DVINA , the name of two See also:rivers of See also:European See also:Russia.
1. The See also:NORTHERN DVINA, Or Dvina Syevernaya, belongs to the See also:basin of the See also:- WHITE
- WHITE, ANDREW DICKSON (1832– )
- WHITE, GILBERT (1720–1793)
- WHITE, HENRY KIRKE (1785-1806)
- WHITE, HUGH LAWSON (1773-1840)
- WHITE, JOSEPH BLANCO (1775-1841)
- WHITE, RICHARD GRANT (1822-1885)
- WHITE, ROBERT (1645-1704)
- WHITE, SIR GEORGE STUART (1835– )
- WHITE, SIR THOMAS (1492-1567)
- WHITE, SIR WILLIAM ARTHUR (1824--1891)
- WHITE, SIR WILLIAM HENRY (1845– )
- WHITE, THOMAS (1628-1698)
- WHITE, THOMAS (c. 1550-1624)
White See also:Sea, and is formed by the junction of the Sukhona and the Yug, which, rising, the former in the See also:south-See also:west and the latter in the south-See also:east of the See also:government of See also:Vologda, meet in the neighbourhood of Velikiy-Ustyug, at a height of 300 ft. above the sea, in 61° 20' N. and 46° 20' E. The conjoint stream then flows N.W. to the Gulf of See also:Archangel, which it reaches 50 M. below the See also:city of Archangel. From its mouth to the confluence of the co-tributary streams the distance is about 470 m., and to the source of the Sukhona 78o m. The drainage See also:area is estimated at 141,000 sq. m. Except at the rapids the current of the Dvina is comparatively slow, as the See also:average fall per mile is only 9 in. Till its See also:union with the Vychegda, a See also:river which exceeds it in See also:volume, it flows for the most See also:part in a single, well-defined and permanent channel; but below that point it often splits into several branches, and not infrequently alters its course. In the neighbourhood of Archangel it divides into three distinct arms, which See also:form a See also:regular See also:delta; but of these that of See also:Berezov alone is navigable for sea-going vessels, and even it is impeded by a See also:bar at the mouth, with not more than 141 or 152 ft. of See also:water at full See also:tide. Just above the point where the delta begins the river is joined by a large tributary, the Pinega, from the right. Above the confluence of the Vychegda the breadth is about 1750 ft.; below that point it widens out to 3500 ft.; and near Archangel it attains more than three times that measure. The channel is See also:free from See also:ice for about 174 days in the See also:year. By means of the See also:Duke See also:Alexander of See also:Wurttemberg See also:Canal, the river is connected with the See also:Neva and the See also:Volga.
2. The See also:SOUTHERN DVINA, or Dvina Zapadnaya, in See also:German See also:Dana and in Lettish Daugava, belongs to. the Baltic basin, and takes its rise in a small See also:lake about 800 ft. above the level of the sea, in the government of See also:Tver, not far from the See also:sources of the Volga and the See also:Dnieper. After dividing Tver in part from See also:Pskov in part, it skirts the east and south of the government of See also:Vitebsk, separates part of the latter from See also:Vilna, and then divides Vitebsk ,and See also:Livonia from Couriand, and disembogues in the southern end of the Gulf of See also:Riga. Its length is 64o m. and it drains an area of 32,960 sq. m. From See also:Dvinsk (Diinaburg) to Riga, a distance of 135 m., there is altogether a fall of 295 ft., of which 105 ft. are in the 40 M. from Jakobstadt to Friedrichstadt. In the See also:lower part of its course the river attains an See also:ordinary See also:depth of 30 ft. and an average breadth of 1400 ft.; but during the See also:spring See also:flood it sometimes rises 14 ft. above its usual level, and its See also:waters spread out to a mile in width. Near the mouth the river is . usually free from ice for 245 days in the year, and in the government of Vitebsk for 229. It is navigable from the confluence of the Mezha (i.e. from Vitebsk) downwards, but the number of rapids and shallows greatly diminishes its value. See also:Navigation can also be carried on by the following tributaries: the Usvyat, Mezha, Kasplya, Ulla, Disna and Bolder-aa. This river was formerly called the Khezin or Turunt, and at the See also:present See also:day it has the name of Polot among the White Russians. See also:Salmon and lampreys abound in its waters. (P.
