Migration of volatile organic contaminations (VOCs) through a deforming clay liner

David Andrew Barry

A fully coupled thermal–hydraulic–mechanical–chemical (THMC) model was proposed to describe the migration of volatile organic contaminations (VOCs) in unsaturated landfill liners. The vertical soil stress, capillary pressure, air pressure, temperature incr ...

Infiltration in soils with a saturated surface

Marc Parlange, David Andrew Barry

An earlier infiltration equation relied on curve fitting of infiltration data for the determination of one of the parameters, which limits its usefulness in practice. This handicap is removed here, and the parameter is now evaluated by linking it directly ...

A computational platform for integrated modelling of micropollution in the urban environment

Luca Rossi, David Andrew Barry, Timothée Noé Pouchon, Sylvain Coutu

Anthropogenic chemical contaminants are found routinely in our water resources. Although most of these compounds are usually present at low concentrations, they are of concern due to their ecotoxicity, antibacterial resistance and potential harm to human h ...

Treatment of micropollutants in municipal wastewater: Ozone or powdered activated carbon?

Luca Rossi, Luiz Felippe De Alencastro, Jonas Margot, Anoys Magnet, David Andrew Barry

Many organic micropollutants present in wastewater, such as pharmaceuticals and pesticides, are poorly removed in conventional wastewater treatment plants (WWTPs). To reduce the release of these substances into the aquatic environment, advanced wastewater ...

Solute and sediment transport at laboratory and field scale: Contributions of J.-Y. Parlange

David Andrew Barry, Seifeddine Jomaa

We explore selected aspects of J.-Y. Parlange’s contributions to hydrological transport of solutes and sediments, including both the laboratory and field scales. At the laboratory scale, he provided numerous approximations for solute transport accounting f ...

Bacterial versus fungal laccase: potential for micropollutant degradation

Christof Holliger, Julien Maillard, Jonas Margot, David Andrew Barry

Relatively high concentrations of micropollutants in municipal wastewater treatment plant (WWTP) effluents underscore the necessity to develop additional treatment steps prior to discharge of treated wastewater. Microorganisms that produce unspecific oxida ...

Two-phase flow modeling of the influence of wave shapes and bed slope on nearshore hydrodynamics

David Andrew Barry, Roham Bakhtyar, Amir Mehdi Razmi

An Eulerian two-phase flow model (air-water) was used to simulate nearshore hydrodynamic processes driven by wave motion. The flow field was computed with the Reynolds-Averaged Navier-Stokes equations in conjunction with the Volume-Of-Fluid method and the ...

Temporal variability of antibiotics fluxes in wastewater and contribution from hospitals

Luca Rossi, David Andrew Barry, Sylvain Coutu

Significant quantities of antibiotics are used in all parts of the globe to treat diseases with bacterial origins. After ingestion, antibiotics are excreted by the patient and transmitted in due course to the aquatic environment. This study examined tempor ...

Micropollutant dynamics in Vidy Bay - A coupled hydrodynamic-photolysis model to assess the spatial extent of ecotoxicological risk

Florence Bonvin, David Andrew Barry, Tamar Kohn, Amir Mehdi Razmi

The direct discharge of effluent wastewater into Vidy Bay (Lake Geneva) results in the formation of an effluent plume with locally high concentrations of wastewater-derived micropollutants. The micropollutant hotspots above the wastewater outfall present a ...

Modelling city-scale facade leaching of biocide by rainfall

Luca Rossi, Chiara Rota, David Andrew Barry, Sylvain Coutu

A methodology is presented for estimating, at the city scale, the amount of biocide released from facades during rain events. The methodology consists of two elements. First, leaching of a single facade is simulated using a two-region model, one region for ...

Methodology to account for uncertainties and tradeoffs in pharmaceutical environmental hazard assessment

Luca Rossi, David Andrew Barry, Sylvain Coutu

Many pharmaceutical products find their way into receiving waters, giving rise to concerns regarding their environmental impact. A procedure was proposed that enables ranking of the hazard to aquatic species and human health due to such products. In the pr ...

Analysis of acidity production during enhanced reductive dechlorination using a simplified reactive transport model

David Andrew Barry, Alessandro Brovelli, Clare Robinson

Build-up of fermentation products and hydrochloric acid at a contaminated site undergoing enhanced reductive dechlorination can result in groundwater acidification. Sub-optimal pH conditions can inhibit microbial activity and lead to reduced dechlorination ...

Numerical experiments on interactions between wave motion and variable-density coastal aquifers

David Andrew Barry, Alessandro Brovelli, Roham Bakhtyar

A comprehensive two-dimensional (cross-shore) process-based numerical model of nearshore hydrodynamics (based on the Navier-Stokes equations, k-ε turbulence closure and the Volume-Of-Fluid method), beach morphology, and variable-density groundwater flow (S ...

Solute transport in partially-saturated deformable porous media: Application to a landfill clay liner

David Andrew Barry

Based on the one-dimensional Biot consolidation equations, this paper developed an advection-diffusion equation that incorporates saturation, compressibility of the pore fluid and longitudinal dispersivity of the solute transport in an unsaturated, deformi ...

Rain splash soil erosion estimation in the presence of rock fragments

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

Rain splash soil erosion in the presence of rock fragments and different initial conditions was tested in laboratory flume experiments under controlled conditions. The aim of the experiments was to ascertain whether cumulative soil erosion is proportional ...

Numerical experiments on breaking waves on contrasting beaches using a two-phase flow approach

David Andrew Barry, Roham Bakhtyar

A mechanistic understanding of beach environments needs to account for interactions of oceanic forcing and beach materials, in particular the role of waves on the evolution of the beach profile. A fully coupled two-phase flow model was used to simulate nea ...

Analysis of carbon and nitrogen dynamics in riparian soils: Model development

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar

The quality of riparian soils and their ability to buffer contaminant releases to aquifers and streams are connected intimately to moisture content and nutrient dynamics, in particular of carbon (C) and nitrogen (N). A multi-compartment model – named the R ...
