Water

Starting with the origin of Switzerland’s abundant water resources, the high amount of precipitation in the Alps, relevant hydrological, water management, social and environmental aspects of water are considered.

Since a large part of Switzerland’s precipitation falls as snow, the storage of water in snow and glaciers plays an important role in the seasonal distribution of runoff, especially in high-altitude catchments. Hydropower, fisheries and recreation depend on reliable runoff. Water therefore has environmental, cultural and economic functions that may at times conflict with one another.

Evolution of the volume of water stored in Swiss glaciers (Rhone and Rhine river basins, Engadine and Ticino). Since the end of the Little Ice Age around 1850, the glacier volume has decreased by half. More than 70% of the remaining volume should be gone by the end of this century. FOEN, 2012.

Wasser in der Schweiz

Wasser ist in der Schweiz selten knapp und meistens gesundheitlich
unbedenklich. Durch neue Konsummuster,
die Klimaänderung und energiepolitische Entscheidungen
verändern sich sowohl die Verfügbarkeit wie die Nutzung
des Wassers.

Effects of climate change on water resources and watercourses

Under the project “Climate Change and Hydrology in Switzerland” (CCHydro) run by the FOEN, the effects of climate change on the water balance in Switzerland by the year 2100 were studied.
