When Snowpacks Shrink: Declining Weathering and Export Rates but Rising Stream Solute Concentrations in Warming Mountains

Hydrological Processes, Volume 40, Issue 5, May 2026.
In a snow‐dominated headwater catchment, snow‐dependent water storage controls silicate weathering and solute export. In the driest year with the least snow water equivalent (SWE), rates of silicate weathering and export rates of weathering products were about half and a third of those in the wettest year with the highest SWE.

Fault‐Mediated Groundwater‐Surface Water Mixing Amplifies Hydrochemical/Hydrological Dynamics in a Semi‐Arid Volcanic Lake Basin

Hydrological Processes, Volume 40, Issue 5, May 2026.
Isotopes data help to understand the GW‐SW connectivity, the recharge elevations, and evaporation in a volcanic lake basin. ABSTRACT Understanding groundwater (GW) to surface water (SW) connectivity (i.e., the exchange of water and solutes between aquifers and surface bodies) is increasingly important under changing climate conditions, where ...

Stemflows and Preferential Flows: A Historical Review and Challenges for the Future

Hydrological Processes, Volume 40, Issue 5, May 2026.
Possible implementation of stemflow in the MIPS model where all water in the system is represented as particles in pathways of specified velocity. Stemflow (green particles) can be treated as a localised input with probabilities of entering higher velocity pathways than throughfall, depending on the input rates.

Patterns of River Flow Regulation Across the World's Climate Regions

Hydrological Processes, Volume 40, Issue 5, May 2026.
We quantify the Impoundment Ratio (IR) for 16 060 dams worldwide to assess how reservoir capacity relative to natural runoff varies across climate regions. One‐third of dams have IR ≥ 1, with the highest values in arid and semi‐arid zones and clear national contrasts within similar climates.

Comparing ERA5‐Land and BR‐DWGD Datasets and Their Impacts on Vadose‐Zone Hydrological Modelling in the Brazilian Cerrado

Hydrological Processes, Volume 40, Issue 5, May 2026.
We compared ERA5‐Land and BR‐DWGD datasets for climate trend analysis and vadose zone hydrological simulations in the Brazilian Cerrado. Bias correction improved the representation of daily meteorological variables in ERA5‐Land. Although long‐term climate change signals were consistent between the datasets, inherent errors in ERA5‐Land propagated ...

Trends in nitrate levels in Iowa's community water systems (2000–2022): Characteristics of systems vulnerable to maximum contaminant level exceedances and future regulatory scenarios

Journal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract This study examines trends in nitrate contamination in Iowa's community water systems (CWS) from 2000 to 2022, focusing on the characteristics of CWS that are most vulnerable to elevated nitrate levels and those likely to be impacted by a lower maximum contaminant level (MCL).

Spatiotemporal Droughts Propagation and Direct Driving Variables Under Climate Change Projections: A Case Study of Tunisia

International Journal of Climatology, Volume 46, Issue 6, May 2026.
Drought spatiotemporal propagation and direct driving variables are assessed at multiple time steps with high spatial resolution using various drought indices (SPI, SPEI and SPDI) and entropy based mutual information under an ensemble of climate change projections over Tunisia. ABSTRACT Projecting drought occurrence and spatiotemporal propagation under
