Influence of physical factors and geochemical conditions on groundwater acidification during enhanced reductive dechlorination

David Andrew Barry, Alessandro Brovelli, Clare Robinson

Enhanced reductive dehalogenation is an attractive in-situ treatment technology for chlorinated contaminants. The process includes two acid-forming microbial reactions, that is, fermentation of an organic substrate to hydrogen and short chain fatty acids f ...

Effect of stone coverage on soil erosion

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

Soil surface coverage has a significant impact on water infiltration, runoff and soil erosion yields. In particular, surface stones protect the soils from raindrop detachment, they retard the overland flow therefore decreasing its sediment transport capaci ...

Species-specific effects of polyploidisation and plant traits of Centaurea maculosa and Senecio inaequidens on rhizosphere microorganisms

Alexandre Buttler, Edward Mitchell, Aurélie Thébault

Invasive plant species represent a threat to terrestrial ecosystems, but their effects on the soil biota and the mechanisms involved are not yet well understood. Many invasive species have undergone polyploidisation, leading to the coexistence of various c ...

Ability of One-Dimensional Hairsine-Rose Erosion Model to Predict Sediment Transport over a Soil with Significant Surface Stones

David Andrew Barry, Seifeddine Jomaa

Surface stones affect erosion rates by reducing raindrop-driven detachment and protecting the original soil against overland flow induced-hydraulic stress. The aims of this study were, (i) to quantify how the stone characteristics affect the total sediment ...

On the Diurnal Soil Water Content Dynamics during Evaporation using Dielectric Methods

Marc Parlange, Ivan Lunati, Scott W. Tyler

The water content dynamics in the upper soil surface during evaporation is a key element in land–atmosphere exchanges. Previous experimental studies have suggested that the soil water content increases at the depth of 5 to 15 cm below the soil surface duri ...

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 ...

Using the raindrop size distribution to quantify the soil detachment rate at the laboratory scale

David Andrew Barry, Alexis Berne, Seifeddine Jomaa, Joël Jaffrain

Rainfall simulators are beneficial tools for studying soil erosion processes and sediment transport for different circumstances and scales. They are useful to better understand soil erosion mechanisms and, therefore, to develop and validate process-based e ...

Ability of One-Dimensional Hairsine-Rose Erosion Model to Predict Sediment Transport over a Soil with Significant Surface Stones

David Andrew Barry, Seifeddine Jomaa

Surface stones affect erosion rates by reducing raindrop-driven detachment and protecting the original soil against overland flow induced-hydraulic stress. Numerous studies have shown that the effect of surface stones on erosion depends on both the stone c ...

Soil erosion under multiple time-varying rainfall events

David Andrew Barry, Seifeddine Jomaa

Soil erosion is a function of many factors and process interactions. An erosion event produces changes in surface soil properties such as texture and hydraulic conductivity. These changes in turn alter the erosion response to subsequent events. Laboratory- ...
