GEODYNAMIC CONDITIONS OF NATURAL HAZARDS WITHIN MIDDLE DNIEPER REGION (BASED ON STRUCTURAL-MORPHOMETRIC ANALYSIS)

Ukraine is characterized by active natural hazards processes within different structural and tectonic and landscape-climatic zones. Within the Middle Dnieper Region, the gravitational processes are most widespread. The determining factors of these processes are lithologic and stratigraphic conditions; hydrogeological regime; structural and textural features of rocks; geomorphology of slopes. The second category of factors includes dynamic processes, erosion, weathering, tectonic regime of the area, and anthropogenic impacts. The basis of studies is the structural-morphometric method. Structural morphometry, aimed at investigation of various tectonic structures and vertical movements of the earth’s crust, is the tool to identify the genetic relation between geomorphological and tectonic processes. As a result of the structural-morphometric studies, a number of morphometric models and maps have been built. The most informative from the natural hazards forecasting point of view are the maps of residual relief. On the basis of comprehensive geological-geomorphologic studies, the influence of tectonic movements and exogenous geological factors on the development of natural hazards within the Middle Dnieper Region has been determined. According to the data of structural-morphometric analysis, local structures have been allocated, which are characterized by the formation and activation of hazardous geological processes. They are located mostly at the right steep slope of Dnieper River. Created models are the basis for forecasting of hazardous geological processes.
