Tidal River Flood Risk Highest During Intermediate Rather Than Peak River Discharge

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Tidal rivers are defined as the tide‐influenced, salinity‐free inland reaches of estuaries. Understanding the occurrence of peak water levels (PWLs) is critical for flood risk management, yet the timing and magnitude of PWLs in tidal rivers have been little studied. We address this gap by investigating PWLs during two catastrophic floods (1954

Investigating Fine Particulate Matter in Streams Uncovers Peak Bacterial Activity in Agricultural Streams and on the Finest Particles

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract The processing of organic matter (OM) in stream ecosystems is a key component of the fluvial carbon cycle. While research has largely focused on the cycling of dissolved OM (DOM), suspended particles are increasingly recognized as active sites of OM cycling.
