1911 Encyclopædia Britannica/Ems (river)
EMS, a river of Germany, rising on the south slope of the Teutoburger Wald, at an altitude of 358 ft., and flowing generally north-west and north through Westphalia and Hanover to the east side of the Dollart, immediately south of Emden. After passing through the Dollart the navigable stream bifurcates, the eastern Ems going to the east, and the western Ems to the west, of the island of Borkum to the North Sea. Length, 200 m.
Between 1892 and 1899 the river was canalized along its right bank for a distance of 43 m. At the same time, and as part of the same general plan, a canal, the Dortmund-Ems Canal, was dug to connect the river (from Münster) with Herne in the Westphalian coal-field. At Henrichenburg a branch from Herne (5 m. long) connects with another branch from Dortmund (1012 m. long). Another branch, from Olfen (north of Dortmund), connects with Duisburg, and so with the Rhine. There is, however, a difference in elevation of 46 ft. between the two branches first named, and vessels are transferred from the one to the other by means of a huge lift. The canal, which was constructed to carry small steamers and boats up to 220 ft. in length and 750 tons burden, measures 169 m. in length, of which 10812 m. were actually dug, and cost altogether £3,728,750. The surface width throughout is 9812 ft., the bottom width 59 ft., and the depth 816 ft.
