Fig. 7. The hydraulic conductivity function (HCF), K(), predicted according to (a) Eq. [A6] and (b) Eq. [A4] (curves) and measured values (solid symbols) for Columbia sandy loam, Touchet silt loam, and an unconsolidated sand at different values of compacted bulk density, _c. The dashed lines represent the HCFs at the initial bulk density.
