On the example of the mountain rivers of the SamurAbsheron massif, the Republic of Azerbaijan analyzed the consequences of anthropogenic disturbances of the river bed. The main role in the disturbance of the channel was played by the development of channel quarries of building materials (during for almost 25 years). The study site captured the lower reaches of the intake structure which of the built on these rivers. Trends in the development of the channel process are revealed before and during the period of the action of anthropogenic disturbances. The volume of sand-gravel material irretrievably removed from the bed has been estimated, the depth of deformations have been revealed. Аppropriate formulas were proposed to calculate the stability of the newly formed sustainable bottom slope, taking into account the physical and mechanical properties of the riverbed and the flow rate.
