Running Water on Topographic Data to Better Delineate Channels
Two-dimensional hydraulic simulations are a powerful tool to identify process domains such as channels, hillslopes, and floodplains in high-resolution topographic data.
Endangered Rivers Plagued by Pollution, Climate Change, and Outdated Management
The annual list of America’s Most Endangered Rivers includes practical calls to action to turn the tide on threatened U.S. waterways.
Incredible Journeys on the Crown of the Continent
Living in Geologic Time: The making, breaking, and backpacking of North America’s Continental Divide.
A Sharper Look at the World’s Rivers and Catchments
Digital hydrographic maps have transformed global environmental studies and resource management. A major database update will provide even clearer and more complete views of Earth’s waterways.
A New Index to Assess Multiple-Reservoir Effects on Peak Floods
A simple, yet quantitative, index is demonstrated to quantify reductions in the peak flood resulting from multiple reservoirs, arranged in series along the same river reach.
Pharmaceuticals Found in Rivers on All Continents
A quarter of 258 observed rivers had unsafe levels of at least one drug. The findings raise concerns about Earth’s aquatic life and the global threat of antimicrobial resistance.
Forest Fires Could Boost Western U.S. Water Supplies
Streamflow in the West has been below average since the early 2000s, but a new analysis shows that streams aren’t as dry as expected.
Lake Michigan’s Salinity Is on the Rise
Road salt is primarily to blame for the shift, though the water remains within safe levels for now.
How Climate Change Shaped the Amazon’s Land and Life
Ice Age climate swings shaped the equatorial basin’s terrain—and possibly its ecology—faster than previously thought.
