Major River Systems in the Arctic
The Arctic has several of the world’s largest rivers.This graphic shows the major river systems of the Arctic and their annual discharges in cubic kilometres, and the catchment area of the Arctic Ocean. The major river systems shown are the Mackenzie, Yukon, Nelson, Kolyma, Indigirka, Lena, Kotya, Yenisey, Ob, Pechora, Severnyy and Dvina.

Glacier shrinkage in hypothetical river basins
Downstream variation in the impact of glacier recession is
illustrated in Figure 5, which shows modelled river fows for
idealized catchments under climates representative of the
western and eastern Himalaya and a 0.06º C per year warming scenario. In the upper parts of the river basins, where
glaciers occupy 95% of the catchment area, the impact of glacier shrinkage is large. River discharges increase until mid-century, after which they de...
