Hydrogeochemical Appraisal and Human Health Risk Assessment of the Geogenic Fluoride Crisis in Al-Musaymir’s Drinking Water: From Neurodevelopmental Hazards to Sustainable Remediation

This pioneering study identifies a severe geogenic fluoride crisis in Al-Musaymir's drinking water, driven by Jurassic formations and posing critical neurodevelopmental risks to children, and proposes a sustainable, locally sourced limestone remediation strategy to mitigate these hazards.

Assessing the vulnerability of the Karaj aquifer with the upgraded Fuzzy DRASTIC+ model by combining water quality and land use indicators

This study introduces an upgraded Fuzzy DRASTIC+ model that integrates hydrogeological parameters with water quality and land use indicators to assess the Karaj aquifer, revealing that nearly half of the area faces high vulnerability due to intensified urban and agricultural pressures, thereby highlighting the urgent need for targeted management strategies like artificial recharge and land use control.

Spatiotemporal patterns of dissolved silica in the Yangtze River under intensive dam regulation

This study reveals that intensive dam regulation in the Yangtze River system, particularly by the Jinsha River cascade reservoirs and the Three Gorges Dam, has significantly altered dissolved silica transport by homogenizing upstream concentrations and driving a long-term decline in downstream delivery due to enhanced retention, settling, and biological uptake within impounded reaches.

Shake and Bake: Structural or Subduction Control on Sumatran Volcanism? A Statistical Approach

By integrating statistical analysis of morphometric and structural parameters with geochemical constraints, this study demonstrates that the Sumatran Fault, rather than subduction processes alone, exerts a primary control on the location and morphology of several volcanoes in Sumatra.

Monte Carlo Simulation of Earthquake Damage to Mexico City:A Cadastral Exposure Model with Voronoi-Weighted Spatio-Temporal Point Processes

This paper presents a Monte Carlo simulation model that integrates cadastral property data, ETAS seismic source clustering, and site-specific ground motion amplification to estimate future earthquake-induced monetary losses in Mexico City, revealing an average annual loss of 2.26 billion MXN and a 1-in-100-year loss of 40 billion MXN.

Shoreline Dynamics and Hydroclimatic Variability at the Ras Al-Katib Coastal Barrier, Al-Hodeidah, Yemen

This study utilizes multi-temporal satellite imagery and hydroclimatic data to reveal that the Ras Al-Katib coastal barrier in Yemen exhibits contrasting erosion and accretion patterns driven by seasonal wind forcing and alongshore sediment redistribution, despite the absence of significant long-term trends in offshore wave height or air temperature.

Bibliometric Mapping of Flood Barrier Research Trends and Collaborative Networks from Physical Infrastructure to Social Resilience 2008 to 2026

This bibliometric analysis of 210 flood barrier studies from 2008 to 2026 reveals that the field is structurally fragmented into distinct technical and socio-political streams, characterized by a temporal shift toward resilience paradigms yet hindered by limited cross-disciplinary integration and geographic bias toward developed nations.
