Two-dimensional modelling in 3D alpine terrain - A valuable tool for research and practice

In the field of natural hazards there is a strong need for process models or tools where both the process and interaction with proposed mitigation measures can be evaluated. SLF and WSL have developed a unified software package, for both research and practice, where flow avalanches, debris flows, rockfall, and mitigation measures are combined in one tool. This approach allows exploitation of dynamical similarities in the processes and, because many mitigation measures also protect against hazards for which they were not originally intended, the common interface allows for a comprehensive evaluation of mitigation measures. The user interface (gui) uses many GIS tools, to rapidly define the boundaries of the computational grid and to simplify the definition of the source area for avalanches.

RAMMS consists of the process modules avalanche, debris flow and rockfall (under construction) and a visualization module (gui).
