Sensitivity Analysis of Discharge in the Arctic Usa Basin East-European Russia
The high sensitivity of the Arctic implies that impact of climate change and related environmental changes on river discharge can be considerable. Sensitivity of discharge to changes in precipitation, temperature, permafrost and vegetation, was studied in the Usa basin, Northeast- European Russia. F...

The high sensitivity of the Arctic implies that impact of climate change and related environmental changes on river discharge can be considerable.
