The catchment attributes and performance for a particular regionalisation method are available for each catchment and include area, mean
catchment elevation, mean annual precipitation (P A ), mean annual potential evaporation (E PA ) and mean annual air temperature (T A ).
Groups of regionalisation methods: regression methods (R), spatial proximity methods (SP), geostatistical methods (G) and process-
based methods (PB).
