Talk:Sediment
From Wikipedia, the free encyclopedia
If we assume that r is the radius of the particle, the constant in the formula should be 2/9 (4.5) rather than 1/18, because this is true for the diameter being squared in the formula.
The Stokes forumla only applies to small particles (fine sand and smaller), in which the wake behind the settling particle is laminar. For large particles (coarse sand and gravel), an emperical equation to account for flow turbulence should be used over the Stokes formula (e.g., see Dietrich, 1982).
- The Settling article agrees with you, don't know why the difference. Settling through still fluid as opposed to a flowing fluid? hmm... no reference given. I'll change it and see if anyone disagrees. _Vsmith 00:45, 1 Feb 2005 (UTC)
Is sediment a synonym to alluvium? /Habj 15:08, 13 Jun 2005 (UTC)

[edit] Merge from Transportation (sediment) and Deposition (sediment)
These processes are very similar, and are already discussed in this article to some degree.
Also, this article doesn't have a clear distinction between transportation and deposition, as it is kind of mixed together in a mess.<Looks like this has been cleared up> It would also be nice to mention the basic [latin] diagenetic types: colluvium, fluvium, alluvium, and eluvium. +mwtoews 22:46, 3 November 2006 (UTC)
i think this article needs more information like the diffrent types of depostion and crap like that
I agree with the last section, that the article on deposits would be more complete if their were sections focusing on the diffrent types of deposits. I do not think it would be wise to merge this article on depositation with that on sediment. I feel sediment is more about the movement, and deposits are what happens when sediment is no longer moving. Also, I was looking at this artice to get a basis for coal deposits, and don't think anyone would call it coal sediment. 129.15.107.142 19:01, 21 February 2007 (UTC)
