抄録

The current study examines the evolution of alluvial meandering channels based on the laboratory experiments as well as field study. Experiments were conducted in erodible meandering channels to represent the natural scenario. Channel planform, as well as bed evolution, were analyzed. In the case of natural channels, time series satellite images were analyzed to understand the channel planform behaviour and bank erosion characteristics were analyzed through the real field data and photos. Results showed that the channel evolution characteristics vary from one alluvial meandering channel to another depending upon various channel parameters. It was found that low sinuosity channels and newly developed meander bends have higher tendency to migrate as well as undergo rapid channel adjustment. Bank protection counter-measures were effective in minimizing the bank erosion. At the same time, they tend to shift the point of erosion from one location to another.
