February 2015: SLF researchers trigger three avalanches in Vallée de la Sionne (canton of Valais) as part of a large-scale experiment. A pylon equipped with sensors placed in the middle of the test site provides important data for studying the speed, pressure and range of avalanches. In addition to this site, WSL operates other unique test sites where researchers study debris flows, rockfall and sediment transport in streams and rivers under natural conditions. There are also major long-term experiments underway in forests in order to better understand processes in nature and adapt management methods accordingly.
