Instrumented Field Sites

Investigating snow avalanche dynamics at the full-scale test-site: Vallée de la Sionne / Valais

A new Swiss test-site for avalanche experiments has been built to study the overall dynamic behaviour of dense-flow and powder-snow avalanches and to measure avalanche impact forces along their path. The site began operation in 1997/1998 and is a milestone of avalanche dynamics research at the WSL-SLF.

Snow Chute Experiments

Repeatable small scale experiments are an important tool to study the behavior of flowing snow under controlled conditions. Therefore, the SLF operates a large snow chute at the Weissfluhjoch, Davos.
