LONG-TERM AND WITHIN-YEAR VARIABILITY OF RUNOFF FROM THE RUSSIAN PART OF THE CATCHMENT AREA OF THE WESTERNDVINARIVER, AS A RESPONSE TO FLUCTUATIONS IN CLIMATIC PARAMETERS
The results of the analysis of inter annual and seasonal variability in runoff from the area from the Rus- sian part of the Western Dvina River catchment, as response to temperature and precipitation for the period 1966-2015 are presented. Their spatial-temporal variation is shown. Runoff, depending on the amount of precipitation and air temperature, also has a positive trend, but its change is non-linear with respect to changes in precipitation, but always exceeds them.
