Dvina

Dvina (German, Düna), name of two rivers, eastern and north-eastern Europe.

The Northern Dvina (Russian Severnyaya Dvina) is formed by the union of the Sukhona and Yug rivers, in northern European Russia. After a north-western course of about 748 km (465 mi), it flows through Dvina Bay into the White Sea. The main tributaries are the Vychegda, Vaga, and Pinega rivers. After its juncture with the Pinega, just below the city of Archangel, the Northern Dvina forms an extensive delta. The Northern Dvina is frozen from December until April and is navigable only during the warmer months from its confluence with the Vychegda River to the White Sea. The river is used to ship timber.
