This is a cross-sectorial quantitative impact study for Climate Change in Switzerland, which extends the qualitative assessment of the OcCC/ProClim “Climate Change and Switzerland 2050”. The aim is to bring together the expertise from different research groups in Switzerland. The new climate data (temperature and precipitation) prepared for the CH2011 (see www.ch2011.ch) shall be used as a common forcing to make the results of different groups and disciplines consistent.

Switzerland is characterised by mountains. Many settlements therefore need protection against landslides and erosion. Plants are often used to stabilise slopes, in addition to wooden and concrete constructions. A new experimental device, developed by SLF technicians, will assist scientists to quantify the stabilising effects of plants.

The signal created by the kinetic impacts of bedload material registered by the geophone over an impact plate is a possible way to quantify bedload transport (The number of impulses per unit time being proportional to the total bedload volume of an event). The project aims to identify the main factors influencing the response of the geophone and to determine which aspects of calibration can be generalized in un-calibrated field sites. Further on, the possibility to extract grain size information from the geophone measurements will be explored

Effekte des Klimawandels wie tauender Permafrost und kollabierende Blockgletscher führen mancherorts zu instabilen Hängen und damit vermehrt zu lockerem Gesteinsmaterial. Betroffen davon ist auch das Mattertal VS. Die WSL erarbeitet dort zusammen mit verschiedenen Partnern Grundlagen für geeignete Schutzmassnahmen.

Droughts and heat waves are expected to become more frequent in Switzerland due to climate change. Droughts have major impacts on water resources, public health, ecosystems and consequently the economy. However, relevant information about relevant economic and societal impacts and knowledge about adequate coping strategies are still lacking.
