Occurrence and dynamics of micropollutants in a karst aquifer

Karst systems represent important yet vulnerable drinking water resources. A wide spectrum of pollutants may be released into karst groundwater from agriculture, livestock farming, private households, and industry. This work provides an overview on the occ ...

Understanding cave genesis along favourable bedding planes. The role of the primary rock permeability

Laurent Tacher, Marco Filipponi, Pierre-Yves Jeannin

Recent studies on the complex 3D geometry of large cave systems around the World allowed us to get statistical evidence of the inception horizon hypothesis. It clearly confirmed the idea that the development of karst conduits under phreatic conditions is s ...

Spatial analysis of karst conduit networks and determination of parameters controlling the speleogenesis along preferential lithostratigraphic horizons

Marco Filipponi

The main objective of this thesis is to improve the understanding of the position and characteristics of karst conduits within a rock massif. Such a characterisation is an important issue in civil engineering and in hydrogeology. Today in practice dissolut ...

Rare earth elements in groundwater from different Alpine aquifers

Aurèle Parriaux, Michaël Bensimon

Rare earth elements (REE) were determined in 39 groundwater samples collected at 14 sites under low- and high-flow conditions. Water samples derived from aquifers hosted in crystalline, molasse, flysch, carbonate and evaporite rocks located in Western Swit ...

Biogeography and spatial variability of bacterial communities associated with chloroethene – contaminated aquifers

Christof Holliger, Pierre Rossi, François Gillet, Noam Shani

Numerous industries and facilities have been using chlorinated ethenes (CEs) as non-flammable solvents since the beginning of the 20th century. These compounds are known to persist in the environment, exerting adverse effects. They have been considered for ...

GEOMECHANICS OF STRUCTURED MATERIALS

Lyesse Laloui

Natural soils and rocks are usually structured at various levels starting from the scale of the particles, pores and their networks up to the field scale. The particular structure in these materials, as often represented by the combination of fabric and bo ...

Constraints on alpine speleogenesis from cave morphology - A case study from the eastern Totes Gebirge (Northern Calcareous Alps, Austria)

Marco Filipponi

The Totes Gebirge is the largest karst massif in the Northern Calcareous Alps (NCA). This paper focuses on the eastern Part, where two major multiphase alpine cave systems (Burgunderschacht Cave System and DOF-Sonnenleiter Cave System) are described with r ...

Effect of competing ions and complexing organic substances on the cadmium uptake by the soil bacterium Sinorhizobium meliloti

Rita Hajdu Schenk

In an effort to improve the understanding and prediction of Cd uptake by soil bacteria, adsorbed and intracellular Cd were determined in unpolluted and highly polluted model soil solutions within a concentration range spanning from 10-9 to 5  10-5 M of ca ...

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 ...
