This article presents MassMov2D, a two-dimensional model of mud and debris flow dynamics over complex topography, based on a numerical integration of the depth-averaged motion equations using a shallo...
Simulating debris flows through a hexagonal cellular automata model: SCIDDICA S3–hex
debris flows a hexagonal cellular automata model
2009/12/10
Cellular Automata (CA) represent a formal frame for dynamical systems, which evolve on the base of local interactions. Some types of landslide, such as debris flows, match well this requirement. The l...

Debris flows on forested cones–reconstruction and comparison of frequencies in two catchments in Val Ferret,Switzerland
Debris flows forested cones reconstruction comparison frequencies catchments
2009/12/30
Debris flows represent a major threat to infrastructure in many regions of the Alps. Since systematic acquisition of data on debris-flow events in Switzerland only started after the events of 1987, th...
Numerical simulation of debris flows triggered from the Strug rock fall source area,W Slovenia
Numerical simulation debris flows Strug rock fall source area
2009/12/29
The Strug landslide was triggered in December 2001 as a rockslide, followed by a rock fall. In 2002, about 20 debris flows were registered in the Kosec village; they were initiated in the Strug rock f...
