DEM Digital Elevation Model, required input data for RAMMS.
Friction parameters The friction parameters used in RAMMS are called μ (Mu) and ξ (Xi), also refered to as MuXi. Via these two parameters, friction differences according to topography and forest are taken into account.
Hydrograph Temporal input mass flux for debris flow modeling
Imagery Georeferenced aerial or satellite remote sensing data used for visualization in RAMMS. They have to be in .tif format and have to come with a world file (.tfw).
Log file Test file containing important information about the calculation.
μ (Mu) dry-Coulomb friction coefficient (-) of the Voellmy model.
RAMMS Rapid Mass MovementS, numerical simulation software for snow-avalanche and debris flow calculations.
Release area Area from where the process releases, defined by polygons and release height.
Release height Defines the mean height of the release area. Together with the release area it defines the release volume.
Release volume Release height multiplied by the release area, displayed in m3.
Runout distance

The point of farthest reach.  Often difficult to define in three-dimensional terrain.

SLF WSL Institute for Snow and Avalanche Research SLF.
Starving The process by which small avalanches stop.  Mass is withdrawn from the front of the avalanche and runs out.
World file A world file is a plain text computer data file used by geographic information systems  to georeference  imagery.
WSL Swiss Federal Institute for Forest, Snow and Landscape Research.
ξ (Xi)
Velocity squared drag coefficient (m/s2) of the Voellmy model.
