The Main (German pronunciation: [ˈmaɪn] ⓘ) is a river in Germany. With a length of 525 kilometres (326 mi) (including its 52 km long source river White Main), it is the longest right tributary of the Rhine. It is also the longest river lying entirely in Germany (if the Weser and the Werra are considered as two separate rivers; together they are longer). The largest cities along the Main are Frankfurt am Main, Offenbach am Main and Würzburg.[citation needed]

Geography

The mainspring of the Main River flows through the German states of Bavaria, Baden-Württemberg (forming the border with Bavaria for some distance) and Hesse. Its basin competes with the Danube for water; as a result, many of its boundaries are identical with those of the European Watershed.[citation needed]

The Main begins near Kulmbach in Franconia at the joining of its two headstreams, the Red Main (Roter Main) and the White Main (Weißer Main). The Red Main originates in the Franconian Jura mountain range, 50 km (31 mi) in length, and runs through Creussen and Bayreuth. The White Main originates in the mountains of the Fichtelgebirge; it is 41 km (25 mi) long. In its upper and middle section, the Main runs through the valleys of the German Highlands. Its lower section crosses the Lower Main Lowlands (Hanau-Seligenstadt Basin and northern Upper Rhine Plain) to Wiesbaden, where it discharges into the Rhine. Major tributaries of the Main are the Regnitz, the Franconian Saale, the Tauber, and the Nidda.[citation needed]

The name "Main" derives from the Latin Moenus or Menus. It is not related to the name of the city Mainz (Latin: Moguntiacum).[citation needed]

The Main is navigable for shipping from its mouth at the Rhine close to Mainz for 396 km (246 mi) to Bamberg. Since 1992, the Main has been connected to the Danube via the Rhine-Main-Danube Canal and the highly regulated Altmühl river. The Main has been canalized with 34 large locks (300 × 12 m or 984 × 39 ft) to allow CEMT class V vessels (110 × 11.45 m or 360.9 × 37.6 ft) to navigate the total length of the river. The 16 locks in the adjacent Rhine-Main-Danube Canal and the Danube itself are of the same dimensions.[citation needed]

Dams and locks

Dams along the Main

There are 34 dams and locks along the 380 km navigable portion of the Main, from the confluence with the Regnitz near Bamberg, to the Rhine.[2]

  • No.: Number of the lock (from upstream to downstream).
  • Name: Name of the lock.
  • Location: City or town where the lock is located.
  • Year built: Year when the lock was put into operation (replacement dates are also listed where applicable).

  • Distance between locks : length in km of impoundment (between adjacent locks).
  • Altitude: height in meters above mean sea level of the upper water at normal levels.
  • Height: Height of the dam in meters (the height of the Kostheim lock depends on the water level of the Rhine).
  • Lock length: Usable length of the lock chamber in meters.
  • Lock width: Usable width of the lock chamber in meters.

Tributaries

The Main and its main tributaries

Tributaries from source to mouth:

Ports and municipalities

Around Frankfurt are several large inland ports. Because the river is rather narrow on many of the upper reaches, navigation with larger vessels and push convoys requires great skill.

The largest cities along the Main are Frankfurt am Main, Offenbach am Main and Würzburg. The Main also passes the following towns: Burgkunstadt, Lichtenfels, Bad Staffelstein, Eltmann, Haßfurt, Schweinfurt, Volkach, Kitzingen, Marktbreit, Ochsenfurt, Karlstadt, Gemünden, Lohr, Marktheidenfeld, Wertheim, Miltenberg, Obernburg, Erlenbach/Main, Aschaffenburg, Seligenstadt, Hainburg, Hanau, Hattersheim, Flörsheim, and Rüsselsheim.

The river has gained enormous importance as a vital part of European "Corridor VII", the inland waterway link from the North Sea to the Black Sea.[3]

Main line

Main article: Main line (political)

In a historical and political sense, the Main line is referred to as the northern border of Southern Germany, with its predominantly Catholic population. The river roughly marked the southern border of the North German Federation, established in 1867 under Prussian leadership as the predecessor of the German Empire.

The river course also corresponds with the Speyer line isogloss between Central and Upper German dialects, sometimes mocked as Weißwurstäquator.[citation needed]

Recreation

The Main-Radweg is a major German bicycle path running along the Main River. It is approximately 600 kilometres long (370 mi) and was the first long-distance bicycle path to be awarded 5 stars by the General German Bicycle Club ADFC in 2008. It starts from either Creußen or Bischofsgrün and ends in Mainz.[4]
