Abstract:

The thesis represents the physical and theoretical aspects of soil erosion process influenced by the geomorphological factors and land use. Land use management and changes in land use certainly influence the water regime and the soil properties in the catchment. The aim of current study is to mitigate the harmful impact on soil.In this dissertation work different predictive models are studied in order to improve water management processes and design effective measures. This dissertation work analyses quantitatively to what extend the land use changes could influence a rainfall-runoff process. It is focused on short-term rainfall-runoff events with a short time step (less than 1 hour). These events are dangerous on small catchments as they cause local floods, or in combination with regional rainfall floods over larger areas. For simulation of these phenomena the KINFIL model and the different components of HEC-HMS software are applied.The current study is based in the theoretical assumptions, empirical data of experiments and on the experience and various studies in thematically related fields in other countries. The results of the studies are presented as publications in scientific journals and conferences.
