Abstract (in english)
   This study is focused on the comparision of soil hydraulic properties that is affected by erosion processes. Haplic Chernozem reminded at the flat upper part of the area. Regosol were formed at steep parts of valley. Colluvial Chernozem and Colluvial soil were formed at the bottom parts of the valley and the bottom part of the studied field. The undisturbed soil samples (3200 cm3) were also taken at three sampling sites and ponding infiltration experiment were performed in the laboratory. Cumulative inflow and outflow, and preasure heads at depths of 6.5, 11 and 15.5 cm were measured. Numerical inversion of measured data using HYDRUS-1D was performed to obtain parameters of van Genuchten hydraulic fuction.
