The development of susceptibility maps for debris flows is of primary importance due to population pressure in hazardous zones. However, hazard assessment by processbased modelling at a regional scale is difficult due to the complex nature of the phenomenon, ...

Unlike fragmental rockfall runout assessments, there are only few robust methods to quantify rock-massfailure susceptibilities at regional scale. A detailed slope angle analysis of recent Digital Elevation Models (DEM) canbe used to detect potential rockfall ...
