Course
The Danube rises in two sources (the Brege and Brigach rivers) in the Black Forest, SW Germany, and flows NE across S Germany past Ulm to Regensburg, where it turns SE to enter Austria at Passau. It continues SE through Upper and Lower Austria, past Linz and Vienna. It then forms the border between Slovakia and Hungary from Bratislava to Szob. At Szob, the Danube turns south and flows across the Great Alföld (plain) of central Hungary, past Budapest. After forming the northern two thirds of the Croatia-Serbia border, it enters Serbia above Belgrade, turns southeast, then east, and flows through narrow gorges, forming part of the Serbia-Romania border. The Iron Gate gorge, site of a hydroelectric dam, is there; the Sip Canal bypasses rapids in the gorge. After passing the Iron Gate, the Danube broadens again and forms most of the Romania-Bulgaria border before swinging north near Silistra and passing through E Romania to Galaţi, where it divides into an expansive (c.1,000 sq mi/2,590 sq km) delta before entering the Black Sea. The northernmost branch of the delta runs along the frontier between Romania and Moldova and Ukraine. The central, canalized branch is the main shipping route. The Danube receives more than 300 tributaries, notably the Inn, Drava, Tisza, Sava, and Prut.
Navigation and Commerce
Navigable by barges from Ulm (by larger craft from Regensburg), the Danube is an important artery; in volume, however, Danubian commerce is far below that of the Rhine. The Danube is linked to the Main and Rhine rivers by the Rhine-Main-Danube Canal; other canals link it with the Oder and Tisza rivers. Navigation is impeded by ice in winter and by seasonally varying water levels. Hungary and Czechoslovakia (succeeded by Slovakia) agreed in 1977 to develop hydroelectric projects, which have been pursued amid controversy. Pollution of the Danube has diminished once-rich fishing grounds and rendered the water unfit for drinking and most irrigation; cleanup has proceeded slowly. Romanian efforts in the 1980s to drain land in the delta for agriculture damaged Europe's largest wetlands, which are now being rehabilitated. During the Kosovo crisis in 1999, NATO air strikes destroyed bridges across the river in Serbia, obstructing river commerce; the debris was completely cleared in 2003.
History
Under the Roman Empire (when it was known as Danubius and, in its lower course, as Ister), the Danube was the northern border against the barbarian world. As Rome declined, the Danubian plains for centuries attracted invading hordes—Goths, Huns, Avars, Magyars, Pechenegs, Cumans, Mongols, and others. The Danube increased in commercial importance in the era of the Crusades, but commerce suffered (15th–16th cent.) after the Turks gained control of its course from the Hungarian plain to the Black Sea. In the 19th cent. the Danube's economic importance as an international waterway increased. At the end of the Crimean War the Congress of Paris appointed (1856) a commission to clear the delta (below Brăila) of obstructions.
By the Treaty of Versailles (1919) the Danube was internationalized and a commission established with jurisdiction over the course from Ulm to Brăila. Germany repudiated the internationalization in 1936 and in 1939–40 forced both the navigation and international commissions to dissolve. After World War II, delegates from Czechoslovakia, Hungary, Yugoslavia, Romania, Bulgaria, the Soviet Union, the United States, Great Britain, and France met (1948) to determine the status of the Danube. When a commission representing only the seven riparian nations was established, the three Western nations refused to sign the convention. Subsequently, the riparian nations established a new Danube commission, based at Budapest; present membership includes Austria, Bulgaria, Croatia, Germany, Hungary, Moldova, Romania, Russia, Serbia, Slovakia, and Ukraine.

 Danube River
|

The Danube (pronounced /ˈdænjuːb/ in English) is the longest river in the European Union and Europe's second longest river after the Volga.
The river originates in the Black Forest in Germany as the much smaller Brigach and Breg rivers which join at the German town Donaueschingen, after which it is known as the Danube and flows eastwards for a distance of some 2850 km (1771 miles), passing through four Central and Eastern European capitals, before emptying into the Black Sea via the Danube Delta in Romania and Ukraine.
