Lukianchuk K. Geoinformation modeling of development of erosion processes at local and regional levels.

Mapping of erosion processes is a precondition for geoinformation and mapping ensuring of rational land use. It makes it possible to locate the areas most vulnerable to erosive processes. Creation of soil erosion intensity map (erosion hazard) is the final product of erosion processes modeling using the Universal Soil Loss Equation and Revised Universal Soil Loss Equation (USLE / RUSLE). In the first chapter of the dissertation analyzes the previous developments in the field of erosion studies, as well as the methods of modeling erosion processes, identified a number of advantages of USLE / RUSLE. RUSLE was chosen to model erosion due to its simplicity, wide use, and manageable data requirements. This equation is combined with geographic information systems (GIS) and remote sensing methods for estimating and displaying averaged soil loss due to erosion. A high-resolution soil maps, together with rainfall data, a digital elevation models ASTER GDEM, ALOS World 3D-30m, SRTM, satellite images from LANDSAT 8, Sentinel-2 and statistical information about study area created the input information for erosion modelling in GIS environment.
