Description
Summary:Saturated hydraulic conductivity is one of the most essential soil parameters, influencing surface runoff and water erosion formation. Both field and laboratory methods of measurement of this property are time or cost-consuming. On the other hand, empirical methods are very easy, quick and costless. The aim of the work was to compare 15 pedotransfer models and determination of their usefulness for assessment of saturated hydraulic conductivity for highly eroded loess soil. The mean values obtained by use of the analyzed functions highly fluctuated between 2.00·10−3 and 4.05·100 m·day−1. The results of calculations were compared within them and with the values obtained by the field method. The function that was the best comparable with the field method were the ones proposed by Kazeny-Carman, based on void ratio and specific area, and by Zauuerbrej, based on total porosity and effective diameter d20. In turn, the functions that completely differed with the field method were the ones proposed by Seelheim, based on effective diameter d50 and by Furnival and Wilson, based on bulk density, organic matter, clay and silt content. The obtained results are very important for analysis among others water erosion on loess soil.
