A Numerical Study of the Effects of Density Contrast on Flow, Turbulence, and Mixing at the Negro/Solimoes Confluence, Brazil

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Eddy‐resolving numerical simulations are conducted to investigate the effects of density contrast between the confluent flows on hydrodynamics, coherent structures and mixing downstream of the confluence between the Negro and Solimões Rivers, Brazil, which is characterized by both a large discharge (>100,000 m3/s) and a large aspect‐ratio (W/D

Mechanisms of Vegetation Community Self‐Organization Driven by Water Availability in Arid Northwest China

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Precipitation is scarce in arid regions, making water redistribution a key driver of vegetation patterns, especially for non‐zonal vegetation in oases. Nevertheless, the coupling and mutual feedback mechanism between water and vegetation distribution is complex, and it has not been fully addressed. Taking an arid region of Northwest China as a

Hardness Toxicity and Multi‐Route, Multi‐Demographic Health Risks of Nitrate‐Contaminated Groundwater: A Call for Sustainable Environmental and Public Health Protection

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Groundwater contamination by nitrate and hardness poses critical challenges to environmental sustainability and public health across many regions. This research pioneers an integrated assessment of nitrate multi‐route exposure for six‐age groups and hardness toxicity in Ghana.

Leveraging the TabPFN Algorithm for High‐Resolution Mapping of Groundwater Bicarbonate and Its Scaling Risk Across China

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Large‐scale groundwater quality prediction is often constrained by sparse sampling, limiting the reliability of spatial assessments. This study introduces Tabular Prior‐data Fitted Network (TabPFN), a machine learning model based on prior‐fitting networks, to address this challenge and enable high‐precision mapping of groundwater bicarbonate ...

Efficiency of Spatial Subsidies Under Information Constraints: A Case Study

Agricultural Economics, Volume 57, Issue 3, May 2026.
ABSTRACT This study compares the efficiency of homogeneous versus spatially heterogeneous subsidies in developing agricultural plans compatible with bird sustainability. Using the plains of Lleida as a case study—where incentives for agricultural intensification threaten a bird community‐we employ a spatially explicit model that simulates crop yields ...

Thermal Buffering, Heat Advection and Crustal Thinning in the Ryoke Metamorphic Complex, Yanai, Southwest Japan

Journal of Metamorphic Geology, Volume 44, Issue 4, Page 287-310, May 2026.
ABSTRACT The metamorphic zoning and geothermobarometry of the Ryoke metamorphic complex in the Yanai area, southwest Japan, show that its thermobaric structure was buffered by the dehydration melting of biotite. The temperatures over most of the area covered by the three high‐grade zones (8.5‐ to 19.0‐km depth) are consistent with those of the ...
