The aim of the paper is to identify the effect and clarify the share of selected basin parameters (risk factors), which contribute to the increased effect of storm rainfall and eventually flash floods. It contains analysis of morphometric and geometrical characteristics of small basins struck by flash floods. The following characteristics describing the relief morphometry were evaluated: mean sea level altitude, maximum sea level altitude, minimum sea level altitude, the difference between sea level altitudes, maximum inclination and mean inclination in the direction of gradient line. Surface, shape of basin and length of water dividing line were the geometrical basin characteristics considered. Several characteristics of the river network, which are closely related not only to the basin shape, but which jointly affect the magnitude and form of floods are pointed to. Basins with occurrence of flash floods and the selected basin parameters contributing to their origin are identified through application of the existing digital network of small basins in Slovakia and the database of their physical characteristics. A set of 77 small basins with occurrence of flash floods in the years 1997-2002 is evaluated.
