Avalanche catching dams
Information on the expected volume and flow velocity of the avalanche are used to estimate the necessary dam height by a rule of thumb. However these estimation requires expert knowledge to judge the influence of factors such as terrain structure, expected flow characteristics of the avalanche and dam geometry in a proper way.
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.
AVAL-1D: An Avalanche Dynamics Program for the Practice
Avalanche hazard maps are prepared by engineers and land-planners. These experts rely both on practical experience and calculation models. The danger of powder snow avalanches has mostly been ignored, because no suitable model existed before. The goal of this project is to provide snow avalanche professionals with a simple, stable and well-calibrated simulation tool.
RAMMS rapid mass movements
In the field of natural hazards there is a strong need for process models. Researchers of WSL develop a unified software package, for both research and practice, where different kinds of processes are combined in one tool. The package consists of the process modules debris flow, rockfall, snowcover and avalanche, a protect module and a visualization module.
A new Swiss test-site for avalanche Experiments in the 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. |
