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 …

Dunes in the world's big rivers are characterized by low-angle lee-side slopes and a complex shape

J Cisneros, J Best, T van Dijk, RP Almeida… - Nature …, 2020 - nature.com
Dunes form critical agents of bedload transport in all of the world's big rivers, and constitute
appreciable sources of bed roughness and flow resistance. Dunes also generate …

Bedload transport: beyond intractability

B Gomez, PJ Soar - Royal Society Open Science, 2022 - royalsocietypublishing.org
Scrutiny of multifarious field and laboratory data amassed over nine decades reveals four

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 …

Quantification and classification of a giant fluvial-distributive system-the Triassic Mungaroo Formation, NWS, Australia

THD Payenberg, BJ Willis, P Sixsmith, SD Connell… - Earth-Science …, 2024 - Elsevier
When producing reservoirs in fluvial deposits, it is notoriously difficult to define pore volumes
connected to completed well intervals from sparse subsurface data. It is equally difficult to …

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 …

Preserved fluvial cross strata record bedform disequilibrium dynamics

KCP Leary, V Ganti - Geophysical Research Letters, 2020 - Wiley Online Library
Fluvial cross strata are an archive of ancient river morphodynamics. Controls on their
preservation are well documented for bedforms equilibrated with prevailing flows; however …

The pace of fluvial meanders on Mars and implications for the western delta deposits of Jezero crater

MGA Lapôtre, A Ielpi - AGU Advances, 2020 - Wiley Online Library
Although there is little doubt that rivers once flowed on Mars' surface, how sustained and
frequent their flows were remains enigmatic. Understanding the hydrology of early Mars …

Model for the formation of single‐thread rivers in barren landscapes and implications for pre‐Silurian and Martian fluvial deposits

MGA Lapôtre, A Ielpi, MP Lamb… - Journal of …, 2019 - Wiley Online Library

of narrow and deep single‐thread channels by strengthening riverbanks. Consistent with …

Migrating subaqueous dunes capture clay flocs

SI de Lange, A van der Wilk, C Chassagne… - … Earth & Environment, 2024 - nature.com
Recent research highlights the abundance of floccule (flocs) in rivers, formed by aggregation
of clay particles with organic matter. These flocs affect the transport and the eventual fate of …
