Low Domain

Unsaturated conductivity for liquid water flow will be calculated from the liquid water present in pores that are smaller than what is given from the total liquid water without any account for the ice in the soil.

Low + High Domain

The conductivity will be calculated based on a two-domain approach where some liquid water is in smaller pores than those occupied by the ice (Low-domain) and some other are in larger pores (High-domain).
