In gravel-bed rivers, sediment transport is commonly intermittent, with low background rates of motion punctuated by short, rare events of elevated activity. Although the physical mechanisms explainin...

With increasing river flow, sand dunes on the riverbed initially grow and eventually flatten out. However, flume experiments show that dune height distributions under high flow are bimodal, suggesting...

Using high-resolution river bed topography, surface roughness metrics are quantified across various spatial scales A comprehensive description river bed topographic variability requires the concu...
