Abstract

Various approaches are used by leading national and foreign researchers in determining the types of floodplain-channel complexes. The a key part of the study, is characterized by a variety of morphodynamic channel types, which is associated with a significant differentiation of natural factors forming valley geosystems within the Upper Stream of the Angara River. The main types of the Belaya River valley complexes have been identified. The length and nature of the distribution of morphodynamic channel types are revealed, their characteristics are given, the main types of floodplains are identified. The landscape characteristics of valley complexes within areas with different morphodynamic types are indicated. The dependence of the distribution of biogenesis on the factors of the formation of the relief of the valleys is revealed. Reliable medium-scale geomorphologic maps are compiled, reflecting the elements of the structure of the relief of valley complexes. The obtained data served as the basis for choosing points of comprehensive monitoring of the dynamics of the floodplain-channel complexes, including geomorphologic, hydrological, landscape directions. The feasibility of monitoring observations of the functioning of geosystems is due to the need to predict and prevent adverse effects caused by both natural manifestations of relief-forming processes, and initiated by human economic activities.
