Dnieper (D'nee'pr; anc. Borysthenes), a river rising near the Volga and Western Dwina, in the N. of the Russian province of Smolensk, and flowing 1330 miles southward past Kieff, Ekaterinoslav, and Alexandrovsk to the Black Sea. Its embouchure (increased by the waters of the Bug) forms a gulf nearly 50 miles long, and 1 to 6 miles broad. Its principal affluents are the Desna and Soj from the east, and the Pripet, Beresina, and Druz from the west. At Dorogo-bush the stream becomes navigable, but below Kieff and at other points traffic is interrupted. The produce of the southern provinces is usually conveyed down the river to ports on the Black Sea, but many vessels pass annually from the Dnieper to the Baltic by the Brest-Litovsk canal (50 miles) and other water-ways. The stream is permanently bridged at Kieff only. At Smolensk, its waters are frozen from November to April; at Kieff, only from January to the end of March; and at Kherson it is frequently open all the year.
