He conducted river morphology research based on systematic and reproducible measurements, pushing fluvial hydrology to become a more quantitative science.
Geomorphology: fluvial
The Unpredictability of Floods, Erosion, and Channel Migration
A new algorithm incorporates randomness into stream channel formation and suggests the approach represents regions with variable flood magnitudes better than standard models.
On Integrating Sedimentology and Hydrogeology in Streambeds
A new modeling blueprint seeks to unify sedimentology, hydrology, and hydrogeology in the modeling of streambeds.
Deciphering Deluges
New modeling approach reexamines two key assumptions about flooding.
What Controls the Shape of Steep Mountain Streams?
The shape of steep river streams changes systematically with channel slope, but field data and theoretical analysis reveal that slope is not the sole factor in setting a channel’s form.
A New Model for River Meanders
A river’s twists and turns are shaped by its past flood events.
How Do Rivers Flow over Bedrock?
A study questions whether the hydraulics of rivers that lack loose sediments along their bottoms can be accurately depicted by standard equations for flow over sediment.
Lab Tests Probe the Secrets of Steep and Rocky Mountain Streams
Researchers built a glass-encased test environment that helps them assess streamflow without the confounding factors introduced by bed forms.
Stream Network Geometry Correlates with Climate
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
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.
