Hydrological regimes

Hydrologic regimes / monthly river flows

Switzerland shows different climate regimes and a high number of hydrological regimes. The hydrologic regimes are described in the hydrological atlas and can also be visualized here: map.geo.admin.ch. ATTENTION: the hydrological regime names are mixed up for the jurassien regimes 11 and 12 (still on 18 Aug 2021), the names are correct, the numbers are inverted; for the correct names, see this Atlas pdf (large file): 11. pluvial jurassien, 12. nivo-pluvial jurassien

Jérôme Dujardin (CRYOS, EPFL) shares his code that uses the above data to estimate monthly river flows and hydrological regimes at any location within Switzerland, see zip file.

Important: the above data sets come with some explanation, partly not in English. At the best of my understanding

Climatic regimes

I am not aware of a good resource on the climatic regimes in Switzerland. The terminology and climate division that is used by the Swiss Institute for Snow and Avalanche Research SLF is explained here,
