Probabilistic characterization of seepage‐induced tunnel face failure via a two‐phase double‐point material point method

Deep Underground Science and Engineering, EarlyView.
To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Numerical investigation of natural fracture activation and leakage risk during CO2 sequestration in depleted sandstone reservoirs

Deep Underground Science and Engineering, EarlyView.
This study investigates the hydro‐mechanical response and fracture evolution in depleted sandstone reservoirs during CO2 injection, considering both direct wellbore injection and hydraulic‐fracture‐assisted injection. The graphical abstract illustrates how CO2 injection induces dynamic stress redistribution, leading to natural fracture activation ...

Coupled Thermo-Hydro-Mechanical Modeling of CO₂ Leakage Through a Micro-Annulus in an Abandoned Wellbore

Energies
Abandoned wells pose a significant leakage risk for geological carbon (CO2) storage because defects at the casing–cement interface can create preferential pathways for upward CO2 migration.

From Policy Presence to Policy Performance: Adaptive Improvisation and the Everyday Politics of Plastic Burning Bans in Rural Indonesia

Environmental Policy and Governance, EarlyView.
ABSTRACT Open burning plastics is a major environmental health hazard in low‐ and middle‐income countries, releasing toxic pollutants and exacerbating climate change. Although Indonesia prohibits plastic burning, enforcement in rural settings remains fragile.
