Using predisposition factors for landslide hazard assessment: a new GIS-based methodology

Switzerland is exceptionally subjected to landslides; indeed, about 10% of its area is considered as unstable. Making this observation, its Department of the Environment (BAFU) introduced in 1997 a method to realize landslide hazard map. It is routinely us ...

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 ...

Hydro-mechanical modelling of a natural slope affected by a multiple slip surface failure mechanism

Lyesse Laloui, Alessio Ferrari

A coupled hydro-mechanical formulation is presented for the analysis of landslide motion during crisis episodes. The mathematical formulation is used to model a natural slope affected by a multiple slip surface failure mechanism, in which pore water pressu ...

Using geotypes for landslide hazard assessment and mapping: a coupled field and GIS-based method

Aurèle Parriaux, Séverine Bilgot

Switzerland is exceptionally subjected to landslides; indeed, about 10% of its area is considered as unstable. Making this observation, its Department of the Environment (BAFU) introduces in 1997 a method to realize landslide hazard maps. It is routinely u ...

After 10’000 years of movements, is the La Frasse landslide stabilized? Numerical modeling of the crises of a large landslide and of its mitigation measures

Lyesse Laloui, Hervé Péron, Jacques Planchat

Using advanced hydro-geological and geo-mechanical finite element simulations, it has been possible to model the behavior of a large slope movement, namely the La Frasse landslide in Switzerland. The slide experiences a permanent movement of about 10 to 15 ...

Differences in experiences in rockfall hazard mapping in Switzerland and Principality of Andorra

Vincent Labiouse, Jacopo Maria Abbruzzese

The need to cope with rockfall hazard and risk led many countries to adopt proper strategies for hazard mapping and risk management, based on their own social and political constraints. The experience of every single country in facing this challenge provid ...

Real-Time avalanche and landslide analysis through sensor networks.

Christophe Ancey

The study of gravity-driven flows (avalanches, landslides, etc.) has made significant progress in the last decade, mainly in the field of numerical models. However, these models rely on a speculative basis and, for lack of field data, modeling the internal ...

Geomechanical modelling of a natural slope affected by a multiple slip surface failure mechanism

Lyesse Laloui, Alessio Ferrari

This paper presents a geomechanical model that was developed to investigate the behaviour of a natural slope located on the bank of the Rhine between the towns of Stein and Mumpf in Switzerland. The slope, affected by a large landslide, constitutes a relev ...

A study of the dynamics of saturated granular assemblages and its implications for transport, stress propagation and failure in marine sediments

Nicolas Le Dantec

The subject of small-scale marine sediment mechanics is an area of active research, motivated by its key role in beach and shelf processes. Much of the existing small-scale work has focused on two-phase flows and particle behavior at the sediment interface ...

Considerations on Swiss methodologies for rock fall hazard mapping based on trajectory modelling

Vincent Labiouse, Jacopo Maria Abbruzzese, Claire Sauthier

Rock fall hazard assessment and hazard mapping are essential for the risk management of vulnerable areas. This paper analyses some issues concerning fragmental rock fall hazard mapping methodologies. Two Swiss approaches based on rock fall trajectory simul ...
