Hydrological Study Areas in Switzerland (HUG)

Since 1957, the hydrology division of the FOEN has operated a network of hy-drological study areas aimed at observing long-term changes in the water re-gime within Switzerland’s most natural catchment areas and reflecting the scope of its wide-ranging climatic regions.

Accordingly, it provides the natural runoff depths for around 40 catchment areas and calculates the monthly or annual areal precipitation for many of these areas, as well as the annual evaporation. In addition, it also offers catchment area statistics on morphometry, geology/hydrogeology, pedology and land use are also available.
