abstract
The knowledge of hydraulic conductivity in unsaturated zone K{h) has a great theoretical and practical importance for soil water balance. The existing measurement methods of that parameter are rather complicated and time-consuming, hence the still growing interest in alternative, calculation methods.
The article presents the results of laboratory tests of hydraulic conductivity of peat soil, by Wind's dried monoliths method and their comparison with calculated values obtained by Van Genuchten's formula. The authors present also the results of numerical calculation of the capillary rise in peat soil.
