Assessment of erosion processes in the Svacenicky creek using physically-based erosion-3D model

Year, pages: 2018, 93 - 100

The aim of the study is to evaluate the influence of different management practices on erosion processes in the small catchment Svacenicky creek. The modelling was done using physically-based erosion model, Erosion-3D model. This distributed and event-based model represent the useful tool for predicting the amount of soil loss on agricultural land. Small catchment situated in the Myjava Hill Land in the western part of Slovakia with dominant water erosion threat, was chosen. Considering the time of concentration, the calculations were done for 100-year design rainfall with duration of 240 minutes and for one real measured extreme rainfall event. In order to assess the variability and intensity of erosion processes and runoff generation, five scenarios of soil initial moisture were created for four different scenarios of management practices, i.e. silage corn, grain corn, sugar beet and winter wheat. The results demonstrate the effect of changing agricultural management practices on the generation of runoff and the amount of soil loss. Based on them, it is possible to determine the best protective option of chosen management practices.
