Fluid Flow: Antidunes
Antidunes 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.

While reviewing the referer logs for this weblog, I came across a MSN search for "antidune experiments" that generated two hits. I went to the search to see if there were any new data on antidunes.

Fluid Flow was the third listing. The second listing was the antidune reference page that I maintain. The top listing pointed to a DOE site that I have never heard about. More importantly the title described antidune structures exactly. So off I went, hoping that someone had made similar observations to mine.

What I found, however, was a citation for an abstract that I wrote in 1987. I didn't know that it was available on the web.

The abstract is important because it provides a model of how antidunes produce internal sedimentary structures. 17 years later, it still works, though I think upstream dipping strata are more common than I did in 1987.
