Floods in the Alpine areas of Europe

Abstract : Within the European AdaptAlp initiative (, a specific focus was the detection of trends on river flow regimes in the Alps. The AdaptAlp dataset comprises 177 long series of daily runoff collected over the Alpine region (Austria, France, Germany, Italy, Slovenia and Switzerland). These series cover at least 40 years of daily record, are related to undisturbed catchments and have been thoroughly quality-checked by the partners of the project. A trend analysis was carried out on snowmelt flow indices occurring in spring and summer. Statistical analysis was applied at a local level, testing each site independently and checking its field significance, and secondly with a regional procedure was applied to test if all the stations belonging to the same homogeneous region behave in the same way. The main significant trends can be summarized as follows: 1/ higher spring snowmelt-related flows; 2/ an increase in the volume and peak of snowmelt flows for glacier regimes; 3/ an increase in the duration of the snowmelt season for snowmelt regimes, along with an earlier start to the beginning of the snowmelt season.
