[edit] Saltation: 1-a geophysics process(+biology); 2-a concept

The orginal Saltation article was focussed on fluid transport in the field of Fluid dynamics-(stream flow). My original meeting with saltation was in sand-dune, and sand, (but see also loess), and later I saw the process used in analyzing river bottom movements of the "River load", the transport of particles downstream (which can end up: upstream in eddies, etc.)-

However, I still contend the "process" of saltation is a more important concept when used with time and the "rate-of-change" that occurs. To pick a geoligic time: "hundreds of years" or "thousands of years", is a statement that is 'unknowable'. I would assume with the speciation, and the overabundance of off-spring, -(the conclusion has to be): "Generations are Shortened!"--under some environmental conditions, I would err on the side, of more rapid 'Geologically-bsed' changes, as opposed to the extended: "thousands of years"; it may apply to some mammals, but I think the time frames, have to be shortened..[And....I do think this goes towards understanding the positions taken on the Punctuated equilibrium discussion-](I think some species come along so fast, one doesn't see them coming..) ... Just some thoughts--at... "part-of-1-year" after the original article was split. //--From the Arizona-Desert--Mmcannis 20:50, 19 November 2006 (UTC)

[edit] fluid dynamics

I added much of the original content on this page. FWIW, fluid dynamics is not the same as stream flow. The expression fluid dynamics refers to the dynamics of a fluid in an engineering sense, where air is as much a fluid as water.

Anyway, is it worth starting a page on transport of particles by fluids? —Preceding unsigned comment added by 142.207.115.25 (talk) 21:09, 25 February 2008 (UTC)
