Abstract: In this study, the mechanisms of formation and distribution characteristics of exodynamic processes developing in the Nakhchivanchay basin over the territory were systematically investigated based on modern scientific methods. During the study, the geological structure, lithological composition, tectonic features, and geomorphological conditions of the territory were taken as the main objects of analysis. The intensity and spatial differentiation of the processes formed as a result of the interaction of these factors were widely evaluated. Within the framework of the study, the morphometric indicators of the territory were determined by applying digital relief models, satellite data and geographic information systems technologies. In particular, the degree of inclination of the slopes, exposure characteristics and the level of fragmentation of the relief were analyzed in detail. In addition, the distribution of structural linearities and tectonic faults was assessed using cartographic methods and sensitive areas in terms of risk were identified. The conducted analyses showed that erosion, landslides, denudation, and floods are observed more intensively mainly on steep slopes, in areas where weakly resistant rocks are distributed and in tectonically active zones. At the same time, climatic and hydrological factors, especially the amount of precipitation and the formation of surface runoff, play an important role in strengthening these processes. In addition, it was determined that anthropogenic impacts are also significant. Agricultural activity, improper land use and construction work lead to disruption of the natural balance in some areas and acceleration of processes. In particular, the weakening of vegetation cover further increases the risk of erosion.
