Hydro‐Mechanical Modelling of Gas Migration in Bentonite: Formulation and Laboratory‐Scale Validation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Gas generation and migration in bentonite buffer materials are critical processes affecting the performance of deep geological repositories for radioactive waste. This study presents a new hydro‐mechanical formulation for simulating gas migration in saturated, compacted bentonite, with particular emphasis on the role of non‐uniform stress ...

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.

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 ...

Application of Circular Economy Principles to Power Generation: Extending the Life of A Hydropower Plant by Pumped Hydro Energy Storage

Sustainable Development, EarlyView.
ABSTRACT The application of circular economy, which aims to maximize efficiency and reduce waste, to renewable energy sources necessitates, given the intermittent nature of the latter, robust energy storage solutions to ensure grid stability and avoid wasting energy.

Testing and modeling reinforced 3D concrete printing

Structural Concrete, EarlyView.
Abstract 3D Concrete Printing (3DCP) provides several advantages, including construction productivity and sustainability, although the presence of cold joints reduces structural performance, particularly in zones subjected to tensile stresses. In addition, it is difficult to reinforce 3DCP structures with conventional steel rebars, generally used to ...
