Danger Zone Plans of the Federal Water Engineering Administration (BWV) in the Atlasdienst \Wasserbuch\ Vorarlberg

Hazard zone plans are expert assessments of the nature and extent of hazards caused by flood events with the probability of occurrence of a 30-year (HQ30) and 100-yearly (HQ100) measurement flood depiction. In addition, the remaining risk if the measurement event is exceeded (HQ300) examine and assess. Annuality is that period in years in which the overrun of the lying design event has to be calculated once. The result of the planning is the delimitation of different hazard zones (HQ30: Outflow zones; HQ100: Red zones, yellow zones; HQ300: Outflow zones, residual risk areas) and zones for flood discharge or flood protection measures are of particular importance (HQ100: Red-yellow zones, blue zones). Only completed hazard zone plans are presented! Work is ongoing on the development of further hazard zone plans in the competence area of the BWV. If no hazard zones are identified in an area, this does not mean that there is no possible There is danger from floods! There may be danger zone plans in For the time being, elaboration or only drain tests are available. In addition, hazards caused by Sloping water and backlog from canals are not shown, as they do not correspond to the usual annualities Assign (HQ30, HQ100, HQ300) to the underlying drain tests. In these cases, it is recommended to contact the affected municipality or the Abbot. Contact us to find out if there is information about flood hazards.
