A coupled hydro – mechanical approach for modelling the volume change behaviour of compacted bentonite

Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu

The volumetric response of compacted bentonites against environmental actions is a key aspect in most designs of nuclear waste repositories. The safety assessment of such repositories must account for robust and reliable models of stress–strain for bentoni ...

Hydraulic Transport Through Calcite Bearing Faults With Customized Roughness: Effects of Normal and Shear Loading

Marie Estelle Solange Violay, Mateo Alejandro Acosta

Understanding fluid flow in rough fractures is of high importance to large scale geologic processes and to most anthropogenic geo‐energy activities. Here we conducted fluid transport experiments on Carrara marble fractures with a novel customized surface t ...

Hydro-mechanical behaviour of a sandy silt from a river embankment

Alessio Ferrari

The paper presents the results of an experimental campaign aimed at characterizing the hydro mechanical behaviour of a sandy silt from a river embankment Due to continuous river level fluctuations and changing climatic and environmental conditions, flood e ...

Density-dependent solute transport in a layered hyporheic zone

David Andrew Barry, Mohsen Cheraghi, Jing Xu, Qihao Jiang

Hyporheic exchange is affected by bedform geometry, which induces complex flow paths within the bedform. Additional factors that influence flow and solute transport in the hyporheic zone are layered profile sediments and density-driven flow. This study exp ...

Thermal Effects on Flow and Salinity Distributions in Coastal Confined Aquifers

David Andrew Barry, Li Pu, Ho Ling Li

Coastal aquifers provide an important hydrologic connection between terrestrial freshwater and oceanic seawater. Understanding the water flow and salinity distributions in those aquifers is essential to manage seawater intrusion and regional groundwater re ...

Hydro-mechanical response of Opalinus Clay shale: dependency on composition and burial depth

Eleonora Crisci

Shales are sedimentary formation currently studied for their involvement in many geo-energy related applications, such as radioactive waste disposal, CO2 sequestration, oil and gas extraction. In Switzerland the Opalinus Clay shale has been selected has ho ...

Anisotropic behaviour of shallow opalinus clay

Lyesse Laloui, Alessio Ferrari, Alberto Minardi, Eleonora Crisci

Opalinus Clay shale, the selected host geomaterial of a high-level radioactive waste repository in Switzerland, was sourced at shallow depth in a borehole in the northern part of the country. Pairs of specimens, retrieved from the same depth were prepared ...

Impact of Mineralogical Composition on Geotechnical Properties of Opalinus Clay

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

Opalinus Clay is the selected host geomaterial for the construction of underground geological disposals for radioactive waste in Switzerland. The formation has been studied in several sites, i.e. the Mont Terri laboratory, and several boreholes in the nort ...

H2-fuelled microbial metabolism in Opalinus Clay

Rizlan Bernier-Latmani, Luca Loreggian, Carla Perez Mon, Niels Burzan, Aislinn Ann Boylan

In Switzerland, the Opalinus Clay formation is considered the most likely host rock for a deep geological repository for nuclear waste. In deep geological repositories, H2 is expected to be the most abundant gas formed from the degradation of waste and fro ...
