HQStat flood statistics

Data on flood events is managed and statistically evaluated by the FOEN; the findings are made available in the form of result sheets. A systematic statistical evaluation of flood data from the discharge measurement network has been carried out since 1986. For a long time the Hydrology Division applied the "Recommendations on flood risk estimation" issued by the German Association for Water, Wastewater and Waste (DVWK 1979; now DWA). From 2014 it has used a new method set.
