| This study addresses the question of the existence of a parent flood frequency distribution on a European scale.
A new database of L-moment ratios of flood annual maximum series (AMS) from 4105 catchments
was compiled by joining 13 national data sets. Simple exploration of the database presents the generalized extreme value
(GEV) distribution as a potential pan-European flood frequency distribution, being the three-parameter statistical model
that with the closest resemblance to the estimated average of the sample L-moment ratios. Additional Monte Carlo simulations show that the
variability in terms of sample skewness and kurtosis present in the data is larger than in a hypothetical scenario where all the
samples were drawn from a GEV model. Overall, the generalized extreme value distribution fails to represent the kurtosis
dispersion, especially for the longer sample lengths and medium to high skewness values, and therefore may be rejected in a statistical
hypothesis testing framework as a single pan-European parent distribution for annual flood maxima. The results presented in
this paper suggest that one single statistical model may not be able to fit the entire variety
of flood processes present at a European scale, and presents an opportunity to further investigate the catchment and climatic factors
controlling European flood regimes and their effects on the underlying flood frequency distributions. |
