Development of Channel and Floodplain Quarry on the Verkhnyaya Belaya River and Their Influence on Channel Deformations and Navigation Conditions

Active work on the extraction of non-metallic building materials in existing quarries leads to deterioration of hydrological and navigation conditions. On the upper part of the Belaya River, the provision of guaranteed depths is reduced. Significant deformations of the river bed occurred due to the large number of quarries. A long period of time and almost complete abandonment of quarry workings in the riverbed is needed to restoring the natural course of riverbed processes and the water level in the river.
