Anthropogenic impact on the runoff of Russian rivers emptying into the Arctic Ocean

The effect of water consumption and reservoirs on the regime and water resources of Russian rivers emptying into the Arctic Ocean is discussed. The impact of reservoirs on the annual and seasonal runoff of regulated rivers is estimated. The transformation of this impact along the rivers down to their outlet sections is analyzed. Possible variants of the development of water management measures in Arctic river basins in the first quarter of the 21st century are considered.
