The relationship between saturated hydraulic conductivity and the soil erosion process are evident. However, the problem has not been so far sufficiently addressed in research, especially for typical Polish soils. Our paper presents the results of a modeling study on soil erosion losses and saturated hydraulic conductivity that was carried out in natural rainfall events on the 10 most typical farming soil types in Poland. The results show the relationship between saturated hydraulic conductivity and soil losses and saturated hydraulic conductivity jointly with sand texture group and soil losses. The conclusion is that the studies dealing with measuring saturated hydraulic conductivity may be applied to assess soil erosion losses.
