title = "Secondary currents and flow variability in straight open channels: Implications for stream restoration projects",
abstract = "Laboratory experiments have been carried out in order to study secondary circulation and flow variability in straight open channel flows. The experiments represent the initial stage in the restoration of a channelized urban stream in northeastern Illinois. Mean flow and turbulence measurements provide the basis for the study of the effects of projected pool-riffle structures with the objective of increasing variability in the flow patterns. The results allowed for the quantification of hydrodynamic variability in terms of secondary velocities (5% of mean flow velocity), cores of high streamwise velocities (10% higher than surrounding flow) and bed shear stress (20% oscillation with respect to cross sectional averaged value). All these patterns are consistent with results reported in the literature, and provide experimental verification of a simplified model of secondary circulation.",
