Predictive hydrogeochemical modelling of bauxite residue sand in field conditions

The suitability of residue sand (the coarse fraction remaining from Bayer´s process of bauxite refining) for constructing the surface cover of closed bauxite residue storage areas was investigated. Specifically, its properties as a medium for plant growth ...

Flow measurements in sewer systems based on image analysis: automatic flow velocity algorithm

Luca Rossi, Daniel Sage, Laurent Son Nguyen, Salim Kayal, David Jeanbourquin, David Andrew Barry

Discharges of combined sewer overflows (CSOs) and stormwater are recognized as an important source of environmental contamination. However, the harsh sewer environment and particular hydraulic conditions during rain events reduce the reliability of traditi ...

Modeling the effectiveness of U(VI) biomineralization in dual porosity porous media

David Andrew Barry

Recent attention has focused on the in situ immobilization of uranium by stimulation of dissimilatory metal-reducing bacteria (DMRB). The objective of this work was to investigate the effectiveness of this approach in heterogeneous and structured porous me ...

Sustainable soil and water resources: modelling soil erosion and its impact on the environment

David Andrew Barry

With the projected increase in world population to 9 billion by 2050, along with per capita income growth, the demand for land and water resources is going to increase significantly. Conversion of land to intensive agriculture has led to dramatic decreases ...

Simulation tool for variably saturated flow with comprehensive geochemical reactions in two and three-dimensional domains

David Andrew Barry, Laurin Wissmeier

We present a software tool for simulations of flow and multi-species solute transport in two and three-dimensional domains in combination with comprehensive intra-phase and inter-phase geochemistry. The software uses IPhreeqc, the coupling version of the g ...

Design methodology accounting for the effects of porous medium heterogeneity on hydraulic residence time and biodegradation in horizontal subsurface flow constructed wetlands

Luca Rossi, David Andrew Barry, Alessandro Brovelli, Otoniel Carranza Diaz

Horizontal flow constructed wetlands are engineered systems capable of eliminating a wide range of pollutants from the aquatic environment. Nevertheless, poor hydrodynamic behavior is commonly found resulting in preferential pathways and variations in both ...

Effects of wave forcing on a subterranean estuary

David Andrew Barry, Clare Robinson, Roham Bakhtyar

Wave and tide are important forcing factors that typically co-exist in coastal environments. A numerical study was conducted to investigate individual and combined effects of these forces on flow and mixing processes in a near-shore subterranean estuary. A ...

Land Use Change and Nutrients Simulation for the Siah Darvishan Basin of the Anzali Wetland Region, Iran

David Andrew Barry

The Anzali Ramsar Convention wetland is located in an ecologically and economically important region in Iran. The wetland is largely surrounded by agriculture, natural forests and rangelands (approximately 36% and 63%, respectively). Urban areas consist of ...

Extension of a recent method for obtaining exact solutions of the Bruce and Klute equation

David Andrew Barry

A recent method based on a specific power-law relationship between the matric potential head and the Boltzmann variable was presented by Prevedello et. al. (2008). Here, this relationship was generalized to a range of powers, and the solution extended to i ...

Transport of nonsorbing solutes in a streambed with periodic bedforms

David Andrew Barry

Previous studies of hyporheic zone focused largely on the net mass transfer of solutes between stream and streambed. Solute transport within the bed has attracted less attention. In this study, we combined flume experiments and numerical simulations to exa ...

Exact solutions of the Hairsine-Rose precipitation-driven erosion model for a uniform grain-sized soil

David Andrew Barry, Seifeddine Jomaa

Hairsine and Rose developed a mechanistic, one-dimensional, precipitation-driven erosion model that, since its appearance, has been validated by several sets of experimental results. The model allows any sediment particle to be present in one of three zone ...
