Amplification of downstream flood stage due to damming of fine-grained rivers
River dams provide many benefits, including flood control. However, due to constantly
evolving channel morphology, downstream conveyance of floodwaters following dam …

The quintessential s-shape in sedimentology: A review on the formation and controls of clinoform shape
I Anell - Earth-Science Reviews, 2024 - Elsevier
Clinoforms are ubiquitous depositional surfaces in sedimentary systems. The quintessential
shape, with a flat or gentle topset, sloping foreset, and gentle to flat bottomset, is …

The adaptation of dunes to changes in river flow
The dunes that cover the beds of most alluvial channels change in size and shape over time
and in space, which in turn affects the flow and sediment-transport dynamics of the river …

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

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 …

Formation of sinuous ridges by inversion of river-channel belts in Utah, USA, with implications for Mars
Sinuous ridges are important landforms on the surface of Mars that show promise for
quantifying ancient martian surface hydrology. Morphological similarity of these ridges to …
