Spatiotemporal Assessment of Groundwater Interactions With a Regulated River: A Case Study of the Nechako River, Canada

River Research and Applications, EarlyView.
ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

River Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Assessment of spatiotemporal trends in groundwater depth and salinity through GIS‐based geostatistical analysis: The case of Aksu Irrigation System in Antalya, Türkiye

River, EarlyView.
The study revealed that while groundwater depth trends were generally risk‐free, electrical conductivity showed localized risks in 38% of the Aksu Irrigation System. Overall, 25% of the area was classified as risky. The integrated GIS‐based approach provides a rapid, objective, and cost‐effective tool for precision water management. Abstract Continuous

Water Losses and Environmental Efficiency in Urban Water Supply Systems: A Comparative Assessment for Spain and Portugal

Sustainable Development, EarlyView.
ABSTRACT Water losses are a critical environmental and operational challenge, especially in regions exposed to increasing water stress. This study assesses the environmental productivity of municipal water supply services in Spain and Portugal during the period 2014–2022, explicitly treating losses as an undesirable output.

Income Mobility, Automation, and Occupational Licensing

Southern Economic Journal, EarlyView.
ABSTRACT Technological change has long been tied with distributional concerns due to displacement against certain skills on labor markets. Short‐run dislocations could create scarring in the long run. For example, shifts against less skilled workers with children could limit their ability to improve the inter‐generational income mobility of their ...

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

steel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Seepage and deformation characteristics of sliding-zone soils under cyclic seepage pressure

Numerous incidents and failures of landslides in reservoir areas are attributed to water level fluctuations, which frequently induce cyclic changes in seepage pressure within the soil masses.

Foamed Concrete Sealing Materials for Coal Seam Gas Drainage Boreholes: A Review

Safety Science and Technology, EarlyView.
This study investigates the sealing performance of foamed concrete in gas drainage boreholes. By comparing leakage pathways (a, c) with sealed systems (b, d), the research demonstrates how foamed concrete effectively fills mining‐induced fractures and resists deformation.

Contrastive Self‐Categorization as a Resource for Defending Cultural Stereotypes

Symbolic Interaction, EarlyView.
This study explores how speakers defend morally sanctionable cultural stereotypes from challenges in adult second language classrooms. Within the conversation analysis and membership categorization analysis frameworks, I examine two extended video‐recorded class discussions in which students maintain face‐threatening, stereotypical portrayals of ...
