They must separate saturated and unsaturated soil from each other in their analyses, because the analysis of seepage of semi-saturated soils in a saturated state leads to wrong and unrealistic results. Such an error can be prevented by defining the permeability function in Geostudio software. Permeability changes linearly in the interval defined for this function and is considered constant outside this interval.

For this purpose, the Hydraulic Conductivity command must be selected from the Hydraulic Functions section. This will open the Conductivity Function window and users can apply their desired settings by editing the Function Number field
