The first version of SOSlope, a spatially distributed model for the assessment of the disposition of shallow landslides at slope scale is now available and can be downloaded by our members from our tools section (after login). SOSlope differs from many other landslide disposition models because it considers the spatial distribution of root reinforcement and the effect of passive earth pressure as a function of soil deformation. SOSlope is a hydro-mechanical model of slope stability that computes the factor of safety on a hillslope discretized into a two-dimensional array of blocks connected by bonds. Bonds between adjacent blocks represent mechanical forces acting across the blocks due to roots and soil. The scientific article explaining the underlying principles can be found in Cohen and Schwarz (2017; click here).

The ecorisQ association report 2016 was presented at the General Assembly 2017, which was organised on the 15th of november 2017 at the School of Agricultural, Forest and Food Sciences of the Bern University of Applied Sciences in Zollikofen, Switzerland. The number of members and member organisations increased from 190 in 2015 to 217 in 2016. The year report can be downloaded here.

Video of a spectacular rockfall in Switzerland in the community of Evolène (Valais).
As the local geologists said, the rock had been considered as fragile and was under observation. About 2000 cubic meters of rock finally toppled from a cliff, falling down into the valley. A few houses got evacuated and one road closed before although the rocks did not reach this infrastructure.
