River dams provide many benefits, including flood control. However, due to constantly
evolving channel morphology, downstream conveyance of floodwaters following dam …

The bed of fluvial ecosystems plays a major role in global biogeochemical cycles. All fluvial
sediments migrate and although responses of aquatic organisms to such movements have …

River dunes are wavelike features in sandy riverbeds that move slowly in a downstream
direction. These bedforms are shaped by the interaction between flowing water and sand …

River dunes, dynamic bedforms in the river bed, limit navigable depths during low flows and
increase bed roughness. To predict the navigable depth or where maintenance dredging is …

Dune dimensions in sand‐bedded rivers are often thought to scale with flow depth (h), with
height (H) scaling as 1/6h and length (L) as 5h, even though substantial scatter about the …

Fluvial cross strata are depositional products of bedform migration that record formative flow
and sediment transport conditions on planetary bodies. Bedform evolution varies with …

In this study, measured outcrop sections and geolocated photomosaics are integrated with
areal mapping of channel dimensions, degree of amalgamation, calculations of channel‐to …

Fluvial instabilities originate from an interplay between the carrier fluid and the erodible
loose boundary at their interface, manifesting a variety of sedimentary architectures with …

The mechanisms responsible for dune growth and decay remain a major unknown in river
dynamics. Two theories have been supported by experiments and numerical models. A …

Fine-grained sediment (grain size under 2,000 μm) builds floodplains and deltas, and
shapes the coastlines where much of humanity lives. However, a universal, physically based …
