Table A1. Classification of the gauging stations (including their catchment area, mean Q, and mean
catchment elevation) in cluster 1, cluster 2, and cluster 3 (for the yearly scale) using our suggested
Wavelet Transform Coherence (WTC) approach and the k-means approach. Gauging stations whose
classification differs are highlighted in grey.

Table A3. Topological information about the final clusters obtained merging different temporal scales,
including the class, the number of stations belonging to that specific class, the closing station of the class
and its catchment area (i.e., the maximum spatial extension of the cluster), the smallest nested catchment
and its area and if all stations belonging to the cluster are nested or not nested. Clusters with only one
station do not have entries for the smallest nested catchment, the smallest nested area and if all stations
belonging to the cluster are nested or not nested.
