Abstract: In the article, we attempt to characterize adverse natural phenomena in terms of intensity in various river valleys of the Nakhchivan river basin. In the Nakhchivan river basin, flood events attract significant attention due to the damage they cause to populated areas and the economic system, as well as the repetition of widespread hazardous natural processes. The villages of Bichenak, Kolani, Daylagli, Selasuz and the city of Shahbuz are most exposed to the risks and dangers caused by flood flows. Stabilized landslides of ancient and relatively recent origin have developed in almost all river valleys of the basin. The zone where the landslides spread most actively covers the upper part of the Nakhchivan river basin, the Batabat massif, the Bichenak forest, the middle course of the Kuku river, the settlements of Kechili and Zirnel. Both glacial and debris landslides are widespread here. The factors that cause avalanches in the area differ between low mountains and high mountains. Thus, while in some places frost weathering plays an important role in avalanche formation, in other a sharp change in temperature, the physical and chemical composition of rocks, vegetation, color affecting the heat capacity of rocks, lithological bedding, slope exposure, and degree of inclination, etc., also plays a role. Through the joint analysis of satellite images and field research, for the first time in the basin area, we distinguished some of the dangerous exodynamic processes and were able to prepare maps of them.
