ABSTRACT
Changes in hydrodynamic conditions are of great importance in the relief formation of coasts and bottom in the areas of variable backwater of reservoirs: irregular decrease in the rate of discharge currents, and concurrent fluctuating water levels, as well as gradua growth of wind and wave loads with the increasing width and depth of the water area. It is directly related to the peculiarities of morphology and dynamics of bottom topography forms, and indirectly – to the variety of types of banks. The paper presents analysis of the dynamics of bottom ridges in the variable backwater of the Bratsk reservoir at the Angara River as well as the main types of banks specific to this area.

Keywords:variable backwater area, hydrodynamic conditions, bottom-living forms of relief, exogenous geological processes, types of banks
