Objectively identifying spatial variability in bankfull stage
The bankfull flow concept has occupied a prominent role in geomorphological theory about process dynamics in alluvial meandering river systems for decades. As the flow that defines the transition between channel and floodplain and marks the level of incipient flooding, bankfull flow represents an …

Geomorphic Equations and Methods for Natural Channel Design
… reaches indicates that the return period of bankfull flow (annual maximum series), ranges from 1.01 to 1.7 years, with an average of 1.2 years. This is significantly lower than the 2-year flow commonly used by engineers in naturalistic river designs. An equation is developed that predicts the …

Downstream change in channel hydraulics along the River Severn, UK
… sites along the Severn, under 3 flow conditions (low, medium and high) defined by exceedence frequencies. A flow event, occurring between 15-24 February 1989, was simulated by the 1-D hydraulic model, MIKE11. The simulated reach consists of cross sections spaced at 1 km intervals …

Stream Habitat Characterized by Stage -Specific Flows and Three-Dimensional Geomorphological Complexity: Development of Ecological Criteria for Stream Restoration Design
… geomorphological complexity, and associated flow structures at low- and high-flow stages. In this two-tier classification scheme, the term fluvial habitat unit was used because fluvial refers to both form and flow. At low-flow stages nine habitat units were identified; they included …

The Form and Function of Headwater Streams Based on Field and Modeling Investigations in the southern Appalachian Mountains
… to erode their beds during regularly recurring flows as well as the recurrence interval of bankfull flows. Field survey results demonstrate that the channels are dominantly alluvial and vary greatly between and within channels in their overall longitudinal form, channel slope values, and grain …

Probabilistic source-to-sink analysis of the provenance of the California paleoriver: implications for the early Eocene paleogeography of western North America
… area. We demonstrate that average discharge is a flow of variable magnitude and recurrence interval in rivers with different hydrology, and that at higher magnitudes of discharge, especially 99th percentile discharge and higher, the discharge yields and recurrence intervals of flow events of given …

Sedimentology of multistorey fluvial sandstones of the Mississippian Cypress Formation, Illinois Basin, USA
… In addition, a discrepancy between estimates of bankfull flow depths derived from mean dune cross-set thickness and core-derived channel fill thickness was identified, suggesting that most dune cross-sets in the Western Belt do not scale to predicted flow depths and that the thickest dune …

Predicting suspended sediment in Illinois rivers using dimensionless rating curves
… rating curve analysis. Field measurements of bankfull height at each site were taken and cross-referenced with the USGS discharge to determine bankfull discharge. The suspended sediment concentration at that bankfull discharge is referred to as the bankfull suspended sediment concentration. …
