Sediment loading predicting post-wildfire debris flows
2020/2/20
The mudslides that follow wildfires in Southern California can be deadly -- and difficult to predict. New National Science Foundation-funded research will help officials identify areas prone to these ...
Geophysical surveying of slopes affected by debris flows: the case of S. Felicea Cancello (Caserta, Southern Italy)
debris flow geophysical surveys S. Felice a Cancello
2015/9/17
This paper contains the results of a series of geophysical investigations carried out on the largest debris flow to
have taken place in Tavernole, S. Felice a Cancello (Caserta, Southern Italy). The ...
Turbidity currents and debris flows represent the most prominent processes of sediment transport from the shallow shelf waters into the deep ocean. These gravity driven flows are capable of transporti...

Debris flows generally propagate along steep mountain torrents with dynamics primarily governed by gravitational and frictional forces. Thus, debris flows modelling can be successfully performed throu...
Description and analysis of the debris flows occurred during 2008 in the Eastern Pyrenees
Description analysis the debris flows occurred the Eastern Pyrenees
2010/10/21
Rainfall-triggered landslides taking place in the Spanish Eastern Pyrenees have usually been analysed on a regional scale. Most research focussed either on terrain susceptibility or on the characteris...
Terraces cover large areas along the flanks of many alpine and prealpine valleys. Soil slips and soil slips-debris flows are recurrent phenomena along terraced slopes. These landslides cause damages t...

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...
