Logjams Promote Floodplain Complexity and Hydraulic Resistance
Using a new model, scientists compare logjam hydraulic impact across 37 reaches observed over 11 years in the Colorado Rockies.
Mobile Bay Has More Branching Brooks Than Shown on Federal Maps
A more accurate charting of the full extent of stream networks will help land managers better protect U.S. creeks and rivers.
New Insight into Inland Water Carbon Dioxide Emissions
A process-based modeling technique reveals surprising information about carbon emissions from rivers, lakes, and reservoirs across the contiguous United States.
New Rules for Catastrophic River Avulsion
Scientists thought two factors influencing river avulsion were unrelated, but new research suggests they may be working in tandem. The findings could help predict new river pathways and improve disaster preparedness.
Physics and Biology as Likely Stream Bedfellows
Streambeds are key sites for removal of nutrients and other contaminants through microbial processes, but are limited by diffusion, which can now be modeled from streambed physical properties.
Elementary, My Dear: Al & Be Give Evidence of Past Climate Change
10Be and 26Al concentrations in river sand reveal an increase in erosion rate in the Brazilian Highlands consistent with the Mid-Pleistocene Transition, a major climatic shift that occurred about 1 million years ago.
Improvements to Measuring the Ups and Downs of the Landscape
If you are a jazz fan, you may be familiar with Ella Fitzgerald singing ‘How deep is the ocean, how high is the sky’. Using data from the Shuttle Radar Topography Mission we now know how high the land really is.
How an Ocean-Sized Lake May Have Formed on Ancient Mars
The catastrophic collapse of Mars’s atmosphere may have melted its polar ice cap, creating an ice-covered southern sea.
On the Wisconsin-Iowa Border, the Mississippi River Is Eroding Sacred Indigenous Mounds
A multimillion-dollar bank stabilization project could protect historic sites dating back thousands of years.
