Assessment of soil erosion hazard and its mapping using GIS technologies

The article presents a method for creating territory erosion hazard integrated map using RUSLE integral model, Earth remote sensing data and GIS technologies. studies carried out on this topic are presented, the analysis of which has shown more active use indicators water-erosion processes in foreign scientific works. Urgency updating methodology studying been substantiated. Theoretical foundations application models soil given, model is substantiated, optimal way proposed. research developed, consisting primary processing data, calculation factors development creation map. Based aerial photography materials, point cloud, digital elevation an orthomosaic study area were created. results geoinformation included erodibility factor topographic factor, presented. indicator watererosion hazard, complex Main patterns geographical distribution values revealed, devised assessed. It was found that schematic reflects general pattern water processes: they places where dissected relief spread. Influence shown: territories occupied by sod-podzolic loamy soils qualitatively differs from lands sandy loam widespread. Patterns different parts developed linear forms relief, formed temporary streams, described. proposed can be used to assess territory. need take into account larger number refine assessment existing ones concluded.
