Have you looked into SIMULAT, sponsored by the German Research Society or
RETC by the Scientific Software Group in Washington, DC?
The software relates to hydraulic conductivity of the soil in both saturated
and unsaturated conditions?  Algorithms are given for conductivity as a
function of the soil water content. The parameters of the model are taken
from the van Genuchten or Brooks and Corey equations describing soil water
I believe there's some other related software available.

> Hello,
> For the evalution of office ventilation, we try to model the dynamic

> Are there any approaches to define 'equivalent' thermal conductivity
