Catastrophic floods of 2013 and 2019 in the Amur River basin raise the problem of creating new regional conceptions for mitigation of inundation consequences. This article outlines the items of construction of a digital elevation model (DEM) of the rivers bed and floodplain of the Amur River basin for hydrodynamic modelling. The main data sources DEM construction and the process of updating the channel configuration using space imagery materials by the domestic spacecrafts “Resurs-P” and “Canopus-V” are described. The design of water level constructing technique and basic principles of the DEM operational correction are described. The results of numerical experiments on hydrodynamic modeling of the Amur River stretches using Stream 2D CUDA model are presented.
