Today’s Highlights
A strong day for remote sensing and hydrologic modeling. A new operational system delivers near real-time global riverine sediment flux from satellite imagery using SWOT-derived discharge. Meanwhile, baseflow data assimilation is shown to substantially improve peak flow prediction by correcting subsurface flow representation. A global analysis of soil organic carbon reveals high-latitude hotspots most vulnerable to climate change.

Operational Near Real Time Global Riverine Sediment Flux Estimates From Space
Authors: L. V. Lucchese, R. Daroya, T. Simmons, P. Prum, N. Tebaldi et al.
Journal: Geophysical Research Letters · DOI: 10.1029/2025gl120407
Matched topics: river, surface water
We present global estimates of riverine sediment flux derived from an open‐source suite of algorithms using the Harmonized Landsat Sentinel (HLS) and discharge products. We estimated Sediment Concentration (suspended sediment concentration [SSC]) via neural networks, trained and tested on matchups of in situ and HLS data, obtaining a median error of 13 mg/L and R² of 0.53. We paired SSC estimates with Surface Water and Ocean Topography (SWOT)‐derived discharge and GRADES‐hydroDL separately to compute sediment flux globally.
The Role of Baseflow Data Assimilation in Hydrologic Modeling and Peak Flow Prediction
Authors: Parnian Ghaneei, Ehsan Foroumandi, Hamid Moradkhani
Journal: Geophysical Research Letters · DOI: 10.1029/2025gl121456
Matched topics: hydrologic model, runoff, streamflow, surface water
Recent studies have revealed that subsurface water storage and flow pathways contribute a substantially larger share of streamflow than previously assumed. However, because representations of these subsurface contributions in most hydrologic models are uncertain and often biased, they can strongly influence simulated streamflow generation and partitioning. Here, we use Hydrologic Generative Ensemble Data Assimilation method to merge baseflow observed data with the outputs of a hydrologic model to improve both low-flow and high-flow predictions.
Hydroclimatic Variability Shapes Long‐Term Water Balance
Authors: Antônio Alves Meira Neto, André S. Ballarin, Paulo Tarso S. Oliveira, Guo‐Yue Niu
Journal: Geophysical Research Letters · DOI: 10.1029/2025gl121486
Matched topics: seasonal
Long‐term water availability is commonly interpreted through mean precipitation and potential evapotranspiration, yet hydroclimatic variability spans seasonal to event scales and may influence water partitioning beyond what mean climate alone captures. Although the aridity index explains much of the spatial variability in evaporative fraction, systematic departures from classical relationships suggest that additional modes of variability shape long‐term water balance. Here, using large‐sample observations, we show that hydroclimatic variability is a key driver.
Capacity Building on the Use of High-Resolution Climate Change Projections for Impact Studies over Southeast Asia

Evaluating the Financial Impact of Soil Moisture Measurements for Livestock Producers in the Upper Missouri River Basin
Authors: Jacklynn K. Beck, Gavin A. White, Steven M. Quiring
Journal: Bulletin of the American Meteorological Society · DOI: 10.1175/bams-d-25-0091.1
Matched topics: river, drought
Droughts pose a significant financial risk to the agricultural sector in the United States. Livestock producers are particularly affected, as drought reduces forage availability and increases costs. To mitigate these impacts, the USDA Livestock Forage Disaster Program (LFP) provides direct payments to qualifying producers based on drought severity. In-situ observations play a key role in assessing drought severity by providing localized information on conditions. Station density in the Upper Missouri River Basin is limited, and this study evaluates the financial impact of expanding soil moisture monitoring networks.

Global hotspots of particulate organic carbon losses under climate change
Authors: Siyi Sun, M. Francesca Cotrufo, R. A. Viscarra Rossel, Carsten W. Mueller, Morimaru Kida et al.
Journal: Nature Communications · DOI: 10.1038/s41467-026-71321-2
Matched topics: climate change
Soil organic carbon (SOC) comprises particulate (POC) and mineral-associated organic carbon (MAOC), which differ in formation, stabilization, and loss mechanisms. While the current global distribution of POC and MAOC is characterized, their vulnerability under future climate scenarios remains unclear. Using 3284 topsoil (0-30 cm) observations from six continents, we identify high-latitude soils as global hotspots of SOC vulnerability under shared socioeconomic pathway scenarios (SSP126, SSP245, SSP585), with POC showing greater sensitivity to climate change than MAOC.
