The relevance of the work is due to the fact that exogenous geological processes are caused by external energy sources relative to the Earth (mainly solar radiation) in combination with gravity. They occur both on the surface and in the near-surface zone of the earth's crust in the form of mechanical and physico-chemical interaction with the hydrosphere and atmosphere. These processes produce both destructive and creative work. The processes of weathering and denudation have a destructive effect. Creative work consists in the formation of rocks in new places, as well as in the formation of minerals. The structure of the leading processes in the studied region(Astrakhan Caspian sea) is quite homogeneous and is represented by the following classes of processes - Aeolian, fluvial and karst. Conclusions: a comprehensive assessment of exogenous relief formation within the Astrakhan Volga region is the main task for its further successful economic development, as well as the prevention of dangerous and adverse geomorphological processes.
