Stream Network Geometry Correlates with Climate

by Terri Cook 6 April 20176 June 2022

A "big data" analysis of nearly 1 million river junctions in the contiguous United States shows that branching angles in dendritic drainages vary systematically between humid and arid regions.

Boulders Limit Transport of Sand and Gravel in Steep Rivers

by A. Branscombe 6 January 20176 March 2023

Mountain rivers and streams actively reshape landscapes by eroding material from uplands and depositing it in lowlands. Scientists can now predict this transport in very steep streams.
