Mechanism and Application of Electrical Resistivity Responses in Annular Adsorbed Water Films: Insights From Capillary Theory

This study proposes a physically constrained pore-scale model for strongly water-wet low-resistivity reservoirs that attributes anomalous conductivity to continuous adsorbed water films on pore walls, utilizing a combined high-pressure mercury intrusion and nuclear magnetic resonance approach to quantify film water content and establish a dual-network conductivity model for accurate water-saturation evaluation.

Polycyclic Aromatic Hydrocarbon Derivatives in an Oil-Impacted African River System: Distribution, Source Characteristics, Bioaccumulation and Human Health Risks in the White Nile, South Sudan

This study provides the first comprehensive assessment of polycyclic aromatic hydrocarbon derivatives in the White Nile near South Sudan's Melut oil fields, revealing that petroleum-related nitro-PAHs dominate the contamination, bioaccumulate in commercially important fish species, and currently pose low carcinogenic risks despite significant ecological concerns regarding their persistence and toxicity.

A Climate Gentrification Assessment Framework for Low-Lying Coastal Cities: Evidence from Lagos, Nigeria

This study challenges the elevation-centric understanding of climate gentrification by proposing and applying a new assessment framework to Lagos, Nigeria, which demonstrates that disparities in infrastructure resilience and investment, rather than geographical height, drive housing-market transformation and socio-spatial inequality in low-lying coastal cities.

Comparison of Production-Based and Direct Measurement Approaches for Estimating Methane Emissions from Underground Coal Mines

Using a high-resolution dataset from four Polish underground coal mines, this study demonstrates that direct methane measurements provide more robust and temporally accurate emission estimates than production-based factors, while also showing that applying these factors to net rather than gross coal production reduces estimation errors.

Simulation by CORMIX of the dispersion at sea of brine discharges from the CORSO desalination plant - Algeria

This study utilizes CORMIX simulations to evaluate the brine dispersion from the CORSO desalination plant in Algeria, revealing that the current diffuser design is inadequate and recommending increased discharge velocity, repositioning of the outfall, and pre-dilution measures to ensure sustainable environmental management.

Improving water quantity and quality in a mountain hard-rock watershed (La Vera, Spain) through Ancestral Nature-Based Solution for Managed Aquifer Recharge

This study demonstrates that restoring ancestral *pesqueras* (infiltration channels) in the La Vera mountain watershed serves as an effective Nature-based Solution that simultaneously enhances groundwater recharge and naturally improves water quality through subsurface hydrogeochemical conditioning, thereby validating traditional ecological knowledge as a sustainable strategy for climate-resilient water management.

A Directional and Sequential Viewshed Framework for Analysing Terrain-Controlled Visibility along an Escarpment Road

This study introduces a GIS-based framework that extends conventional viewshed analysis by quantifying the magnitude, directional asymmetry, and sequential dynamics of terrain-controlled visibility along an escarpment road, revealing significant uphill-downhill disparities and strong correlations with slope and curvature to better understand visual experiences in complex landscapes.

Weakened downslope winds and slower simulated nighttime spread of the Camp Fire under warming

Contrary to assumptions that warming only dries fuels to accelerate wildfires, coupled simulations of the 2018 Camp Fire reveal that warming actually slows nighttime fire spread and reduces the total burned area by significantly weakening the downslope winds that drive the fire.

Mid-to-Late Holocene Hydroenvironmental Constraints on Human Adaptation at Fenghuangzui Site, Hanjiang River Basin, Central China

By integrating sedimentological, geochemical, and archaeological records, this study demonstrates that the Fenghuangzui community in Central China successfully adapted to mid-to-late Holocene hydroclimatic variability through active water management and settlement reorganization, rather than succumbing to subsistence decline.
