High-Altitude Landscape Mesozones and Exodynamic Phenomena in Voronezh Model Region

Abstract

The aim of the research is to reveal the confinement of exodynamic phenomena in the Voronezh model region to high-altitude landscape mesosons of plains. Materials and methods. Source materials for analytical generalizations were field observations at semi-stationary ranges located in the Voronezh Don Region, expeditionary route observations and materials for interpretation of space images. Results and discussion. Field materials, agricultural enterprise funds, semi-stationary observations and remote sensing results show that exodynamic phenomena in the Voronezh model region are very closely related to the altitude and landscape differentiation of the plain relief. For example, water and wind erosion is widespread throughout the region. However, it is most often found within the boundaries of elevated-denudation and vertex-water-separated mesozoans in the Central Russian and Kalachskaya Uplands. In the Oka-Don Plain, wind erosion is observed in areas of high land tillage in the lowland-hydrogen mesozone in the upper reaches of the rivers Plavica, Bityug and Maly Ertil. The main exodynamic phenomena on the Central Russian Upland are water erosion and karst denudation, where the vertex-water separating mesozone (200-250 metres) has spread. Conclusions. Our numerous studies show that in the Voronezh model region there is a full list of exodynamic phenomena known in the administrative areas of the centre of the Russian Plain – ravine and water erosion, landslides, mudslides, landslides, karst denudation, plain mudflows, rockfalls.
