Scientists call the area along a river where river water and groundwater mix the hyporheic zone. The circular inset illustrates some of the features of this zone, including tiny grains of sediment, water from both sources mixing, and the microbes that actively ply these waters and sediments.

Utah State University river scientists and colleagues from the U.S. Geological Survey and other universities compared four popular stream classification networks at the watershed scale for the first time, and demonstrated significant common ground among the divergent approaches. Their findings appear in PLOS ONE March 16, 2016. Credit: Utah State […]

River Kvirila at Sachkhere, Georgia. Credit: Wikipedia Enlarge Forests help remove carbon dioxide from the atmosphere by storing it in trees, but a sizeable amount of the greenhouse gas actually escapes through the soil and into rivers and streams. That’s the main finding of a paper to appear Monday in […]

Summer for most of us is a time to embrace the warmer weather, but it also provides the perfect growing conditions for a potentially lethal blue-green alga that’s found in many New Zealand rivers, and which is the subject of new research by a Victoria University of Wellington PhD graduate. […]

A sample from the Rhine near Duisburg consisting of over 65% opaque spherules in 15-fold magnification; the spherules have a diameter of 400–900 micro meters. Credit: Thomas Mani Between Basel and Rotterdam, the Rhine has one of the highest microplastics pollution so far measured in rivers, with the Rhine-Ruhr metropolitan […]

River Kvirila at Sachkhere, Georgia. Credit: Wikipedia Enlarge Scientists have discovered a surprising similarity between rivers and humans: both release more carbon dioxide when they work hard. When people are physically active, their lungs release more carbon dioxide gas than when they are at rest. Now, researchers from the University […]