Known to history as one of the long-standing frontiers of the Roman Empire, the river flows through — or forms a part of the borders of — ten countries: Germany (7.5%), Austria (10.3%), Slovakia (5.8%), Hungary (11.7%), Croatia (4.5%), Serbia (10.3%), Romania (28.9%), Bulgaria (5.2%), Moldova (1.7%), and Ukraine (3.8%).[citation needed]

The English language has, since the Norman conquest of England, used the French word Danube. In other languages, particularly those spoken in the locations which the river flows through:
One theory ultimately derives all these variations to the Celtic word *dānu, meaning "to flow".[1] Other theories derive the name from an Iranic root that has contributed the names of all other major rivers emptying into the Black Sea, such as the Don, Donets, Dnieper and Dniestr. Ancient Greek Istros was a borrowing from Thracian meaning "strong, swift", akin to Sanskrit is.iras "swift", Ancient Greek ἱερός (hierós) "strong, sacred".[2]
In addition to the Danubian countries, the drainage basin includes parts of nine more countries: Italy (0.15%), Poland (0.09%), Switzerland (0.32%), the Czech Republic (2.5%), Slovenia (2.2%), Bosnia and Herzegovina (4.8%), the Republic of Macedonia, and Albania (0.03%). The highest point of the drainage basin is the summit of Piz Bernina at the Italy–Switzerland border, 4,049 metres (13,280 ft).
The Danube's watershed extends into many other countries. Many Danubian tributaries are important rivers in their own right, navigable by barges and other shallow-draught boats. From its source to its outlet into the Black Sea, its main tributaries are (in order):

15. Tisza |
The Danube flows through the following countries and cities (from source to mouth ordered):
The Danube flows through four capital cities (shown in bold), more than any other river in the world.
The Danube is navigable by ocean ships from the Black Sea to Brăila in Romania and by river ships to Kelheim, Bavaria; smaller craft can navigate further upstream to Ulm, in Germany. About 60 of its tributaries are also navigable.
Since the completion of the German Rhine–Main–Danube Canal in 1992, the river has been part of a trans-European waterway from Rotterdam on the North Sea to Sulina on the Black Sea (3500 km). In 1994 the Danube was declared one of ten Pan-European transport corridors, routes in Central and Eastern Europe that required major investment over the following ten to fifteen years. The amount of goods transported on the Danube increased to about 100 million tons in 1987. In 1999, transport on the river was made difficult by the NATO bombing of three bridges in Serbia. The clearance of the debris was finished in 2002. The temporary pontoon bridge that hampered navigation was finally removed in 2005.
At the Iron Gate, the Danube flows through a gorge that forms part of the boundary between Serbia and Romania; it contains the hydroelectric Iron Gate I dam, followed at about 60 km downstream (outside the gorge) by the Iron Gate ll dam. On 13 April 2006, a record peak discharge at Iron Gate Dam reached 15,400 m³/s.
There are three artificial waterways built on the Danube: the Danube–Tisa–Danube Canal (DTD) in the Banat and Bačka regions (Vojvodina, northern province of Serbia); the 64 km Danube–Black Sea Canal, between Cernavodă and Constanţa (Romania) finished in 1984, shortens the distance to the Black Sea by 400 km; the Rhine–Main–Danube Canal (about 171 km), finished in 1992, linking the North Sea to the Black Sea.
The Danube Delta has been a UNESCO World Heritage Site since 1991. Its wetlands (on the Ramsar list of wetlands of international importance) support vast flocks of migratory birds, including the endangered Pygmy Cormorant (Phalacrocorax pygmaeus). Rival canalization and drainage scheme threaten the delta: see Bastroe Channel.
Although the headwaters of the Danube are relatively small today, geologically, the Danube is much older than the Rhine, with which its catchment area competes in today's southern Germany. This has a few interesting geological complications. Since the Rhine is the only river rising in the Alps mountains which flows north towards the North Sea, an invisible line beginning at Piz Lunghin divides large parts of southern Germany, which is sometimes referred to as the European Watershed.
