Wykorzystanie eksperymentu terenowego w badaniach erozji wodnej gleb w zlewni Chwalimskiego Potoku (Pojezierze Drawskie, górna Parsęta)

Application of a field experiment in soil erosion research in the Chwalimski Potok catchment (Drawskie Lakeland, upper Parsęta River)Stationary 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.
