India is regularly associated with heat, spicy food, masses of people – and avalanches? Although not a phenomenon that immediately springs to mind, Indian avalanches are part and parcel of everyday life at the moment for SLF employee Yves Bühler. At the beginning of April 2012 he left Switzerland with his family to work for three months at the Snow and Avalanche Study Establishment (SASE) in Manali.

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.

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 cornices up to several meters high impressively show how strong the wind influences the snow cover in mountains. SLF investigates where the wind erodes and deposits snow and how the snow changes during transport through experiments in a wind tunnel and at the Weissfluhjoch Versuchsfeld.

White Risk is the SLF app for all those who engage in winter activities in the mountains outside marked and open pistes. It gives access to the interactive avalanche bulletin in German, French, Italian and English, as well as the latest snow and weather data for Switzerland. White Risk also provides useful background knowledge to assist in assessing the avalanche danger.

Within the framework of an international research project, the SLF and its German and Austrian partners are using a radar system to conduct a non-destructive investigation of the snowpack from underneath. The goal is to observe the individual layers of the snowpack and their properties and change over time.
