Investigation of microbial community dynamics in soil during variable hydrological forcing
Climate change is expected to alter the temporal distribution of precipitation events, leading to prolonged drought periods and an increased frequency of extreme precipitation events. Changes in precipitation pattern will directly affect soil moisture dyna ...
EPFL2024Spatially Explicit Linkages Between Redox Potential Cycles and Soil Moisture Fluctuations
Andrea Rinaldo, Rizlan Bernier-Latmani, Paolo Benettin, Manon Frutschi, Simiao Wang, Filippo Miele, Mitra Asadollahi
Reduction-oxidation cycles measured through soil redox potential (Eh) are associated with dynamic soil microbial activity. Understanding changes in the composition of, and resource use by, soil microbial communities requires Eh predictability under shiftin ...
2023Life cycle environmental assessment of retaining walls in unsaturated soils
Alessio Ferrari, Gianluca Speranza
Retaining structures above groundwater level support soils that are usually in a state of partial saturation and subject to the actions of atmospheric agents. The current design approach considers the possible extremes of soil conditions - either totally d ...
ELSEVIER2022Global Mapping of Soil Water Characteristics Parameters— Fusing Curated Data with Machine Learning and Environmental Covariates
Hydrological and climatic modeling of near-surface water and energy fluxes is critically dependent on the availability of soil hydraulic parameters. Key among these parameters is the soil water characteristic curve (SWCC), a function relating soil water co ...
2022The influence of the crowding assumptions in biofilm simulations
Vassily Hatzimanikatis, Liliana Angeles Martinez
Author summary In nature, many organisms grow in crowded biofilms that protect against stressful conditions, making their control/eradication a challenge. Modeling these microbial systems is a valuable tool for studying the interactions among cells and exp ...
PUBLIC LIBRARY SCIENCE2021On the mechanical behavior of expansive porous media with consideration on chemical effects
Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo
Experimental geomechanics highlights that the mechanical behavior of expansive porous media is variable depending on the pore water chemical composition. These porous media are typically characterized by clay particles, whose activity (Skempton, 1953) (and ...
2021SoilKsatDB: global database of soil saturated hydraulic conductivity measurements for geoscience applications
The saturated soil hydraulic conductivity (Ksat) is a key parameter in many hydrological and climate models. Ksat values are primarily determined from basic soil properties and may vary over several orders of magnitude. Despite the availability of Ksat dat ...
2021Spatio-temporal modeling of the crowding conditions and metabolic variability in microbial communities
Vassily Hatzimanikatis, Liliana Angeles Martinez
The metabolic capabilities of the species and the local environment shape the microbial interactions in a community either through the exchange of metabolic products or the competition for the resources. Cells are often arranged in close proximity to each ...
PUBLIC LIBRARY SCIENCE2021Carbon turnover and microbial activity in an artificial soil under imposed cyclic drainage and imbibition
Water table fluctuations generate temporally and spatially dynamic physicochemical conditions that drive biogeochemical hot spots and hot moments in the vadose zone. However, their role in the cycling of soil C remains poorly known. Here, we present result ...
WILEY2020Geotechnical and environmental performance of retaining structures in unsaturated soils
Presently, environmental issues are considered as critical aspects concerning the market competitiveness in the building and construction sector. However, the construction sector is regarded as one of the main areas contributing to CO2 emissions and resour ...
