WebPacker Permeability Testing in Boreholes in Rock The in situ testing techniques described in Section 12.8.1 are commonly used as part of site investigations in soil and can also be applied to boreholes in rock. However, in practice, a different approach is often taken for permeability testing in boreholes drilled through rock strata. WebPlant roots can change the soil water retention curve (SWRC) and saturated permeability (k(sat)) of vegetated soils. However, there is no model that could capture both the effects of root growth and root decay on these soil hydraulic properties simultaneously.
