Rockfall experiments help to improve risk assessment
Researchers from the WSL Institute for Snow and Avalanche Research SLF and ETH Zurich have spent four years conducting rockfall experiments, enabling them to compile the most comprehensive set of measurement data to date. Among other things, the results show that wheel-like rocks have a wider lateral spread than cube-shaped rocks. The new findings have important implications for hazard assessment and the dimensioning of protective structures. Based on the measurement data, calculation programs can be calibrated and refined to give a more accurate representation of reality.
