https://doi.org/10.4467/20833113PG.16.019.6081Soil erosion by water is one of the most important morphogenetic processes taking place within the lowland geoecosystems in Poland. Therefore, it is relevant to recognise its nature, course, conditions and dynamics. This article presents some lithological conditions of water soil erosion on a testing plot within the Chwalimski Potok catchment in the Drawskie Lakeland. The conducted measurements of soil particle size distribution, soil moisture and compaction, shear strength and degree, as well as infiltration rate constitute the basis of the analysis and all relevant calculations. It was shown that topsoil (slightly loamy sands) with increased humidity at the surface is most susceptible to the process of soil erosion by water. Some methods to prevent adverse degradation processes were suggested in the article.

https://doi.org/10.4467/20833113PG.14.018.2700Stationary research upon soil erosion has been conducted in the Chwalimski Potok catchment since 2012 as a continuation of research started in 1994. In 2013 conducted two field experiments were conducted in order to evaluate the impact of high intensity rainfall on soil surface. The first experiment consisted of 5 and the second of 4 rainfall simulations. The rainfall was created by using a purpose-built rain simulator, consisting of 3 and 6 sprinklers placed around the testing plot. The paper focuses on the characterization of the course of these experiments. The achieved results compared with the results from the hydrological years 2012 and 2013 show that slope wash considerably increases during rainfall of high intensity and high amount.
