Morphological features of a small river channel (with special reference to the Yug River) are discussed together with channel deformations pattern controlled by physicalgeographic and geological-geomorphic conditions. Channel configuration and bed forms are shown to be connected with conditions during the channel-forming discharges. Bedload volume increases downstreams which changes correlation between channel-forming discharges and related channel configurations and bed forms. In the upper reaches of the river both incised and free meanders are characterised with similar morphology, which suggests their common origin and connection with present-day hydrology. Downst-reams the two types of meanders are not related which reflects different conditions of the channel formation, the river discharge being then essentially different from the present one.
