Atmospheric rivers could increase flood risk by 80 per cent
November 9, 2017 11:03 AM - University of Oxford

The global effect and impact of atmospheric rivers on rainfall, flooding and droughts has been estimated for the first time – revealing that in some regions the risks can be enhanced by up to 80 percent. The work, of which Oxford University is a key partner, also considers the number of people affected by these atmospheric phenomena across the globe.

Floods Are Necessary for Maintaining Healthy River Ecosystems
November 27, 2017 11:59 AM - Oregon State University

Flooding rivers can wreak havoc on homes and roads but are necessary for healthy ecosystems, research at Oregon State University suggests.

Sustainable dams — are they possible?
December 11, 2017 02:41 PM - Colorado State University

Humans have been altering natural waterways for centuries, but only in the last several decades have dams raised ecological concerns.

N. LeRoy Poff, professor of biology at Colorado State University, studies the ecological impact to rivers from human-caused changes, such as dam building, and how these modified river systems can be managed for resilience.

Cave bacteria: A window to the past, even to distant worlds
July 27, 2017 08:27 AM - Thompson Rivers University

Each time she looks through a microscope to better understand cave bacteria, Richenda McFarlane may also be staring at life that’s centuries old or perhaps even something from another planets.

She’s getting to play researcher, time traveler and astronaut all at the same time.

Rivers Carry Plastic Debris Into The Sea
October 17, 2017 11:10 AM - Helmholtz Centre for Environmental Research - UFZ

Every year, millions of tonnes of plastic debris ends up in the sea - a global environmental problem with unforeseeable ecological consequences. The path taken by plastic to reach the sea must be elucidated before it will be possible to reduce the volume of plastic input. To date, there was only little information available on this. It has now been followed up by an interdisciplinary research team who were able to show that plastic debris is primarily carried into the sea by large rivers.

U.S. Waterways Are Getting Saltier, With Possible Effects on Drinking Water
January 10, 2018 09:52 AM - Yale Environment 360

Streams and rivers across much of the U.S. are getting saltier and more alkaline due to an uptick in the use of road deicers and fertilizers in recent decades, according to a  50-year-long analysis of 232 monitoring sites by the U.S. Geological Survey.

US Rivers and Streams are Compromised by Increasing Salt Loads
January 8, 2018 03:53 PM - Cary Institute of Ecosystem Studies

Human activities are exposing US rivers and streams to a cocktail of salts, with consequences for infrastructure and drinking water supplies. So reports a new study in the Proceedings of the National Academy of Sciences that is the first to assess the combined, long-term changes in freshwater salinity and alkalization across the country.

Researchers explore ways to remove antibiotics polluting lakes and rivers
October 12, 2017 08:11 AM - University of Saskatchewan

Pharmaceuticals, including antibiotics, are an increasingly common pollutant in water systems, said Catherine Hui Niu, associate professor in the Department of Chemical and Biological Engineering at the University of Saskatchewan.

When to fish: Timing matters for fish that migrate to reproduce
November 30, 2017 09:35 AM - University of Washington

It’s no secret that human activities affect fish, particularly those that must migrate to reproduce. Years of building dams and polluting rivers in some regions have left fish such as salmon struggling to return to their home streams and give birth to the next generation.

‘Brazil Nut Effect' Helps Explain How Rivers Resist Erosion, Penn Team Finds
November 21, 2017 10:49 AM - University of Pennsylvania

Pop the top off a can of mixed nuts and, chances are, Brazil nuts will be at the top. This phenomenon, of large particles tending to rise to the top of mixtures while small particles tend to sink down, is popularly known as the “Brazil nut effect” and more technically as granular segregation.
