Mechanical performance and upscaling of bio-improved soils

Ray Harran

Ecological awareness, pressing climate considerations and rising need for soil stabilization push forward the quest for alternative solutions in geotechnical engineering such as Microbially Induced Carbonate Precipitation (MICP). Precipitated crystals serv ...

Effects of large macropores on soil evaporation in salt marshes

David Andrew Barry

The occurrence of macropores in salt marsh sediments is a natural and ubiquitous phenomenon. Although they are widely assumed to affect pore-water flow in salt marshes significantly, the mechanisms involved and their extent are not well understood. We cond ...

Quantitative analysis of the crystalline bond lattice of bio-improved soils using micro-computed tomography

Lyesse Laloui, Dimitrios Terzis

The study presents a comprehensive characterization of the fabric of bio-improved soils by introducing an image based quantitative analysis of the crystalline bond lattice, as a means of better understanding and interpreting the observed mechanical respons ...

Macropores and water flow in soils revisited

The original review of macropores and water flow in soils by Beven and Germann is now 30 years old and has become one of the most highly cited papers in hydrology. This paper attempts to review the progress in observations and theoretical reasoning about p ...

The herbicide glyphosate and its metabolite AMPA in the Lavaux vineyard area, western Switzerland: Proof of widespread export to surface waters. Part II: The role of infiltration and surface runoff

Luiz Felippe De Alencastro

Two parcels of the Lavaux vineyard area, western Switzerland, were studied to assess to which extent the widely used herbicide, glyphosate, and its metabolite aminomethylphosphonic acid (AMPA) were retained in the soil or exported to surface waters. They w ...

Analysis of time compression approximations

David Andrew Barry, Marc Parlange

TCA, time compression approximation, is a practical and often quite accurate tool to predict postponding infiltration for field applications. A modified approximation (MTCA) can be used just as easily and, in general, will reduce the error by about 50%. Th ...

Effects of crab burrows on pore water flows in salt marshes

David Andrew Barry

Macro-pores such as crab burrows are found commonly distributed in salt marsh sediments. Their disturbance on the soil structure is likely to influence both pore water flows and solute transport in salt marshes; however, the effects of crab burrows are not ...

Evolution of unsaturated hydraulic conductivity of aggregated soils due to compressive forces

Dani Or

Prediction of water flow and transport processes in soils susceptible to structural alteration such as compaction of tilled agricultural lands or newly constructed landfills rely on accurate description of changes in soil unsaturated hydraulic conductivity ...

Depuration of highway runoff water into grass-covered embankments

The management of polluted road runoff water is an important issue in environmental protection. A strategy could be to perform local depuration by infiltration into the soils of the embankment, but knowledge for designing such systems is lacking. This stud ...

Assessment of structural evolution of aggregated soil using neutron tomography

Lyesse Laloui, Laurent Vulliet, Azad Koliji

The advanced non-destructive method of neutron tomography, together with image analysis, is used to evaluate the structural evolution of an aggregated soil during one-dimensional compression tests. Aggregation of primary particles is a commonly observed ph ...

Study of hydrological processes by the combination of environmental tracing and hillslope measurements: application on the Haute-Mentue catchment

André Musy

The objective of this research is to improve the comprehension of the hydrological behaviour of natural catchments. The main originality of this work is to associate different types of measurement in order to obtain a better vision of hydrological processe ...
