Preliminary Slope Mass Movement Susceptibility Mapping Using DEM and LiDAR DEM

摘要: Hazard mapping in mountainous areas at the regional scale has greatly changed since 1990s thanks to improved digital elevation models (DEM). It is now possible model slope mass movement and floods with a high level of detail order improve geomorphologic mapping. We present examples multi-hazard susceptibility through two Swiss case studies, including landslides, rockfall, debris flows, snow avalanches floods, addition several original methods software tools. The aim these recent developments take advantage availability resolution DEM (HRDEM) for better modeling. Our results indicate good correspondence between inventories hazardous zones based on historical events predictions. This paper demonstrates that by adapting tools issued from modern technologies, it obtain reliable documents land planning purposes over large areas.
