The aim of the thesis is a calculation of erosion flushes of the catchment of Malče - Budský stream. The surveyed stream flows through the Soběnov highland area of Besednice, Malče and Soběnov municipalities. The thesis also describes the water catchment model from pedological, geological and climatological perspective. The main objective is to compare different calculation methods of erosion flushes in the catchment. The comparison covers the Universal Soil Loss Equation by Wischmeier and Smith and the CN (Curve Number) Method, which is used for the total runoff and culminating flow calculation. A modified Universal Soil Loss Equation by Williams and Berndt is used to determine the erosion flushes. The results of both methods mentioned above are compared at the conclusion of the thesis.
