Influence of Channel Reconfigurations on the Development of Confluence Nodes of Rivers

Using the confluence nodes of broad-floodplain rivers as an example, we examine the different variants of effects of channel deformations (channel meandering of the main river and its tributary, formation of forks, and shift of meander bars) upon their configuration and reconfiguration across time. We demonstrate the diversity of these effects even where the deformations themselves are of the same type. Problems of further investigations are formulated.
