Flood and Megaflood Processes and Deposits: Recent and ...
Schematic model of the formation of antidune stoss-side strata around an ice
block. (a) Flow becomes supercritical just down-flow of the ice block, generating
an upstream-migrating standing wave. (b) Plan view of the upstream-migrating ...

Rivers and Floodplains: Forms, Processes, and Sedimentary Record
Thus, the term antidune was poorly chosen, although it is probably here to stay.
gd Kennedy (1963) showed experimentally and theoretically that the minimum
wavelength L of watersurface waves and two-dimensional antidunes is given by
L ...

Earth Surface Processes, Landforms and Sediment Deposits
(A) A standing water-surface wave and developing antidune. (B) An asymmetrical
water-surface wave and antidune, with flow separation on the upstream side of
the antidune prior to wave breaking. (C) A breaking wave. (D) An asymmetrical ...

Sedimentary structures, their character and physical basis
amplified forms, eqs. (10.29) and (10.30), of Kennedy's (1961) eq. 10.28 for
antidune wavelength (Fig. 10-18). For open-channel flows, the assumption that Fr
= 1 when antidunes exist clearly permits flow depth to be estimated to the correct

Encyclopedia of Geomorphology
A symmetrical fluvial BEDFORM produced by near- critical flows, forming in
broad shallow channels, and comparable to a sand dune. However, antidunes
are more temporary and are less com- mon than dunes. Antidune formation
requires a ...

Fluvial Processes in Geomorphology
The antidune is a bed wave which accompanies surface waves. The latter move
upstream for short distances in trains, then collapse, reform, and migrate
upstream, only to break up again. Antidunes also move progressively upstream
and are ...

The solutions in Fig. 4 and consideration of the genesis of turbulent hydraulic
jumps also suggest that the flow depth should be the same order as the antidune
heights. DISCUSSION The sequence of events observed with waves breaking on
