RAMMS - Your Rapid Mass Movement Solution

RAMMS is a physics-based modeling framework for simulating avalanches, debris flows, and rockfall. Used worldwide by engineers, researchers, and risk managers, RAMMS provides scientifically robust tools to analyze natural hazards, design mitigation measures, and support risk-informed decision making.

What’s New

Major Update: RAMMS::Avalanche & RAMMS::DebrisFlow
A major new release is now available, featuring a redesigned GUI, optional NVIDIA GPU acceleration, improved file handling, and several new analysis and workflow tools. RAMMS::Avalanche also introduces PRA Release Tendency mapping, while RAMMS::DebrisFlow includes improved discharge calculations for line profiles (see all new features).

RAMMS::Rockfall
The latest Rockfall release features a redesigned GUI, improved visualization, and powerful new terrain and obstacle impact analyses with automatic CSV and HTML reports. The new Reduced Mode enables efficient large-scale simulations with tens or even hundreds of thousands of trajectories.

RAMMS::RockIce (Beta):
Designed for high-alpine events, this new module simulates rock-ice-avalanche mixtures and cascading processes, including ice melt, water release and the initiation of secondary debris flows. The recent 2026 Nepal rock–ice avalanche and subsequent debris-flow/flood cascade highlights the importance of better understanding such complex high-mountain process chains.
