Landslides and flooding in the Alps
- Details
Due to the combination of excessive snowfall, subsequent snowmelt and intense, continuous rainfall (> 160 mm in 48 hrs), many regions in the French and Swiss Alps were affected by shallow landslides, debris flows and flooding between the 30th of December 2017 and the 5th of January 2018. In France, 2 persons were killed in their homes due to the natural hazards and multiple roads were closed (see examples from Switzerland here).
Release of SOSlope (the shallow landslide disposition model)
- Details
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).
3e Journée de Rencontre sur les Dangers Naturels
- Details
The 15th of February 2018, the University of Lausanne organises the third "Journée de Rencontre sur les Dangers Naturels". Here, practitioners and scientists will meet to discuss the question how to make the move from hazard management towards integrated risk management. The meeting takes place in Lausanne (Switzerland) and will mainly be held in French.
