Amplification of downstream flood stage due to damming of fine-grained rivers

H Ma, JA Nittrouer, X Fu, G Parker, Y Zhang… - Nature …, 2022 - nature.com
River dams provide many benefits, including flood control. However, due to constantly
evolving channel morphology, downstream conveyance of floodwaters following dam …

Streambed migration frequency drives ecology and biogeochemistry across spatial scales

U Risse‐Buhl, S Arnon, E Bar‐Zeev… - Wiley …, 2023 - Wiley Online Library
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 dune dynamics during low flows

LR Lokin, JJ Warmink, A Bomers… - Geophysical research …, 2022 - Wiley Online Library
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 …

Coarse sand transport processes in the ripple vortex regime under asymmetric nearshore waves

N Fritsch, G Fromant, D Hurther… - Journal of Geophysical …, 2024 - Wiley Online Library
Large‐scale wave flume experiments are conducted in the ripple vortex regime to study near
bed coarse sand transport processes below asymmetric surface waves typical of the coastal …

The effect of sediment transport models on simulating river dune dynamics

LR Lokin, JJ Warmink… - Water Resources Research, 2023 - Wiley Online Library
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 …

Transport scaling of dune dimensions in shallow flows

RW Bradley, JG Venditti - Journal of Geophysical Research …, 2019 - Wiley Online Library
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 instabilities

S Dey, SZ Ali - Physics of Fluids, 2020 - pubs.aip.org
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 influence of transport stage on preserved fluvial cross strata

D Das, V Ganti, R Bradley, J Venditti… - Geophysical …, 2022 - Wiley Online Library
Fluvial cross strata are depositional products of bedform migration that record formative flow
and sediment transport conditions on planetary bodies. Bedform evolution varies with …

Prediction of movable bed resistance in open channels with dune forms incorporating the effects of flow separation and water temperature

J Liu, J Zhang, Z Huang, H Xu, Y Bai, Y Wang - Journal of Hydrology, 2024 - Elsevier
Flow separation behind the dune forms may have reduced the contact area between the
flows and the bed surface, in addition to producing form drag in open channels. In this study …
