Influence of environmental factors on the structures of bacterial communities in a chloroethene – contaminated aquifer

Christof Holliger, Pierre Rossi, Noam Shani

Numerous industries have been using chloroethenes (CEs), mainly tetrachloroethene and trichloroethene, as non-flammable solvents since the beginning of the 20th century. Massive usage, along with careless handling and storage, made CEs one of the most abun ...

Effect of mineral reactions on the hydraulic properties of unsaturated soils: Model development and application

David Andrew Barry, Laurin Wissmeier

The selective radius shift model was used to relate changes in mineral volume due to precipitation/dissolution reactions to changes in hydraulic properties affecting flow in porous media. The model accounts for (i) precipitation/dissolution taking place on ...

BACTERIAL COMMUNITIES IN A CONTAMINATED AQUIFER: INFLUENCE OF ENVIRONMENTAL VARIABLES

Christof Holliger, Pierre Rossi, Noam Shani

Numerous industries have been using chlorinated ethenes (CEs), mainly tetrachlorethene and trichloroethene, as non-flammable solvents since the beginning of the 20th century. Massive usage, along with careless handling and storage, made CEs one of the most ...

Numerical simulation of wave motion and its interaction with groundwater flow in coastal aquifers

David Andrew Barry, Alessandro Brovelli, Roham Bakhtyar

Groundwater regime has an important role in coastal sediment transport near the coast and beach profile changes. Hitherto, accurate and complete nature of the interaction between wave motions, underground water and beach sediment transport is not yet known ...

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 ...

Integrated Thermo-economic Modeling of Geothermal Resources for Optimal Exploitation Scheme Identification

To be profitable, a geothermal energy system must effectively and economically convert a given resource into useful energy services to be delivered to the consumer during different periods of the year. These services include electricity, district heating, ...

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 ...

Modeling groundwater and benzene discharge to a river from an alluvial aquifer subject to strong interactions with surface water

Jordi Batlle-Aguilar

Modeling groundwater flow and contaminant transport in industrialized and urbanized alluvial plains is challenging because of the dynamic nature of the strongly interacting river – groundwater system and the scarcity of data. An original combined regional ...

Evidence of inception horizons in karst conduit networks

Laurent Tacher, Marco Filipponi, Pierre-Yves Jeannin

This paper outlines the conclusion from an analysis of 18 large cave systems around the world, comprising more than 1500 km of conduits. The 3D geometry of complex cave systems have been analysed in relation to their geological context as well as their hyd ...

Geological heterogeneity in landslides

Boris Matti

Significant progress has been made these last decades in the development of hydrogeological numerical flow modelling for describing the hydrodynamic behaviour of landslides. However, these new sophisticated methods are still very seldom used in the problem ...
