By definition, hydraulic conductivity is the ratio of volume flux to hydraulic gradient … WebA soil mass also consists of a number of interconnected voids that act as capillary tubes of varying diameter. And because of the capillary effect water in the soil rises above the water table in these voids up to some height. The water present in the soil pores below the water table is in compression and pore water pressure is positive.

WebGradation is an important factor for bearing capacity and for the compaction and is determined from the grain-size distribution curve.
