Water retention behaviour of shales

Lyesse Laloui, Alessio Ferrari, Valentina Favero

The involvement of shales in engineering fields such as the extraction of shale gas or the nuclear waste geological disposal is mainly driven by the low permeability and the high retention properties of these geomaterials. The high capillary forces develop ...

Shot-clay MX-80 bentonite: an assessment of the hydro-mechanical behaviour

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

This study presents the results of an experimental study conducted to characterise the hydro-mechanical behaviour of shot-clay MX-80 bentonite. In the shot-clay process, granular bentonite was mixed continuously with water and shot on the walls of a tunnel ...

A three-scale cracking criterion for drying soils

Lyesse Laloui

Cracking is a most unwanted development in soil structures undergoing periodic drying and wetting. Desiccation cracks arise in an apparent absence of external forces. Hence, either an internal, self-equilibrated stress pattern resulting from kinematic inco ...

Similarity Analysis between near surface soil moisture and streamflow during recession events in an alpine catchment

Andrea Rinaldo, Marc Parlange, Steven Vincent Weijs, Raphaël Mutzner

Spatial and temporal variability of near surface soil moisture is important for understanding streamflow generation in high altitude mountain catchments since antecedent soil moisture plays an important role in the timing of runoff. For relatively small to ...

A comparison between remotely-sensed and modelled surface soil moisture (and frozen status) at high latitudes

Isabelle Amandine Gouttevin

In this study, the combined surface status and surface soil moisture products retrieved by the ASCAT sensor within the ESA-DUE Permafrost project are compared to the hydrological outputs of the land surface model ORCHIDEE over Northern Eurasia. The objecti ...

Macropores and water flow in soils revisited

The original review of macropores and water flow in soils by Beven and Germann is now 30 years old and has become one of the most highly cited papers in hydrology. This paper attempts to review the progress in observations and theoretical reasoning about p ...

Depletion of Stem Water of Sclerocarya birrea Agroforestry Tree Precedes Start of Rainy Season in West African Sudanian Zone

Marc Parlange, Natalie Claire Ceperley, Theophile Mande

Understanding water use by agroforestry trees in dry-land ecosystems is essential for improving water management. Agroforestry trees are valued and promoted for many of their ecologic and economic beneﬁts but are often criticized as competing for valuable ...

Moisture and energy dynamics in fields soils

Francesco Ciocca

Soil moisture is crucial to water-cycle as it affects infiltration, runoff and land-atmosphere interactions. In dry soils the role of water vapor fluxes becomes essential and causes a tight coupling between soil moisture dynamics and heat transfer, which m ...

Characterization of THM Behaviour of Compacted MX-80 Granular Bentonite Using an Advanced Double-wall Triaxial Cell

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

This paper aims at characterization of thermo-hydro-mechanical behaviour of MX-80 granular bentonite obtained from an innovative double-cell triaxial system. The system has been mainly developed to perform suction controlled tests on unsaturated geomateria ...

Estimation of Soil Moisture from Airborne Hyperspectral Imagery with Support Vector Regression

Jean-Philippe Thiran, Devis Tuia, Frank Grégoire Jean de Morsier, Maurice Borgeaud, Jelena Stamenkovic

In this paper, we propose to estimate soil moisture in bare soils directly from hyperspectral imagery using support vector regression (nu-SVR). nu-SVR is a supervised non-parametric learning technique, e.g. making no assumption on the underlying data distr ...
