- 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...
- (typically
water or wind).
Examples of
these bedforms are ripples, dunes,
antidunes, sand waves, hummocks, bars, and
delta slopes.
