Morphological patterns of mountain headwater channels of the Outer Western Carpathians.
Original language description
Channel-reach morphology classification by Montgomery and Buffington (1997) was applied in the Western Carpathian streams predisposited by flysch geological structures. This classification was extended by two intermediate morphologies: bedrock-cascades and steprapids: Bedrock-cascades were distinguished by occurrence of bedrock and lower sediment supply from cascades. Step-rapids are different from step-pools due to lacks of developed pools and probably higher sediment supply. General trends as wideningof bankfull channels with increase of basin area were observed in local channels. By contrast, bankfull depth was recognized as an independent variable due to its low variety. Downstream coarsening was significant for slope-channel coupled reaches only.Some certain ratio of channel width and d90 predicted interlocking of boulder steps and origin of well-developed step-pool morphology, which supported jamming theory introduced by Church and Zimmermann (2007).
