Channel activity of trunk rivers of the Amurskaya region in conditions of current economic management

Based on analyzing the recent research data on the Middle and Upper Amur, it is shown that the flow regulation of the Zeya and asymmetric engineering development of the Amur riversides modify the character, intensity and, in some places, the rearrangement direction of separate channel forms as well as of the channel as a whole. In the Amurskaya region, not only do the technogenic effects on the drainage area manifest themselves in the activity of low-order water streams, but they have influence on the operation of large rivers.
