Bed forms in alluvial channels
Journal of Fluid Mechanics, 1966A solution is offered for the relative phase relationship of bed, depth and surface waves observed in alluvial channels, and is found to be in good agreement with observation in laboratory flumes. The solution does not depend on an assumption of a phase lag between the velocity and sediment movement. The emphasis of the paper is on the mechanics of bed-

Experimental Investigation of Form of Bed-Roughness
Journal of the Hydraulics Division, 1970Experimental observations regarding mean velocity distribution, angle of flow, static pressure distribution and longitudinal turbulence intensity are all made along a typical wooden wave in the domain of ripples and dunes of river flow. The wave was produced in a low-turbulence wind tunnel and the measurements were made by hot-wire anemometry in an air

THE NATURE AND ORIGIN OF BED‐FORM HIERARCHIES
Sedimentology, 1968SUMMARYThe bed forms generated by liquid flows over loose‐grain boundaries assume only two orientations relative to flow, being either transverse or longitudinal, but range enormously in physical scale. Two types of bed form, current ripples and parting lineations, take a characteristic length (2) which is independent of boundary conditions as ...

A method to evaluate length and height of bed forms in vegetated beds
2012In order to modelling the interaction among plants, flow field and sediment transport in vegetated rivers, some simplifications are often necessary. Accordingly, bed forms in vegetated rivers are often not considered, neither in the determination of resistance, nor in the definition of sediment entrainment.
