Mechanical performance and upscaling of bio-improved soils

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 ...

Increasing temperature and vapor pressure deficit lead to hydraulic damages in the absence of soil drought

Pascal Turberg, Charlotte Grossiord, Eugénie Isabelle Mas, Laura Mekarni, Philipp Schuler, Leonie Corine Schönbeck

Temperature (T) and vapor pressure deficit (VPD) are important drivers of plant hydraulic conductivity, growth, mortality, and ecosystem productivity, independently of soil water availability. Our goal was to disentangle the effects of T and VPD on plant h ...

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 ...

Colloid transport and distribution in the hyporheic zone

David Andrew Barry

Colloids moving from the stream into the hyporheic zone may have a negative impact on aquatic ecosystems as they are potential contaminants or carriers of contaminants. Moreover, retained colloids in the hyporheic zone could not only reduce the exchange fl ...

A decade of progress and turning points in the understanding of bio-improved soils: A review

Lyesse Laloui, Dimitrios Terzis

Research and practice in the broader fields of civil and geotechnical engineering had long ignored the presence of living microorganisms in the subsurface and the way it impacts conventional practices. In the last 10 years, the term “microbial induced calc ...

Composition and superposition of alluvial deposits drive macro-biological soil engineering and organic matter dynamics in floodplains

Claire Guenat, Pascal Turberg, Rodolphe Schlaepfer, Renée-Claire Le Bayon, Andreas Cedric Schomburg

Soil structure formation in alluvial soils is a fundamental process in near-natural floodplains. A stable soil structure is essential for many ecosystem services and helps to prevent river bank erosion. Plants and earthworms are successful soil engineering ...

Resilience of riverbed vegetation to uprooting by flow

Paolo Perona, Benoît Crouzy

Riverine ecosystem biodiversity is largely maintained by ecogeomorphic processes including vegetation renewal via uprooting and recovery times to flow disturbances. Plant roots thus heavily contribute to engineering resilience to perturbation of such ecosy ...

Chemical composition, nutrient-balancing and biological treatment of hand washing greywater

Eva Reynaert

On-site biological hand washing water treatment can improve global access to safe hand washing water, but requires a thorough understanding of the chemical composition of the water to be treated, and an effective treatment strategy. This study first presen ...

Effects of drought on the effectiveness of Phalaris arundinacea and Impatiens glandulifera in building up soil aggregates – a microcosm approach

Thomas George McMullin

Near natural floodplain ecosystems are not only stressed by frequent inundations over a year but also by periodical droughts in summer due to their reduced water retention capacity. To maintain floodplain habitats as biodiversity hotspots, a stable soil st ...

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 ...
