Abstract

Observations show that besides the magnitude, also the frequency and
duration of streamflow oscillations might be important for the river channel
formation. In addition, the river morphology appears influenced also by both size
and degree of uniformity of the sediment. Nevertheless, many morphodynamic
studies still represent the flow regime with a single value of the discharge, often
corresponding to the bankfull condition, and the sediment with its median grain
size. This work investigates the effects of streamflow variability and sediment
characteristics on channel width formation, analysing the evolution of
experimental streams with different sediments and discharge hydrographs. Results
show that the formative condition of the channel width is not the geometric
bankfull flow but a rather frequent peak flow.
