Experiment and Numerical Simulation of Seawater Intrusion under the Influences of Tidal Fluctuation and Groundwater Exploitation in Coastal Multilayered Aquifers

Geofluids, 2019
The dynamic behavior of groundwater flow and salt transport is affected by tide and pumping in coastal multilayered aquifers. In this paper, two groups of experiments were conducted considering different constant head inland boundaries.

Ecological Challenges and Strategic Responses to China's Quantitative Rigidity of Cultivated Land Protection

Land Degradation &Development, Volume 37, Issue 16, Page 11989-12003, October 2026.
ABSTRACT Balancing food security and ecological sustainability has become a critical challenge for land governance in rapidly urbanizing countries. China has successfully maintained national cultivated land quantity through a comprehensive farmland protection regime.

Quantifying the Surface Deformation of Pingos on the Alaskan North Slope Using Interferometric Synthetic Aperture Radar (InSAR)

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 682-691, October/December 2026.
ABSTRACT Pingos are large mounds with cores formed of intrusive ice that form in periglacial landscapes. These ice structures can form in regions of discontinuous permafrost, commonly as hydraulic or open‐system pingos, or in locations of continuous permafrost, commonly as hydrostatic or closed‐system pingos.

Groundwater level fluctuation caused by tide and groundwater pumping in coastal multi-layer aquifer system

Frontiers in Marine Science
This paper considered the groundwater head fluctuation induced by tide and pumping in the coastal multi-layered aquifer system. The multi-layered aquifer system comprises an unconfined aquifer, an upper confined aquifer, and a lower confined aquifer.

Abundance of atrazine degrading genes trzN versus atzA in soil cultures and in situ degradation rates

Pest Management Science, Volume 82, Issue 10, Page 10272-10279, October 2026.
Atrazine degradation in agricultural soils showed in situ half‐lives of 36–225 days. Field and laboratory results indicate active microbial hydrolysis driven mainly by trzN. Biphasic degradation sustains long‐term persistence, maintaining the potential for groundwater contamination despite reduced immediate leaching risk.

Transport Mechanisms of Conservative Contaminants From Tidally Influenced Semi‐Confined Aquifers to the Sea

Geophysical Research Letters
Groundwater contamination in confined aquifers is an increasingly critical issue, yet the dynamic processes governing contaminant transport between semi‐confined aquifers and the ocean remain insufficiently understood. This study explores these processes

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, Volume 34, Issue 6, Page 8018-8057, October 2026.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Seasonal and Spatial Variability of Silicon Cycle in Godavari Tidal River Zone

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Dam regulation of tropical monsoonal rivers enhances seasonal contrasts in the tidal river zone (TRZ) hydrology, altering the delivery of dissolved silicon (DSi) to the coastal ocean. Here, we identify the drivers of Si cycling in the Godavari TRZ and quantify their implications for Si delivery to the Bay of Bengal (BoB). We analyzed elemental

A Catchment‐Based Global Model of River Discharge and Flow Velocity for Earth System Models

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
Abstract The representation of river flows in Earth System Models (ESMs) is crucial for understanding water resources availability, contaminant transport, and the impacts of climate change on river systems. In this study, we introduce a global runoff routing model founded on hydraulic geometry principles and hydrologic catchments, specifically designed

Offshore Groundwater Salinization and Flushing in the Canterbury Bight During Glacial‐Interglacial Cycles

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Offshore freshened groundwater (OFG) is a significant yet underexplored component of global water resources, occurring widely along many continental margins. However, its dynamics remain poorly constrained due to limited offshore observations and the absence of robust evaluation models for unambiguous emplacement interpretation.
