Tom Clifton: Fluid Flow: AntidunesAntidunes are bedforms that form in fast, shallow flows. I have been fascinated by them since I was 5. They were even the topic of my dissertation, but that was mainly so I could continue playing in the sand.(Untitled)- June 13, 2002 Abstract The following abstract is from my dissertation, "Sedimentology of Antidune Flow: controls on sediment transport and stratification" Antidunes are bed configurations that form in sediment under fast, shallow flows. These wave-like features are highly unstable and contrast with more common bedforms, like ripples and dunes, by migrating upstream and changing dramatically in morphology over very short periods of time. Antidunes often amplify rapidly, deforming the flow above them until.http://radio.weblogs.com/0100021/categories/antidunes/2002/06/13.html#a251 |
