Flood events and flood types for a large sample of catchments in Europe

This dataset provides flood events and flood types for the period 1981–2012 for a selection of 863 catchments in Europe, which are part of the Global Runoff Data Centre database (GRDC) and are uninfluenced by large dams. It accompanies an analysis by Brunner and Fischer (2022), which assesses how spatial flood connectedness varies by flood generation process using a flood event classification scheme distinguishing between three rainfall-driven and two snowmelt-influenced flood types.
The flood types were determined using the classification scheme by Fischer et al. 2019, which separates between three rainfall-induced flood types and two snowmelt-influenced types:
R1: flood events with high flood peaks and small volumes, associated with heavy rainfall of high intensity
R2: flood events with moderate peak and volume, associated with medium-duration rainfall of uniform intensity
R3: flood events with large volume, associated with long, successive rainfall events
S1: rain-on-snow floods, where rainfall falls on a snow cover, i.e. associated with high amounts of rainfall but less snow melt compared to snow melt floods
S2: snow melt floods, where the snow cover melts, i.e. associated with a high amount of snow melt but no or only a small amount of rainfall
