Definition of Antidunes. Meaning of Antidunes. Synonyms of Antidunes

- An antidune is a bedform found in fluvial and other channeled environments. Antidunes occur in supercritical flow, meaning that the Froude number is greater...
- the dunes become flattened out, and then produce antidunes. At higher still velocity, the antidunes are flattened and most sedimentation stops, as erosion...
- increasing the overall understanding of these currents. Some of the largest antidunes on Earth are formed by turbidity currents. One observed sediment-wave...
- motion can create self-organized structures such as ripples, dunes, or antidunes on the river or stream bed. These bedforms are often preserved in sedimentary...
- plane bed High Flat laminae, +/- aligned grains (parting lineations) Antidunes Low Water in phase with bedform, low angle, subtle laminae Pool and chute...
- the cross-beds of a dune and the cross-beds of an antidune. (Dunes dip downstream while antidunes dip upstream.) The direction of motion of the cross-beds...

- sedimentary structures typical of high-velocity flow, such as dunes and antidunes. Volcanic ash already deposited on the surface can be transported as mud...
- giant current ripples are large-to-very-large subaqueous gravel dunes and antidunes. Although they once covered a significantly larger area, they cover about...
