Life 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 ...
2022On the Uncertainty Induced by Pedotransfer Functions in Terrestrial Biosphere Modeling
Hydrological, ecohydrological, and terrestrial biosphere models depend on pedotransfer functions for computing soil hydraulic parameters based on easily measurable variables, such as soil textural and physical properties. Several pedotransfer functions hav ...
2022SoilKsatDB: 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 ...
2021Global Prediction of Soil Saturated Hydraulic Conductivity Using Random Forest in a Covariate‐Based GeoTransfer Function (CoGTF) Framework
Saturated hydraulic conductivity (Ksat) is a key soil hydraulic parameter for representing infiltration and drainage in land surface models. For large scale applications, Ksat is often estimated from pedotransfer functions (PTFs) based on easy-to-measure s ...
2021Geotechnical 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 ...
EPFL2020Effects of large macropores on soil evaporation in salt marshes
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 ...
2020Coupling X-ray computed tomography and freeze-coring for the analysis of fine-grained low-cohesive soils
Claire Guenat, Pascal Turberg, Adrien Francis Olivier Liernur, Renée-Claire Le Bayon, Andreas Cedric Schomburg
This paper presents the coupling of freeze-core sampling with X-ray CT scanning for the analysis of the soil structure of fine-grained, low-cohesive soils. We used a medical scanner to image the 3D soil structure of the frozen soil cores, providing X-ray C ...
Elsevier Science Bv2017Parametric study of soil abrasivity for predicting wear issue in TBM tunneling projects
The lack of reliable methods for evaluation of soil abrasivity and revealing the effects of different parameters on wear rate are nowadays considered as a deficiency in geotechnical investigation during feasibility study, design and construction phases of ...
Pergamon-Elsevier Science Ltd2015Issues involved with thermoactive geotechnical systems: characterization of thermomechanical soil behavior and soil-structure interface behaviour
This paper focuses on the main issues discussed during a session on the impact of thermohydromechanical behavior of soils on thermoactive geotechnical systems, and how they could affect the performance of thermoactive geotechnical systems. Both soil behavi ...
