Abstract
The handling of some soil hydraulic properties applying the nonuniformity of soil structure was considered to analyze the infiltration and drainage on the artificial depression areas in the urban park. On the sample in which soil texture and its particle density are equal, soil water retentivities and other properties in saturated ranges received clearly the effect of the bulk density distribution. Then we experimented the soil water retentivities and conductivities on the several bulk densities from the same soil origin, in this case, these rearrangements resulted in comprehensive estimation about both properties is available in unsaturated range (Ψe>Ψ).
However, some considerable problems were left, when the critical point Ψcr (almost equal to air entry potentialΨe, nec essary for estimating soil hydrological characteristics on the basis of those relations, was decided.
