	A system of slope erosion control, consisting of horizontal terraces equipped with drainage ditches filled with sand, was developed in Olszanka, Poland. This system relies on combining two types of erosion control on steep slopes: limiting soil transformations and increasing the infiltration of surface water into the subsoil. The new soil erosion control system is located on a fruit farm in Olszanka. We assessed the functionality and efficiency of the system by calculating the eventual increase in infiltration gained via the drainage ditches. This assessment was performed using the numerical model FEFLOW 5.2. The calculations covered a 74-d period (summer 2003) and relate to two groups of terraces located on different parts of the slope. The values and directions of groundwater flux and velocity resulting from the calculations were analyzed. We observed a clear increase in infiltration for terraces equipped with sand-filled drainage ditches under real climatic conditions: 11.69 and 13.6% increases for the base and upper parts of the slope, respectively. The results were empirically verified by comparing measured in situ and calculated values of soil water content; values of R(2) = 0.702 to 0.799 (P = 0,05) for four points on two terraces were determined.
