A Novel In Situ Experimental Setup for Studying the Impact of Bedform Celerity on 2D Oxygen Distribution in the Hyporheic Zone of Streams

Water Resources Research
Hydrodynamic and morphodynamic forces interacting across the sediment‐water interface control the biogeochemistry in the hyporheic zone. When investigating the redox zonation within streambeds, dissolved oxygen (O2) is considered a key solute to the ...

Using Machine Learning to Predict Phytoplankton Blooms in the Salish Sea

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Strong phytoplankton blooms occur every spring in the Salish Sea, but vary significantly, spatially and temporally. Natural variability and climate change make the prediction of the bloom challenging, as they affect both atmospheric drivers and nutrient interactions that contribute to the growth of phytoplankton. Understanding these drivers is

Global River Discharge Projections From a Large Multi‐Model Ensemble of CMIP6 and ISIMIP3b Simulations

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Rivers are central to the global hydrological cycle, supporting ecosystems and human water use. River discharge, one of the best observed hydrological variables, is expected to change under anthropogenic warming with potentially devastating consequences.

Fall Soil Moisture Modulates Snow‐Streamflow Dynamics in the Colorado River Basin

Water Resources Research
The Colorado River Basin (CRB) has experienced a prolonged drought since 2000, with recent years showing a weakened relationship between snowpack conditions and streamflow.

Riverine Biogeochemical Exports From Major Watersheds to the Northwest Patagonian Estuarine Network

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract River discharge considerably influences marine ecosystems through hydrological and biogeochemical drivers. Measuring baseline variability of riverine inputs, and their relation to anthropogenic land‐use impacts and global climate stressors affecting watersheds is therefore crucial for managing coastal marine ecosystems.

Landscape and Storm Characteristics Influence DOC and Nitrate Mobility and Riverine Export Magnitude in Two Arctic Catchments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract Intensifying Arctic hydrological cycles and permafrost thaw alter the magnitude and timing of lateral solute fluxes to rivers, yet interactions among hydrological, biogeochemical, and landscape controls on carbon and nutrient export remain unclear.

Multi‐Model Ensemble and Reservoir Computing for River Discharge Prediction in Ungauged Basins

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Despite the necessity for accurate flood prediction, many regions lack sufficient river discharge observations. Although numerous models for daily river discharge prediction exist, achieving high accuracy, interpretability, and efficiency under data‐scarce conditions remains a major challenge.

Riverine Nitrate Fate and Transport in the Great Lakes Basin Using the Community Land Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Agriculture and urbanization have profoundly altered the terrestrial nitrogen cycle, leading to widespread water quality degradation. Nitrogen leached from managed soils is transported and transformed through river networks, influencing downstream nutrient dynamics and ecosystem functioning.

A Roadmap for Identifying and Interpreting Physical Processes and National Water Model Prediction Bias Associated With Baseflow Index Regimes Across the Contiguous United States

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Understanding how groundwater–surface water interactions shape streamflow variability is critical for diagnosing low flow behavior and prediction bias in continental scale hydrologic models. We present a process informed framework that links observed baseflow (BF) dynamics, watershed attributes, and National Water Model (NWM) performance ...

Beyond Buffers: Subwatershed Landscape Cover Controls Stream Nutrient Export in Newly Urbanizing Areas

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Urbanization is increasing at a global scale. Rapid urbanization is often accompanied by elevated nutrients, putting downstream habitats at risk of eutrophication and harmful algal blooms. Despite these critical consequences, most urban research compares urban systems to pristine environments or focuses solely on nutrient concentrations.
