Instrumented Field Sites
Large Instrumented Field
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.
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
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
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.
