Abstract
The possibilities of using the data of remote sensing of the Earth for the establishment of hydropower potential on the rivers of the Ukrainian Carpathians are considered. Describes the main stages of work. The first is the collection of initial spatial and attributive information on the natural conditions, the orography and morphometry of the catchment, characteristics of runoff of rivers and protected areas within catchment areas. It is important to note that all work was done using data that is open access for scientific purposes. The use of geospatial information to establish the hydropower potential of the Ukrainian Carpathian Rivers is primarily the Shuttle Radar Topography Mission and the ASTER GDEM with a resolution of 30m per pixel for creating a digital elevation model (CMV) and a set of raster and vector layers morphometric and stock information on river basins. Remote sensing data, namely satellite imagery, such as satellites such as Landsat and Sentinel , were used to specify the lengths of the rivers, their leaks and the mouth sections, to update the state of the channels, and to identify the places of influence of water management activities. The second stage is the systematization and processing of data, the choice of methods and tools for geoinformation analysis. The calculations and analysis were carried out using a comprehensive software product that is also openly accessible, namely QGIS, Saga and GRASS.
The third stage is the visualization of the results obtained in the form of multi-layered river network maps, rivers catchment limits, the network of in-situ monitoring of the drainage of water (hydrological stations), maps of the average multi-year drainage water flow in the rivers of the basins of the Ukrainian Carpathians and maps of hydropower potential.
The algorithm of using remote sensing tools and geoinformation analysis for the establishment of hydroelectric potential of Mountain Rivers is developed.
