Description	Temporary variable properties of periodically cultivated soils are one of the crucial factors that must be taken into account to understand flow processes on agriculture catchments. Soil structure is a property that is often considered as a static rather than dynamic. This could be a reasonable assumption for compacted subsoil, but not for the plough layer. The aim of the contribution is to examine the runoff dynamics along the inclined slope under different structural properties of the topsoil. We will present a numerical analysis of the effect of variable preferential domain ratio on subsurface runoff, the simulation results will be qualitatively compared to measured hydrographs at the catchment. We used a combination of physically based macroscopic models S1D and HYPO. In the S1D the dual permeability approach with two coupled Richards equations is used, the simultaneously operating HYPO code is based on a diffusion wave (Boussinesq eq.).