However, before the last ice age in the Pleistocene, the Rhine started at the southwestern tip of the Black Forest, while the waters from the Alps that today feed the Rhine were carried east by the so-called Urdonau (original Danube). Parts of this ancient river's bed, which was much larger than today's Danube, can still be seen in (now waterless) canyons in today's landscape of the Swabian Alb. After the Upper Rhine valley had been eroded, most waters from the Alps changed their direction and began feeding the Rhine. Today's upper Danube is but a meek reflection of the ancient one.
Since the Swabian Alb is largely shaped of porous limestone, and since the Rhine's level is much lower than the Danube's, today subsurface rivers carry much water from the Danube to the Rhine. On many days in the summer, when the Danube carries little water, it completely oozes away noisily into these underground channels at two locations in the Swabian Alp, which are referred to as the Donauversickerung (Danube Sink). Most of this water resurfaces only 12 km south at the Aachtopf, Germany's wellspring with the highest flow, an average of 8500 litres per second, north of Lake Constance — thus feeding the Rhine. The European Water Divide thus in fact only applies for those waters that pass beyond this point, and only during the days of the year when the Danube carries enough water to survive the sink holes in the Donauversickerung.
Since this enormous amount of underground water erodes much of its surrounding limestone, it is estimated that the Danube upper course will one day disappear entirely in favor of the Rhine, an event called stream capturing.

The Danube basin was the site of some of the earliest human cultures. The Danubian Neolithic cultures include the Linear Pottery cultures of the mid-Danube basin. The third millennium BC Vučedol culture (from the Vučedol site near Vukovar, Croatia) is famous for its ceramics. Many sites of the sixth-to-third millennium BC Vinča culture are sited along the Danube. The river was part of the Roman empire's Limes Germanicus.
Of importance for the Danube is also the International Commission for the Protection of the Danube River (ICPDR). The ICPDR is an international organisation consisting of 13 member states (Germany, Austria, the Czech Republic, Slovakia, Slovenia, Hungary, Croatia, Bosnia and Herzegovina, Serbia, Bulgaria, Romania, Moldova, Ukraine) and the European Union. ICPDR, established in 1998, deals not only with the Danube itself, but with the whole Danube River Basin, which also includes its tributaries and the groundwater resources. The goal of the ICPDR is to implement the Danube River Protection Convention, promoting and coordinating sustainable and equitable water management, including conservation, improvement and rational use of waters for the benefit of the Danube River Basin countries and their people. The Romans often used the river Danube as a border for their vast empire.
Part of the Danubius or Istros river was also known as (together with the Black Sea) the Okeanos in ancient times, being called the Okeanos Potamos (Okeanos River). The lower Danube was also called the Keras Okeanoio (Gulf or Horn of Okeanos) in the Argonautica by Apollonius Rhodos (Argon. IV. 282). Okeanos was not originally a Greek word (Thalassa being Greek for sea), Okeanos being a Pelasgian word which was similar to eye (ochio) and water (aqua) with the Pelasgian ending an-os, which could have meant large still water (not a sea). The lower Danube has a slow deep wide course, so it can be seen why it was considered as part of the Okeanos.
Both Homer (Odyss. XII. 1) and Hesiod (Theogonia, v.242. 959) in their theogonic legends exclusively refer to the lower Danube as the Okeanos Potamos, possibly due to it being remembered as the remnant of when the Pannonian and lower Danubian basins were under water.
At the end of the Okeanos Potamos, is the holy island of Alba (Leuke, Pytho Nisi, Isle of Snakes), sacred to the Pelasgian (and later, Greek) Apollo, greeting the sun rising in the east. Hecateus Abderitas refers to Apollo's island from the region of the Hyperboreans, in the Okeanos. It was on Leuke, in one version of his legend that the hero Achilles was buried (to this day, one of the mouths of the Danube is called Chilia). Old Romanian folk songs sing of a white monastery on a white island with nine priests.[3]
The Danube Bike Trail (also called Danube Cycle Path or the Donauradweg) is a bicycle trail along the river.
