RAMMS 1.8.0 (Rapid Mass Movement Simulation) 
 
RAMMS (Rapid Mass Movement Simulation) is a state-of-the-art numerical simulation model to calculate the motion of geophysical mass movements (snow avalanches, debris flows, rockfall and shallow landslides) from initiation to runout in three-dimensional terrain. 
It was designed to be used in practice by hazard engineers who need solutions to real, everyday problems. It is coupled with a user-friendly visualization tool that allows users to easily access, display and analyze simulation results. 
New constitutive models have been developed and implemented in RAMMS, thanks to calibration and verification at full scale tests at sites such as Vallée de la Sionne (snow avalanches), Illgraben (debris flows), Veltheim (hillslope) and St. Leonard / Walenstadt (rockfall). These models allow the application of RAMMS to solve both large, extreme avalanche, debris flow or block fall events as well as smaller mass movements such as hillslope debris flows, shallow landslides and rock fall. 
 
RAMMS is developed at the WSL Institute for Snow and Avalanche Research SLF in Davos by Marc Christen, Perry Bartelt and others.
