20 Years Debris Flow Testing

18 August 2025

Geobrugg celebrates 20 Years of Research and Experience in Debris Flow Protection. In 2005, a debris flow hit an instrumented barrier in the Illgraben with full force – marking the start of a new era in debris flow protection. Together with the Swiss Federal Institute for Forest, Snow and Landscape Research WSL, this pioneering test became the foundation for

- A load model for debris flows
- UX/VX standard barrier development & certification
- Decades of research, PhD work, and global deployments

Today, Geobrugg barriers protect communities worldwide – proven in hundreds of real events.
