WebOct 1, 2024 · The high flow capacity of the incised channel was reflected in high shear forces exerted on the channel boundary and in high competence of the stream, with a 2-year flood entraining cobbles and a 20-year flood able to mobilize cobbles and small boulders. This high competence of flood flows has resulted in outwashing of gravelly alluvium and ... Webon the channel bed. Deep, highly incised channels are typically associated with fine-grained channel bed and bank materials, and large-scale headcuts or knickpoints. Incision depth is recorded as none, 0-1 m, 1-2 m, or >2 m. o Bedrock Outcrops/Exposures (% of channel bed): Describes the presence of bedrock within the channel bed and/or banks.

WebMay 1, 2024 · In incising channels, however, bankfull discharge (i.e. the flow filling the channel to the top of the banks; Williams, 1978) no longer represents channel forming flow because increasingly large flows are associated with increasingly large bed shear stress ( Florsheim et al., 2013 ).
