Main

(mīn), river, c.310 mi (500 km) long, formed near Kulmbach, E central Germany, by the confluence of the Roter Main and the Weisser Main, both of which rise in the Fichtelgebirge. It then winds generally west through the rich farmland of central Germany and past the industrial areas of Schweinfurt, Würzburg, Aschaffenburg, and Frankfurt to the Rhine River at Mainz. Navigable from its junction with the Regnitz River, its chief tributary, the Main is an important east-west route. The Ludwig Canal connects it with the Danube River. A recently completed addition to the canal links the Danube with the Rhine, allowing barge traffic from the North Sea to the Black Sea, a distance of more than 2,000 mi (3,200 km). There are about 40 hydroelectric power plants on the Main, of which Griesheim (62,000-kW capacity) is the largest.

Main

 

a river in the Federal Republic of Germany; the largest right-bank tributary of the Rhine. Length, 524 km; basin area, 27,200 sq km.

The Main is formed by the confluence of the Red Main, which rises on the slopes of the Fränkische Alb, and the White Main, which rises in the Fichtelgebirge mountains. For most of its length the Main flows amid hills in a narrow valley and across a plain. Its high-water period occurs during the winter and the beginning of spring; there are flash floods in the summer, owing to rain. The water level in the Main’s lower course fluctuates by 2-3 m; the average discharge at the mouth is 170 cu m per sec. The Main is navigable for a distance of almost 400 km from the mouth. The Main valley is densely populated, with such cities as Wiirzburg and Frankfurt being located on the river. The waters of the Main are extremely polluted.

a river in Chukchi National Okrug, Magadan Oblast, RSFSR. A right-bank tributary of the Anadyr’ River. Length, 475 km; basin area, 32,800 sq km. The Main rises on the slopes of the Penzhina Range from Lake Main. It flows northeast, for the most part within a broad valley; in its lower course it breaks up into branches. It is fed by snow and rain. The average discharge is about 260 cu m per sec. The Main freezes over in mid-October, and the ice breaks up at the end of May. In its lower course the river is navigable during the high-water period by shallow-draft vessels.
