Development of River Meander Model

Development of River Meander Model DOI:  https://doi.org/10.30564/jgr.v3i1.1845 Abstract In the studies of open-channel flow with suspended sediments, used a constant of Von Karman κ in a model for velocity profile. The augmentation parameters have been added by various researchers in more recent development of the boundary-layer theory of meander development. In this research new parameters will be included because of the existence of the turbulent flow region in meandering channels because of boundary-layer theory. Keywords:  Meander, Flow, Model, Boundary layer, Sediment

Empirical Studies in Alluvial Streams

Empirical Studies in Alluvial Streams DOI:  https://doi.org/10.30564/jgr.v3i1.1668 Abstract Meander flow takes place in one single channel which oscillates more or less regularly with amplitudes that tend to increase with time. Meanders are found in beds of fine sediments with gentle slopes. In this study, effort will be made to investigate meanders’ turbulent boundary layer and to improve the present knowledge about the river meandering phenomena. It is assumed that the development of the perturbations which develop into meanders or braids, is longer than the width of the channel. Interaction be tween the flow and mobile boundaries produces channel patterns which are classified as meandering or braided. It is therefore long compared with the ripples or dunes which cover the bed of such a channel and whose wave length is shorter than the width of the channel. The variation of resistance to flow and rate of transport of bed material with velocity are discussed briefly and taken into...
