The role of different links of the river net in forming winter river runoff

Abstract

Results of investigations of the winter river runoff formation in the Northern Dvina River basin (without the Vychegda River basin) are under consideration. The peculiarities of the winter runoff formation are revealed from the analysis of the conditions of the runoff reduction in different parts of the river basin. A regulatory effect of the upper links of the river net on the lower links is established.
