in flooding were evaluated at 67 sites in Finland with var-
iable sizes of runoff areas using a conceptual hydrological model and 20 climate scenarios from both glo-
bal and regional climate models with the delta change approach. Floods with a 100-year return period
were estimated with frequency analysis using the Gumbel distribution. At four study sites depicting dif-
ferent watershed types

season cannot begin before March prevents untimely detection. Once
the maximum is found, the first 10-day period with accumulated melting exceeding 20 mm
and a median temperature above 0°C is identified and the first day of this period selected as
the onset date. In the case of Búðarháls in Figure 6, the filter picked 06/04 correctly as the
beginning of the melt season.
The third filter
