Effect of available entrainable material on a viscous gravity current including run-out characteristics and internal flow properties.

Christophe Ancey, Belinda Margaret Bates

It has long been accepted that entrainment of loose material by geophysical gravity flows such as dense snow avalanches and debris flows may change their behaviour significantly. Run-out distances and bulk-flow velocities are notable examples of susceptibl ...

Triggering mechanisms and geomorphological implications of debris flows in subaquatic canyons: The Rhone delta (Lake Geneva, Switzerland, France)

Nicolas Le Dantec

Subaquatic canyons in deltas are major pathways for the transport of particles from rivers / the upper delta slops to the deep basins. They represent active environments with frequent deltaic failures and massmovements potentially bearing hazard-related (t ...

Sedimentary processes and triggering mechanisms of debris flows in subaquatic canyons in Rhone delta (Lake Geneva, Switzerland, France)

Nicolas Le Dantec

Subaquatic canyons in deltas are major pathways for the transport of particles from land to the deep basins. They represent active environments with frequent deltaic failures and mass-movement deposits potentially leading to hazardous (tsunami waves) and e ...

Floating oil-covered debris from the Deepwater Horizon : Identification and application

Jeremy Samuel Arey

The discovery of oiled and non-oiled honeycomb material in the Gulf of Mexico surface waters and along coastal beaches shortly after the explosion of Deepwater Horizon sparked debate about its origin and the oil covering it. We show that the unknown pieces ...

Ambient seismic noise monitoring of a clay landslide: Toward failure prediction

Michel Jaboyedoff, Clément Michoud

Given that clay-rich landslides may become mobilized, leading to rapid mass movements (earthflows and debris flows), they pose critical problems in risk management worldwide. The most widely proposed mechanism leading to such flow-like movements is the inc ...

Effect of debris on the silicon wafering for solar cells

Christophe Ballif, Adrien Bidiville

The wafers used by the photovoltaic industry are mostly produced by multi-wire slurry sawing. One of the key factors determining the wafer quality (presence of saw marks and chips, increased roughness, wafer thickness variations and wafer strength) is the ...

Effect of climate change on landslide behaviour

Lyesse Laloui, Alessio Ferrari, John Eichenberger

Landslides represent a major threat to human life, constructed facilities and infrastructure in most mountainous regions of the world. Considering future climate scenarios and modified precipitation patterns, the landslide activity will most probably chang ...

Experimental design of a diversion structure of granular debris flows

Fadi Hachem, Michel Studer

Many alpine torrents convey regularly debris flows of high destructive hazard. After several granular events observed in Bruchji?s torrent near the Blatten village in the Swiss Alps, it was decided to manage the risk of similar debris flows by designing an ...

Identification of mechanisms for landslide type initiation of debris flows

Lyesse Laloui, Laurent Vulliet, Georg Klubertanz

The modelling of debris flow initiation in slopes is addressed in this paper. First, possible factors governing debris flow initiation are established. Then, a coupled hydro-mechanical model for deformable porous media with two pore fluids that is used to ...

Impact of small amounts of swelling clays on the physical properties of debris-flow-like granular materials. Implications for the study of alpine debris flow

Paul Bowen, Pascal Boivin, Eric Bardou

The effect of the small fraction of clays on the rheological behaviour of alpine debris flow is poorly understood. This is partly due to the complexity of the debris flow mineralogy and the broad particle size distribution. This study has investigated this ...
