The aim of the work is to investigate the accuracy of the DEM of nearshore areas using UAV material. One of the important issues in hydrological flood modelling is the high accuracy of the DEM. In the case of a complex relief type, which is associated with meandering riverbeds, it is proposed to use UAV surveys to create a DEM.
Channel processes are the most dynamic exogenous geomorphological processes. This scientific field of research has many complex scientific problems and has long been developed in Ukraine and around the world in various fields of science, namely geomorphology, hydrology and technical sciences. The channel process is in constant and close connection with the geological, geomorphological, climatic and soil conditions of the territory.
Aim. The aim of the work is to research the method of studying horizontal displacements in the channel of the Dniester river from town Galich to town Zalishchiki using topographic maps of different periods, special maps, and space images. Such an integrated approach of using various data for receiving input information about the river bed together with processing in ArcGIS made it possible to monitor the displacements of the channel, and to determine displacement values over a significant period of time.
