Talk:Permeability (soil science)

I think that this article should be merged along with the other two to a new article titled either infiltration rate or saturated hydraulic conductivity. Comments? H2O 13:31, 21 April 2006 (UTC)


 * A merge will work - with relevant sections for each application.


 * Infiltration rate is not saturated hydraulic conductivity. Infiltration implies small head (sprinkler infiltration rate, for instance). Permeability seems more appropriate as an umbrella for this information than conductivity er hydraulic conductivity.


 * There is some incorrect information on the soils application. Soil internal permeability and surface infiltration are treated as if the same in the permeability (soil science) article when the fact is that they are treated as separate parameters in soil characterization.


 * Would this not also be the opportunity to merge with permeability (geology). My preference would be to merge all four articles into a new permeability (geosciences) article, since all three (geology, hydrology, and soil science) are.  -- Paleorthid 16:14, 21 April 2006 (UTC)


 * Paleorthid, please make any corrections and or mergers you feel that are necessary. I was really trying to create an article on infiltration rate, but I don't mind if it is a subsection of a larger article.  H2O 23:18, 21 April 2006 (UTC)

Here is a reference that might be helpful, Soil and Water Conservation Engineering, 2005, 5th ed. ISBN 1401897495. I have the 3rd ed., by Schwab, et. al., 1981. On p. 49 (ch. 3) of my copy, "The term infiltration rate refers specifically to entry of water into the soil surface. Infiltration rate has the dimensions of volume per unit of time per unit of area.  These units reduce to depth per unit time.  Infiltration should not be confused with hydraulic conductivity nor with soil capillary conductivity.  Infiltration is the sole source of soil moisture to sustain the growth of vegetation and of the ground water supply of wells, springs, and streams." Guess I should have paid better attention in class!

The section goes on to discuss the factors influencing the rate of infiltration such as the soil cover, soil moisture, surface sealing, slope, soil additives, a formula for an infiltration curve, etc. H2O 20:30, 22 April 2006 (UTC)

I suggest to pick the good references out, and delete (or redirect) this to the existing Permeability (geology), or Permeability (geosciences) (yes, absolutely I support that suggestion). Mwtoews 16:22, 25 July 2006 (UTC)

Merged
I've merged this to Permeability (geology), but copied the text into Infiltration (hydrology), since it was more appropriate there. Argyriou 23:05, 8 August 2006 (UTC)


 * Oops. Moved redirect to Permeability (fluid), since that's what Permeability (geology) redirects to. Argyriou 23:07, 8 August 2006 (UTC)
