Channel process studies at great Siberian rivers

Abstract

The article deals with general conditions of the river channels formation at Siberia, reveals some spatial regularities of various types of channels and traces their relation with factors controlling the channel deformations character. On this basis the Siberian territory has been subdivided according to degree of geological and geomorphological control of channels (regions of free and limited development of channel deformations have been identified) as well as according to the type of channel-forming discharge. Regularities of development of me-andering and braided channels, prerequisites of many channel formation at floodplains etc. have been revealed depending on different factors combinations.

The special features of the Siberian rivers development show the necessity of working out regional schemes of river channels regulation considering requirements of various branches of economy.
