The rock slope instability "Spitze Stei" constitutes a risk for the touristic infrastructure around lake Öschinensee and the village Kandersteg. Our project task will investigate the mechanisms which led to the slope destabilisation and analyse scenarios for slope failures.
The CCAMM cluster "Cascading Processes"develops knowledge and models that can be used to anticipate future cascading events. At "Spitze Stei", Kandersteg BE, we study the cascading processes: rock slope instability, debris flow, rock/snow avalanches and lake outburst floods.
Our project aims to collaborate with various proposed CAMM II projects within the clusters "Cascading processes' and "Early warning systems", providing meteorological, snow cover, ground temperature and snow melt data at different temporal and spatial scales.
The main objective of this study is to improve high-resolution seasonal snow cover predictions for large river basins in the Alps. Key to these improvements are the coupling of physically based models for both atmospheric and snow cover processes to better resolve processes that act at the snow - atmosphere interface.
The WSL program Climate Change Impacts on Alpine Mass Movements (CCAMM) comprises projects covering a range of topics in natural hazards. Most investigations use models and thus require climate forcing data. The aim of this task is to provide meteorological forcings at the slope scale and in high temporal resolution.
What are the processes determining wintertime snow deposits in Alpine terrain? How does the energy balance of a thinning snowpack shift in springtime conditions? And why do some patches of snow persist longer than others?
