Empowering teachers and fostering pupil climate action in Welsh primary schools

open access: yesThe Curriculum Journal, EarlyView.
Abstract The Curriculum for Wales intends to help students understand and address climate change, but relies on teachers' knowledge and implementation thereof. This article focuses on “The Lifecycle of My Clothes”, a unit of work (UoW) developed by academics and practitioners. The UoW aimed to increase students' awareness of the environmental impact of

Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

Numerical investigation of the correlations of hydraulic and elastic characteristics in diverse carbonate rock types

open access: yesDeep Underground Science and Engineering, EarlyView.
We use the linear Boolean model and the discrete Fourier transformation approach to generate various carbonate rocks. The lattice Boltzmann method and the finite element method are applied to calculate permeability and elastic wave velocity, respectively.

Numerical investigation on the influence of mesoscopic deformation on contact area and hydraulic aperture to fracture seepage

open access: yesDeep Underground Science and Engineering, EarlyView.
Fluid flow through a single fracture is commonly described by the cubic law. However, deviations from this model are expected because natural fracture surfaces are rough and in contact with each other in discrete regions. In this study, the interactions between fracture closure, contact area, and hydraulic characterization of mesoscopic‐scale rough ...

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

open access: yesDeep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.
