Antidunes on the Beach
Antidune
https://en.wikipedia.org
An antidune is a bedform found in fluvial and other channeled environments. Antidunes occur in supercritical flow, meaning that the Froude number is greater ...
Antidune Cross
https://pubs.geoscienceworld.o
ABSTRACT. Cross-bedding and lamination was formed by antidunes in a large laboratory flume. When the flow was stopped, the bed-forms in the fine sand were ...
Antidune lithofacies
https://www.geological-digress
Antidunes and associated UFR bedforms are common in many modern open channel flows. The potential for antidune preservation probably depends on ...

Lithofacies beyond supercritical antidunes
https://www.geological-digress
The flow conditions that produce antidunes are part of a hydrodynamic spectrum where increasing velocities (and energies) give rise to a ...
Particle
https://www.cambridge.org
Among the bedforms at supercritical flow conditions, antidunes are the shortest in wavelength (of the order of the flow thickness), and they are ...
Schematic presentation of antidunes characterized by a ...
https://www.researchgate.net
Antidunes are fluvial bedforms that form in rivers with supercritical flows. The water surface over antidunes is strongly in phase with the bed surface, and the ...
Stability of Fluvial and Gravity
http://ui.adsabs.harvard.edu
Antidunes develop as a consequence of interface (free surface) deformation and sediment transport feedback in supercritical flows.
The formation of dunes

However, the mechanism of the formation of dune and antidune is somehow di!erent from that of a ripple. As stated by Graf [8], the alluvial bed form for &low ...
