Large boulders help shape huge canyons, researchers find

Anyone who enjoys whitewater rafting in places like the Colorado River owes a debt of gratitude to the enormous boulders that create the foaming undulation known as rapids, and new research appears to shed more light on how ...

Researcher suggests rivers may cause earthquakes

Ryan Thigpen, an assistant professor in the Department of Earth and Environmental Sciences in the University of Kentucky College of Arts and Sciences, has co-authored a paper that describes how river erosion may lead to ...

Chemical weathering controls erosion rates in rivers

Chemical weathering can control how susceptible bedrock in river beds is to erosion, according to new research. In addition to explaining how climate can influence landscape erosion rates, the results also may improve scientists' ...
