Data collated from field studies and experimentation is providing the essential calibration data to test and validate the new RAMMS rockfall (see Figure below) model which we are developing in collaboration with the Centre of Mechanics, Department of Mechanical & Process Engineering ETH Zurich. The RAMMS:rockfall model employs rigid body mechanics which permits an explicit description of arbitrary three dimensional polyhedral bodies, including natural rock-shapes (see Figure below). Introducing real rock-shapes into rockfall modelling enables a better inclusion of the natural variability of rock-shapes and sizes generated from differing geological settings. With this we come closer to modelling the true nature of rockfall runout behaviour, integrating rock-shape and the release kinematics characteristic of site specific rockfall hazards.



RAMMS Rockfall is currently under development. We estimate that the module will get commercially available in 2014.
