Hi,

in groundwater hydrology, they call this term effective porosity.

Subject: Saturated soil water content


> Dear all,
> Rithcie (1985) soil water balance model requires saturated soil water
content as an input. I am not so sure but the saturated soil water content
is  equal to 100* (1- bulk density/particle density) or the total porosity.
I am wondering why Piara Singh in his online technical manual has calculated
it as (1- bulk density/particle density) * 85 or 85% of the total porosity.
Can someone explain this to me?
