The “constant head” permeameter determines K in coarser-textured soils from the volume of water (Q) that flows through the soil core over a period of time. WebApr 1, 2002 · Average hydraulic conductivities of unfrozen soils did not vary significantly with changes in soil-moisture content for most soil specimens. Hydraulic conductivities should increase with increased saturation (Freeze and Cherry, 1979).

"WebHydraulic conductivity K is a key parameter in hydrology that describes the ease at which ﬂ uid moves through a porous media (e.g., Freeze and Cherry, 1979; Deming, 2002). As part of Darcy’s Law, K is fundamental in quantifying groundwater ﬂ ow systems. K often exhibits a large range of variability (up to several orders " - Freeze and cherry 1979 hydraulic conductivity

WebFreeze and Cherry (1979, pg. 168) have stated that flow nets are an important concept of hydrology. They state, “The proper construction of flow nets i s one of the most powerful analytical tools used by the hydrologist to analyze groundwater flow.” In water table aquifers, groundwater behaves much like surface water in its patterns of flow.
