Template:Redirect Template:Short description Template:Infobox river

The Main ({{#invoke:IPA|main}}) is the longest tributary of the Rhine, one of the major European rivers. It rises as the White Main in the Fichtel Mountains of northeastern BavariaTemplate:Efn and flows west through central Germany for Template:Convert to meet the Rhine below Rüsselsheim, Hesse. The cities of Mainz and Wiesbaden are close to the confluence.

The largest cities on the Main are Frankfurt am Main, Offenbach am Main and Würzburg.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It is the longest river lying entirely in Germany (if the Weser-Werra are considered separate).

GeographyEdit

The Main flows through the north and north-west of the state of Bavaria and then across southern Hesse; against the latter it demarcates a third state, Baden-Württemberg, east and west of Wertheim am Main, the northernmost town of that state.

The upper end of its basin opposes that of the Danube where the watershed is recognised by natural biologists, sea salinity studies (and hydrology science more broadly) as the European Watershed.

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, Template:Convert in length, and runs through Creussen and Bayreuth. The White Main originates in the Fichtel Mountains; it is Template:Convert 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.<ref>Template:Cite book</ref>

The name Main originates from Latin Moenis, Moenus or Menus. It is not related to the name of the city Mainz (Latin: Mogontiacum or Moguntiacum).

NavigationEdit

The Main is navigable for shipping from its mouth at the Rhine close to Mainz for Template:Cvt 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 (Template:Cvt) to allow CEMT class V vessels (Template:Cvt) 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.Template:Citation Needed

Weirs and locksEdit

Dams along the Main

There are 34 weirs and locks along the 380 km navigable portion of the Main, from the confluence with the Regnitz near Bamberg, to the Rhine.<ref name="wsd">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

  • 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).
  • Main-km: Location on the Main, measured from the 0 km stone in Mainz-Kostheim. The reference point is the center of the lock or lock group.
  • 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).

Ports and municipalitiesEdit

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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Main lineEdit

{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} 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.<ref>Template:Cite book</ref><ref>Template:Cite book</ref>

RecreationEdit

The Main-Radweg is a major German bicycle path alongside the river. Approximately Template:Convert, it is the first long-distance instance awarded 5 stars by the General German Bicycle Club (ADFC) in 2008. It starts from Creußen or Bischofsgrün and ends in Mainz.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
