Instrumented Field Sites

Large Instrumented Field Sites

The WSL operates several unique instrumented field sites for mass movements. There researchers can investigate snow avalanches, debris flows, rockfall, and debris avalanches (or hillslope debris flows; Hangmuren in German) at a natural scale. The field sites are equipped with modern sensors, often developed at the WSL-SLF, which allow measurement of parameters such as flow speed, impact pressure, or shear stress, during an artificial release or a spontaneous natural event. These data serve to increase our understanding of natural hazards processes. They also are used directly in various models (e.g. RAMMS), which are intended for use by practitioners and researchers for the analysis and evaluation of natural hazards and the production of hazards maps, as well as to support the development of hazard mitigation concepts.

Small-scale laboratory experiments

Not all natural hazards processes can be investigated in the field with sufficient accuracy. For this reason the WSL-SLF runs various experiments in the laboratory or at the field sites at a small scale

Laboratory debris flow channel
WSL Laboratory

The laboratory at the WSL offers the opportunity to study debris flows at a small scale. With this facility flow, erosion, and impact forces for a variety of different natural and artificial materials can be performed and analyzed with a variety of instrumentation.

MODOEK - Model Ecosystem Facility
MODOEK

Die Modellökosystemanlage (MODOEK) wurde 1992 gebaut und erstmals in Betrieb genommen. Zurzeit steht eine Modernisierung der Steuerung bevor. In der Anlage wurden seit 1992 mehrjährige interdisziplinäre Projekte erfolgreich durchgeführt.

Long-term Forest Ecosystem Research Programme LWF
LWF

Swiss forests are exposed to changing environmental conditions. The consequences of air pollution and climate change on the forest are important questions which the Long-term Forest Ecosystem Research Programme LWF seeks to answer.
