Abstract

The AA. examine transport-storage relations during cycles of aggradation and degradation by augmenting observations of 3 events of channel aggradation and degradation in Cuneo Creek, a steep gravel-bed channel in northern California, with measurements from a series of flume runs modeling those events. Variations in channel morphology, and surface bed texture during runs that modeled the 3 cycles of aggradation and degradation were similar to those observed in Cuneo Creek and provide confidence in interpretations of the history of change : Cuneo Creek aggraded rapidly as it widened, shallowed, and braided, then degraded rapidly before armoring stabilized the channel. Such morphology-driven changes in transport capacity may explain the formation of flood terraces in proximal channels
