Short summary
What controls the size and shape of a river – its width, depth, and slope? The cross-sectional channel geometry of gravel-bedded rivers is understood to be a function of the river's fluid shear stress and the weight of the average particle on its bed; however, there is no satisfactory explanation for sand-bedded rivers. We analyze global datasets and individual river profiles and propose that accounting for riverbank cohesion could allow for an explanation for sand-bedded river channel geometry.
