Effect of heterogeneity on enhanced reductive dechlorination: Analysis of remediation efficiency and groundwater acidification

David Andrew Barry, Christof Holliger, Alessandro Brovelli, Clare Robinson, Elsa Marina Lacroix

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

Effect of stone cover on rainfall-driven soil erosion with negligible surface roughness

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

Numerous studies have shown that, for soils with sparse vegetation cover, stones/rock fragments are an important factor controlling the hydrological response and soil erosion yields. Additionally, it has been observed that this effect is complex and ambiva ...

A multi-scale multi-physics model of soil drying

Lyesse Laloui, Hervé Péron

Drying shrinkage is modeled at a microscale as a two-stage process of deformation and evacuation of a two-tube vessel system, based on porosimetry evolution. In the first stage water flow is driven by an external evaporation flux. Flow is associated with a ...

Soil-vegetation patterns in secondary slash and burn successions in Central Menabe, Madagascar

Alexandre Buttler, Jean-Michel Gobat

Slash and burn agriculture is a traditional and predominant land use practice in Madagascar and its relevance in the context of forest preservation is significant. At the end of a cycle of culture, the fields become mostly weed covered and the soil fertili ...

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 ...

Significance of sacred sites for riparian forest conservation in Central Benin

Natalie Claire Ceperley

Ibu odo, or sacred pools or points in the river, are generally respected by Tchabe communities along the Oueme and Okpara Rivers of Central Benin (West Africa). Ibu odo are governed by rules that may influence conservation practices, including bans on fish ...

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 ...

Carbon, oxygen and nitrogen dynamics in a soil profile: Model development and application

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar

In order to meet demands for crops, pasture and firewood, the rate of land use change from forested to agricultural uses steadily increased over several decades, resulting in an increased release of nutrients towards groundwater and surface water bodies. I ...

Dissipation of boundary-induced flow disturbances in cylindrical soil columns

David Andrew Barry

Laboratory soil column experiments, often involving steady flow, have a long and enduring history in hydrology and soil science. Typically, analyses of laboratory column data assume that the flow is both steady and uniform within the soil column. However, ...

Behavior of Unsaturated Aggregated Soil in Oedometric Condition

Lyesse Laloui, Laurent Vulliet, Azad Koliji

Natural and agricultural soils usually possess an aggregated structure; in the sense that they are composed of aggregates and large inter-aggregate pores. Under the natural condition, these soils are usually unsaturated and the large pores are easily drain ...
