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).
