torrent, bed sediment, bedload transport, shear stress, unit discharge, stream power, Moravskoslezské Beskydy Mts.

Two methods were applied in small headwater streams in the region of the Moravskoslezké Beskydy Mts: flood competence method and marked particle displacement method. The first method consisted in the measurement of the diameters of the largest boulders (200-400 mm) that had deposited in fluvial accumulations as a consequence of a Q25 flood event (5/2010). Transport of marked particles (18-152 mm) was studied in the period between 11/2010 and 7/2011, during which several minor events occurred in local torrents and maximal observed discharge was equal to the bankfull stage (Q1-Q2). The latter method was also used in two selected gullies to evaluate the intensity of coarse sediment transport in initial channels.
