with different hazards identified in the hazard maps, divided into some codified categories (railway, road, distribution networks, etc); based on the requirements of Legislative Decree 49/2010 (art. 6, paragraph 5), by 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 or none), R2 (medium), R3 (high), R4 (very high), pursuant to the D.P.C.M. September 29, 1998.
