THE ESTIMATION OF DIRECT RUNOFF USING THE CURVE NUMBER METHOD (SCS CN) IN THE VIŠTUCKÝ CREEK CATCHMENT. In the article the curve number method (SCS CN) is tested for estimation of runoff from small river basins in our conditions. The curve number method is an empirical method for predicting direct runoff from rainfall excess and it is used in many rainfall-runoff and erosion models. The basic input to the method is rainfall depth which is transformed to the depth of direct runoff using runoff curve numbers. The sensitivity of runoff curve numbers on antecedent moisture conditions was examined. The empirical data was also used to define the impact of the ? constant in the SCS CN method, which is determining the size of the initial rainfall loss, on the depth of direct runoff.
