USGS Training course: Shallow landslide modelling for vegetated slopes using SOSlope

Please join this free training course on SOSlope by USGS on Saturday December 7th.

Description of SOSlope:

  • A new model for slope stability taking into account root reinforcement due to vegetation and tensional/compressional forces arising from both roots and soil
  • Uses displacement-controlled, fibre-bundle model concepts for estimating forces in roots and soil
  • Based on a discrete element formulation
  • Uses a simplified rainfall infiltration model with dual-porosity soil
  • Estimates factor of safety and zones of failure during a rainfall event
  • GUI based, easy to use, accessible via ecorisQ, an international association for natural hazard risk management
