Monitoring shallow geothermal aquifers with active‐source distributed acoustic sensing: A prognostic feasibility study on the University of Leeds Geothermal Campus

Near Surface Geophysics, EarlyView.
Abstract The United Kingdom's shallow aquifers offer significant but underdeveloped geothermal energy resource. Seismic methods can help address this by improving the understanding of aquifer heterogeneity and potentially allowing long‐term monitoring of thermal plumes.

The performance of unsaturated shear strength models of silt soils using the soil water characteristics curve

Results in Engineering
Various studies have investigated soils' unsaturated shear strength properties using the modified triaxial testing machine, which is costly, and time-intensive for standard geotechnical procedures.

Recovery from electrode position uncertainties in geophysical electrical resistance tomography – Application to moisture transport imaging

Near Surface Geophysics, EarlyView.
Abstract In studies of subsurface hydrology, monitoring and imaging techniques are used to estimate the moisture content, or to track moisture or injected tracer movement. One applied imaging technique is electrical resistance tomography (ERT), in which measurements collected using electrodes placed on the ground surface or in boreholes are used to ...

A pore network modeling approach to bridge void ratio‐dependent soil water retention and unsaturated hydraulic conductivity curves

Engineering Reports
In geotechnical engineering, understanding the relationship between soil permeability and deformation is essential, particularly for applications like earth dams, where compaction‐induced permeability reduction is crucial for performance optimization. In

A reconstructed Pangea would result in lower biodiversity

Oikos, EarlyView.
Driven by globalization and climatic change, rates of biological invasion are on the increase. Although these increasing rates are widely expected to lead to increased rates of extinction, it has been argued that these ‘newly arrived' species might increase biodiversity.

Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane

Journal of Polymer Science, EarlyView.
Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...

Revisiting bare‐ground evaporation in a high‐resolution numerical weather prediction system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An improved method is proposed to parameterize evaporation in numerical weather prediction models. The figure shows dew‐point temperature forecast error (standard deviation of forecast error and bias) versus lead time over the North Plains region during spring 2022 for three parameterizations: CTL, the α$$ \alpha $$ method of Jacquemin and Noilhan; IFS:

Expansive clays, collapsing sands, unbound pavement materials and unsaturated soil theory

, 2014
The importance of soil suction on the behaviour of unsaturated geomaterials is widely recognized. Unsaturated soil theory relies heavily on Soil Water Characteristic Curves (SWCC), which can be established experimentally. The primary use of an SWCC is to
