Automated set-up designed to measure hydraulic parameters in heterogeneous soil close to saturation

Original language description

Experiments were conducted on large undisturbed soil samples to measure hydraulic conductivity function directly. As a next stage, an enhanced set-up with fully automated data acquisition was developed to allow long infiltration-outflow experiments undervariable saturated conditions. To control the upper boundary condition the tension infiltration disk is used. Continuous weighing of the sample during the experiment monitors changes in the soil water content. For undisturbed soil sample of coarse sandyloam, a sequence of experimental runs was performed, each represented by a constant suction pressure head applied to the soil surface. All experimental runs show several noticeable stages, the bulk soil water content changes during those stages are presented here. Automation of the experimental set-up allowed the extension of the experiment duration and improved the accuracy of the data. Because of the long experiment duration, remarkable phenomenons were observed.
