Fig. 6. Hydraulic conductivity as a function of the matric potential head of intact and cut aggregate samples of Soil Block 5B as well as of the skin of intact samples. The symbols represent hydraulic conductivity values evaluated from data of the imbibition experiments according to Dirksen (1975) using Eq. [2] through [5] and White and Perroux (1989) using Eq. [10]. The VGM-type relative hydraulic conductivity functions were evaluated using desorption water retention and matched at Dirksen-evaluated values.
