Although the majority of soils are unsaturated, their mechanical behaviour is still not well defined. This dissertation presents first an experimental study of an unsaturated silt and then proposes an elasto-plastic constitutive law to model the behaviour ...
This study investigates the influence of petroleum hydrocarbons on a microbial community in the vadose zone under field conditions. An artificial hydrocarbon mixture consisting of volatile and semi-volatile compounds similar to jet-fuel was emplaced in a p ...
Performance differences in the growing number of electromagnetic (EM) sensing systems designed to predict soil water content from dielectric permittivity estimates suggests the need for a standardized characterization methodology. The objectives of this st ...
We examine the development of instability studies in the oil industry and in soil physics, the former being far more advanced has tended to mold the latter. This had some unfortunate consequences as oil studies tended to rely heavily on Hele-Shaw cells, wh ...
Cut-and-cover tunnels behavior at ultimate limit state depends strongly on the interactions between the foundation soil, the backfill and the reinforced concrete structure. Characterization of the potential failure modes of these types of structure necessi ...

A numerical simulation of the hydro-mechanical behaviour of an unsaturated porous medium is presented. The coupled hydro-mechanical model used is based on the continuum theory of mixtures and treats the unsaturated soil as a three phase porous medium (soli ...
An understanding of the behaviour of saturated/unsaturated soils is important for the design and analysis of geostructures. In this paper a continuum approach based on a structured thermodynamic theory of mixtures developed by Svendsen & Hutter (1995), in ...
The Lund-Potsdam-Jena Dynamic Global Vegetation Model (LPJ) combines process-based, large-scale representations of terrestrial vegetation dynamics and land-atmosphere carbon and water exchanges in a modular framework. Features include feedback through cano ...
