Rockyfor3D allows to simulate the rockfall on roads and comparison of the risk in a situation with and without protective measures such as nets and forest. This provides all the infomation needed to conduct cost-benefit studies of protective measures. How to quantify the risk is explained in a documentation of the Swiss Federal roads office (available in German, French, Italian and English). Different case studies in Switzerland, France and Austria show that a protection forest along main roads easily add up to 1000 $ per year per ha.

 

Here is a relatively stable film showing rebound heights and distances, as well as the stochastic nature, of falling rocks in the Grand Couloir on the Mont Blanc. It shows very well that on steep bedrock/talus slopes, rebounds can be impressivily high and long (> 40 m height).

The version 5.1 of Rockyfor3D is made available today. This new version additionally provides the median, 90th, 95th, 98th and 99th percentile of the simulated energies and passing heights for each cell as raster output. It also saves a NetCDF file called Energy_hist.nc, which can be loaded directly in TrajectoVal3D. This program is developed by Crealp and analyses the frequencies of simulated energies for each cell to automatically propose hazard classes. The methodology is based on Cadanav, which has been developed by Jabeyodoff and Labiouse (2004).
