For the month of August, the highest concentration of stations that exceeded their lowest threshold level was located in Po river basin, Italy, and in Czech Republic, Rhine river basin. A more dispersed distribution of stations with exceedances occurred in Danube river basin (Serbia, Hungary and Slovakia) and in Norway.

Stations that registered discharge values above the 90% were very few. They are located in disperse way in the following countries: Germany, Austria, Norway, United Kingdom and Ireland. In Spain there are some stations with values above 90% due to floods of low duration.

Stations under the 10% quantile were concentrated in central Europe (Germany and Poland), especially in the basins of the Elbe and Oder rivers. Also a few stations are in the Rhine and Vistula river basins (Germany and Poland respectively) and in Belgium and Austria were below the threshold. Furhter, a few stations with low values were found in Norway, Sweden, Romania, Serbia, United Kingdom, Ireland and northern Spain.
