We examine some aspects relating to direct influence of vegetation on channel processes of morphologically homogeneous sections of rivers. Changes in vegetation pattern can lead to changes not only in the channel breadth but also of its type. Timber jams constitute a characteristic manifestation of the vegetation influence on the channel morphology and channel processes of small rivers in forest regions. It is shown that changes in hydrological conditions of rivers, coupled with a decline in mobility of the channel’s relief features, resulting from the channel regulation by large reservoirs are favorable to the growth of vegetation. Growth of vegetation, in turn, has influence on the character of transformation of the channel’s plan form.
