It’s Time to Revise Estimates of River Flood Hazards
Accurately assessing flood hazards requires a better understanding of the feedbacks between natural and human influences on the characteristics of rivers.
Representing Estuaries and Braided Rivers as Channel Networks
The human eye is quite good at identifying channel networks among the rich patterns exhibited by estuaries and braided rivers, but computers have a harder time doing so. Could they do better?
River Ice Is Disappearing
Over the past 3 decades, the persistence of river ice has decreased by almost a week. The decrease in ice has important implications for ecology, climate, and the economy.
Science Gets Up to Speed on Dry Rivers
Nonperennial rivers are a major—and growing—part of the global river network. New research and science-based policies are needed to ensure the sustainability of these long-overlooked waterways.
Europe’s Rivers Are the Most Obstructed on Earth
By analyzing satellite imagery of rivers worldwide, researchers have pinpointed over 35,000 obstructions like dams and locks that affect an environment’s ecology, hydrology, and water resources management.
Scientists Search for Deltas on Saturn’s Largest Moon
Saturn’s moon Titan has rivers that empty into seas…but where are the deltas?
Remote Landslide Puts Fraser River Salmon on Shaky Ground
An alliance of First Nations, provincial, and federal leaders worked with scientists, engineers, and emergency responders to rescue critical salmon stocks in western Canada.
The Shape of Watersheds
Streams in flatter watersheds have carbon cycles more sensitive to temperature increases.
New Isotope Model Predicts Denitrification from Riparian Zones
A new model quantifies the relative contributions of denitrification and other processes of nitrogen uptake, such as by plants, from groundwater in riparian areas around streams.
