Document title

Processes and forms of an unstable alluvial system with resistant, cohesive streambeds

Authors(s) and Affiliation(s)



As a response to channelization projects undertaken near the turn of the 20th century and in late 1960s, upstream reaches and tributaries of the Yalobusha River, Mississippi, have been rejuvenated by upstream-migrating knickpoints. Sediment and woody vegetation delivered to the channels by mass failure of sreambanks has been transported downstream to form a large sediment/debris plug where the downstream end of the channelized reach joins an unmodified sinuous reach. Classification within a model of channel evolution and analysis of thalweg elevations and channel slopes indicates that downstream reaches have equilibrated but that upstream reaches are actively degrading
