Opis:: Monitoring of water erosion and runoff processes was conducted in an agricultural micro loess catchment of 1,05 ha area located in the Lublin Upland. Results of the studies shoved that, over 250 m³ of runoff and about 11 t of soil was removed from the catchment during two and half year. On the basis of results a relationship between temporal rainfall intensity and runoff rate was developed in the form of the exponential function Sp = 1E - 05e 102,64x. The relationship between run-off and soil losses was described by logarithmic equation Eg = 0,4703Ln(x)-0,5361.

Opis:: The work contains results of observations on the relationship between precipitation and surface runoff and slopewash on the surface plots in UMCS Science Station in Guciów. Observations come from a period of 6 years (2000-2006). Tests were conducted on three plots with typical use of the area. Two plots, with meadow and fallow land, were on the south slope and inclination of 3-5°. The third plot was established in the forest, whose slope was inclined at an angle of 13-18° and east display. Cover of soil in the station area, are eroded podsol soil, with silty sand in the arable layer. Obtained results of the observations were included in the form of regression equations describing the relationship between rainfall during the summer and surface runoff, runoff and slopewash of soil's, rainfall erosivity factor and slopewash.

Opis:: The study on soil wash was conducted on the experimental slope within the Scientific-Research Station of the Institute of Geography and Spatial Organization (Polish Academy of Sciences) in Szymbark in years 1990-96. Five experimental plots installed on the slope were 2m wide, had lengths of 2, 4, 8, 16, and 32m and were under black fallow. Measurements of overland flow and soil wash reveled relationships between the processes and lengths of the plots and sums and intensity of rainfall events. The volume of the surface flow increased with increasing length of the plots, from 3352 dm³ (2m) do 12153 dm³ (32m), but on the other hand this was accompanied by decrease in the flow index. The index value was highest on the shortest plot (2 m) - almost 5 times greater than on the 32m-long plot. The observed relationship is typical for the river catchments: the smaller the catchment, the higher the flow index is (pertaining to 1 km² of the area). The soil wash occurred to be more differentiated with respect to the length of the plots (from 131,6kg to 1166,4kg). The relationship between maximum intensity of rain and soil wash on all plots has a character of polynomial equations of the second degree, described by negative correlation coefficients. As the plot's length increases, the relationship is stronger. During rainfall events of a very high intensity, over 1,5 mm min⁻¹ (high kinetic energy), the soil wash is limited by aggregating soil particles due to action of the rain droplets. Agrotechnical treatments significantly influence the process of soil relocation (weeding, ploughing). Observed soil wash directly following such treatments was much more intensive in comparison with conditions of slightly compressed soil.
