Flooding - rough susceptiblitity zones

Definition: The Norwegian Water Resources and Energy Directorate's susceptibility map for flooding is a national map at a general level which shows which areas may be vulnerable to flooding. It will never be possible to make the map entirely accurate, but it is good enough to provide an indication of where the risk of flooding should be assessed in greater detail if new development is in the offing. The information on the map can be used as an initial assessment base in impact assessment and/or risk and vulnerability analyses linked with the municipal plan, and in order to identify potential flood hazard areas. The potential hazard areas can be used as a basis when establishing flood zones requiring special consideration and planning provisions.
