EXPERIMENTAL RESEARCH OF SOIL EROSION PROCESSES IN THE CZECH REPUBLIC

Original language description

Soil erosion by water is one of the main degradation processes on agricultural lands in the Czech Republic. The team on Department of Irrigation, Drainage and Landscape Engineering at the Czech Technical University in Prague have been involved in experimental measuring of surface runoff, soil erosion and soil transport processes for several decades. Based on the experiments, a physically based simulation model of runoff and soil erosion processes, SMODERP, was developed and USLE based models have been applied and calibrated. Experimental erosion plots were installed at Bykovice catchments (central Bohemia, Czech Republic) in 2009. The natural rainfall-runoff events and corresponding soil loss have been continuously measured there since 2010. Nowadays there are six experimental plots, three “Wischmeier’s” type (22 meters in length – vegetation, cultivated fallow and non-cultivated fallow), one plot with length of 4 meters (to be comparable with laboratory rainfall simulator data), and two plots of 8 meters (to compare with field rainfall simulator data). The outflow from each plot and precipitation intensity is automatically continuously measured during each natural rainfall event. The sediment samples are taken manually after the event. The soil concentration in outflow and total amount of transported soil is determined. Data from the experimental plots about rainfall intensity and duration, sediment fluxes and sediment concentration are presented in the paper. 20 rainstorms producing surface runoff have been recorded during four seasons. In total 1086 mm of rainfall has been measured during recorded erosion (surface runoff) effective storm events, what represent 40 % of average annual rainfall. Results shows different responses of surface with vegetation and cultivated fallow characterized by runoff coefficient and particularly by sediment yield.
