Comparison of runoff and soil loss generated on two plot sizes during rainfall simulation experiments

Popis výsledku v původním jazyce

Water erosion is a natural process of soil surface disturbance caused by rainfall and surface runoff and consequent transport of sediment and nutrients. Synthetic rainfall-runoff and erosion events and mathematical models are still actual and useful methods for analysing processes involved in surface runoff formation. Simulators with watered area of 1 m2 are often used due to the technical, financial and human resources limitations. Disadvantage of such small-scale simulators is that concentrated runoffseldom developes there which makes observations difficult to upscale. We present a set of experiments which were focused on the effect of plot size on observed surface runoff, soil loss and particle size distribution of suspended soils and on formationof preferential pathways. The contribution presents the results of two years of measuring with the rainfall simulator. Presented experiments were focused especially on the comparison of runoff process dynamics, total runoff volume and soi
