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 ...

Global Mapping of Soil Water Characteristics Parameters— Fusing Curated Data with Machine Learning and Environmental Covariates

Sara Bonetti, Dani Or

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 ...

Soil-structure interaction of surface footings

Lyesse Laloui, Cristiano Garbellini

Limit-state analysis of soil-structure interacting systems is a classical problem in theoretical and applied soil mechanics. Usually, the capacities of both components are evaluated separately. However, it is well known that soil-structure interaction play ...

A framework for quantifying hydrologic effects of soil structure across scales

Sara Bonetti, Dani Or

Earth system models use soil information to parameterize hard-to-measure soil hydraulic properties based on pedotransfer functions. However, current parameterizations rely on sample-scale information which often does not account for biologically-promoted s ...

Global Prediction of Soil Saturated Hydraulic Conductivity Using Random Forest in a Covariate‐Based GeoTransfer Function (CoGTF) Framework

Sara Bonetti, Dani Or

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 ...

Predicting spatial patterns of soil bacteria under current and future environmental conditions

Nicolas Jean Philippe Guex, Jan Roelof van der Meer, Marco Pagni, Aline Buri

Soil bacteria are largely missing from future biodiversity assessments hindering comprehensive forecasts of ecosystem changes. Soil bacterial communities are expected to be more strongly driven by pH and less by other edaphic and climatic factors. Thus, al ...

SoilKsatDB: global database of soil saturated hydraulic conductivity measurements for geoscience applications

Sara Bonetti, Dani Or

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 ...

OUR COMMON SOILS: West Lausanne Urbanization as Anthropedogenesis, A Section through the Spaces and Times of Urban Soils

Antoine Vialle

Motivated by ever-increasing soil degradation and artificialization due to past and present urban growth dynamics, the current trend of spatial planning policies at the European and Swiss levels is promoting increased soil protection, by avoiding new devel ...

Advances in the Soil-Structure Interaction Analysis -- from Surface Footings to Thermoactive Deep Foundations

Cristiano Garbellini

Mutual interactions between soil and foundation play a fundamental role in the overall behaviour of constructions. Therefore, it is not surprising that soil-structure interaction has been the subject of numerous research works. This doctoral thesis is a th ...

Stability of tropical forest tree carbon-water relations in a rainfall exclusion treatment through shifts in effective water uptake depth

Charlotte Grossiord

Increasing severity and frequency of drought is predicted for large portions of the terrestrial biosphere, with major impacts already documented in wet tropical forests. Using a 4-year rainfall exclusion experiment in the Daintree Rainforest in northeast A ...
