Description	Unsaturated hydraulic conductivity K(h) is key characteristic for numerical modeling of water flow and solute transport in the vadose zone. Tension infiltrometer is advantageous tool to conduct the measurement of unsaturated hydraulic conductivity in the field under near saturated conditions. Manually operated minidisk infiltrometers are often used for performing infiltration experiments, but their disadvantage is that permanent attendance is needed during experiments. Therefore automatization of the tension infiltrometer is desirable. Multidisk infiltrometer has been tested on four experimental locations. Two sites were situated at arable land (Nucice and Kopaninsky stream) and two located in headwater catchments Bohemian Forest and Jizera Mountains). Soils at experimental sites were classified as Dystric Cambisols, Cryptopodzols and Podzols (empirical van Genuchten parameters α and n ranged from 0.020 to 0.048 cm-1 and from 1.11 to 1.55 respectively). The infiltration experiments have confirmed, that the device is suitable and efficient tool for determination of unsaturated hydraulic conductivity in broad range of soils.