The Danube Bike Trail (Donauradweg) is divided into four sections:
The Danube is mentioned in the title of a famous waltz by Austrian composer Johann Strauss, An der schönen, blauen Donau (On the Beautiful Blue Danube). This piece was composed as Strauss was traveling down the Danube River.[citation needed] This piece is well known across the world and is also used widely as a lullaby.
Another famous waltz about the Danube is The Waves of the Danube (Romanian: Valurile Dunării) by the Romanian composer Ion Ivanovici (1845–1902), and the work took the audience by storm when performed at the 1889 Paris Exposition.
Joe Zawinul wrote a symphony about the Danube called Stories of the Danube. It was performed for the first time at the 1993 Bruckner festival, at Linz.
The Danube figures prominently in the Bulgarian National Anthem, as a symbolic representation of the country's natural beauty.
The German tradition of landscape painting, the Danube school, was developed in the Danube valley in the 16th century.
The most famous book describing the Danube might be Claudio Magris's masterpiece Danube (ISBN 1-86046-823-3).
The historical fiction Earth's Children series by Jean M. Auel refers to the Danube as the Great Mother River.
The river is the subject of the film The Ister (official site here).
Parts of the German road movie Im Juli take place along the Danube.
Noted horror writer Algernon Blackwood's most famous short story, "The Willows" concerned a trip down the Danube.
In the PC Space Simulator Freelancer the battle cruiser Donau is destroyed during the first cutscene.
In the Star Trek universe, a class of spacecraft was named after the Danube.
Along its path, the Danube is a source of drinking water for about ten million people. In Baden-Württemberg, Germany, almost thirty percent (as of 2004) of the water for the area between Stuttgart, Bad Mergentheim, Aalen and Alb-Donau (district) comes from purified water of the Danube. Other cities like Ulm and Passau also use some water from the Danube.
In Austria and Hungary, most water comes from ground and spring sources, and only in rare cases is water from the Danube used. Most states also find it too difficult to clean the water because of extensive pollution; only parts of Romania where the water is cleaner still use a lot of drinking water from the Danube.[citation needed]
As "Corridor VII" of the European Union, the Danube is an important transport route. Since the opening of the Rhine–Main–Danube Canal, the river connects the Black Sea with the industrial centers of Western Europe and with the Port of Rotterdam. The waterway is designed for large scale inland vessels (110×11.45 m) but it can carry much larger vessels on most of its course. The Danube has been partly canalized in Germany (5 locks) and Austria (10 locks). Further proposals to build a number of new locks in order to improve navigation have not progressed, due in part to environmental concerns.
Downstream from the Freudenau river plant's locks in Vienna, canalization of the Danube was limited to the Gabčíkovo dam and locks near Bratislava and the two double Iron Gate locks in the border stretch of the Danube between Serbia and Romania. These locks have larger dimensions (similar to the locks in the Russian Volga river, some 300 by over 30 m). Downstream of the Iron Gate, the river is free flowing all the way to the Black Sea, a distance of more than 860 kilometers.
The Danube connects with the Rhine–Main–Danube Canal at Kelheim, and with the Wiener Donaukanal in Vienna. Apart from a couple of secondary navigable branches, the only major navigable rivers linked to the Danube are the Drava, Sava and Tisza. In Serbia, a canal network also connects to the river; the network, known as the Dunav-Tisa-Dunav canals, links sections downstream.
The importance of fishing on the Danube, which used to be critical in the Middle Ages, has declined dramatically. Some fishermen are still active at certain points on the river, and the Danube Delta still has an important industry.
Important tourist and natural spots along the Danube include the Wachau valley, the Nationalpark Donau-Auen in Austria, Gemenc in Hungary, the Naturpark Obere Donau in Germany, Kopački rit in Croatia, Iron Gate and Danube Delta in Romania, the Srebarna Nature Reserve in Bulgaria.
