Abstract

The AA .evaluated a large dataset of channel-reaches coming out from flysch midmountains. Two new channel-reach morphologies were distinguished with respect to their differences in the ratio of sediment supply to transport capacity : bedrock-cascades and step-rapids. The chaining of channel-reach morphologies by gradient criteria and the parameters of channel gradient and bankfull width related to the basin area show similar trends, when compared to other recent studies. By contrast, bankfull depth indicates its independence on increasing basin area. Significant downstream coarsening of bed material occurs only in alluvial stepped-bed morphologies (cascades, step-pools and step-rapids) mainly due to strong slope–channel coupling processes. An amount of large woody debris is closely related to the activity of strict local forest management in evaluated channels, as a significant decrease in large woody debris pieces is observed with increasing basin area
