This paper presents a new method to predict channel bed topography in meandering channels in a range of resonance of free and forced bars, in which previous models have not successfully predicted the finite bar topographies. Depth integrated version of three dimensional Reynolds equation is used to calculate the mutual effect of bed and channel geometry, while the intensity of secondary flow is calculated from the first order differential equation of the momentum equation in transverse… Expand
Hierarchy of models for meandering rivers and related morphodynamic processes
We review the importance of the physical mechanisms involved in river meandering by comparing some existing linear models and extensions thereof. Such models are hierarchically derived from a commonExpand
Free bars in rivers
In the paper we review some recent work on the mechanics of formation and development of river bars. The emphasis is placed on the instability process which leads to the spontaneous development ofExpand
Response of channel dynamics to recent meander neck cut-off in a lowland meandering river with artificial training history: the Morava River, Czech Republic
ABSTRACT One-decade-long observations of post-cut-off channel development and oxbow lake formation are presented to offer insight into the morphological response of the Morava River to neck cut-off.Expand


Flow and Bed Profile in Meandering Sand-Silt Rivers
Mathematical models for defining three-dimensional flow and bed topography in sinuous channels with suspendable bed material are presented. It is shown theoretically that the secondary flow inExpand
Secondary Flow in Mildly Sinuous Channel
Most analytical models of the flow and bed topography in sinuous channels include the assumption that the secondary flow is locally adapted to channel curvature. Recently, Kitanidis and KennedyExpand
A unified bar–bend theory of river meanders
A two-dimensional model of flow and bed topography in sinuous channels with erodible boundaries is developed and applied in order to investigate the mechanism of meander initiation. By reexaminingExpand
