channel bed sediments, channel-reach morphology, macrogranulometric analysis, flysch nappe structure, Kobylská Stream, Vsetínské vrchy Mts.

The character of bed sediments reflects fluvial processes and the dynamics of material transport in fluvial (dis)continuum systems. The study focused on fluvial-geomorphological analysis of the Kobylská mountain stream based in flysch geologic structures in the Vsetínské vrchy Mts. The research was purposed with (i) fluvial-geomorphological mapping, (ii) recognize the sediment inputs and disconnectivities, (iii) identification of the channel-reach morphology, (iv) assessment of the grain-size parameters of the bed sediments and (v) evaluation of morphological parameters of channel in the longitudinal course of the Kobylská stream.
