Sediment supply controls equilibrium channel geometry in gravel rivers

AM Pfeiffer, NJ Finnegan… - Proceedings of the …, 2017 - National Acad Sciences
In many gravel-bedded rivers, floods that fill the channel banks create just enough shear
stress to move the median-sized gravel particles on the bed surface (D 50). Because this …

The influence of riparian woody vegetation on bankfull alluvial river morphodynamics

GT Török, G Parker - Scientific reports, 2022 - nature.com
Exploring the effects of bank vegetation on fluvial morphodynamics has long been an
