The Seine (/sn/ SAYN; French: La Seine, pronounced: [la sɛːn]) is a 776-kilometre (482 mi) long river and an important commercial waterway within the Paris Basin in the north of France. It rises at Source-Seine, 30 kilometres (19 mi) northwest of Dijon in northeastern France in the Langres plateau, flowing through Paris and into the English Channel at Le Havre (and Honfleur on the left bank).[1] It is navigable by ocean-going vessels as far as Rouen, 120 kilometres (75 mi) from the sea. Over 60 percent of its length, as far as Burgundy, is negotiable by commercial riverboats and nearly its whole length is available for recreational boating; excursion boats offer sightseeing tours of the Rive Droite and Rive Gauche within the city of Paris.

There are 37 bridges within Paris and dozens more spanning the river outside the city. Examples in Paris include the Pont Louis-Philippe and Pont Neuf, the latter of which dates back to 1607. Outside the city, examples include the Pont de Normandie, one of the longest cable-stayed bridges in the world, which links Le Havre to Honfleur.

Origin of the name

The name "Seine" comes from the Latin Sequana.[2] Some[who?] have argued that Sicauna is cognate to the name of the river Saône. On the other hand, a suggested relationship to the River Shannon in Ireland is unlikely, given the very different forms of the two. (Gaelic an tSiona, dative Sionainn, is from Prehistoric Irish *Sinona. Another proposal has it that Sequana is the Latin version of the Gaulish Issicauna Lower-Icauna, which would be the diminutive of Icauna, which was the Gaulish name of the Yonne.) Some believe the ancient Gauls considered the Seine to be a tributary of the Yonne, which indeed presents a greater average discharge than the Seine. (The river flowing through Paris would be called Yonne if the standard rules of geography were applied.)

Some identify the river Sikanos, origin (according to Thucydides) of the Sicanoi of Sikelia (Sicily), with the river Sequana (Seine).[3][dubious ]

According to Pierre-Yves Lambert, a specialist of the Gaulish language, Sequana retains QV [kʷ], that is unusual in Gaulish, which is normally a P-Celtic language, but he compares with the month name EQVOS, read on the Coligny Calendar. The name of the Gaulish tribe Sequani derives from it.[4]

The digram QV of Sequana could recover a whole syllable, that is to say [se-ku-wa-na],[5] like ucuetis [u-ku-we-tis], but its meaning remains unknown.

Sources

The Seine Source

Seine source

The source where the Seine rises, in the commune of Source-Seine, has been owned by the city of Paris since 1864. A number of closely associated small ditches/depressions provide the source waters, with an artificial grotto laid out to highlight and contain a deemed main source. The grotto includes a statue of a nymph. On the same site are the buried remains of a Gallo-Roman temple. Small statues of the dea Sequana "Seine goddess" and other ex voti found at the same place are now exhibited in the Dijon archeological museum.

The Seine course

The Seine can artificially be divided into five parts :

  • the Petite Seine "Small Seine" from the sources to Montereau-Fault-Yonne
  • the Haute Seine "High Seine" from Montereau-Fault-Yonne to Paris
  • the Traversée de Paris "the Paris waterway"
  • the Basse Seine "Low Seine" from Paris to Rouen
  • the Seine maritime "Maritime Seine" from Rouen to the English channel.

Navigation

The Pont de Normandie over the Seine, between Le Havre and Honfleur, on the Normandy coast

The Seine is dredged and oceangoing vessels can dock at Rouen, 120 kilometres (75 mi) from the sea. Commercial riverboats can use the river from Bar-sur-Seine, 560 kilometres (350 mi) to its mouth. At Paris, there are 37 bridges. The river is only 24 metres (79 ft) above sea level 446 kilometres (277 mi) from its mouth, making it slow flowing and thus easily navigable.

The Seine Maritime, 105.7 kilometres (65.7 mi) from the English Channel at Le Havre to Rouen, is the only portion of the Seine used by ocean-going craft.[6] The tidal section of the Seine Maritime is followed by a canalized section with four large multiple locks until the mouth of the Oise at Conflans-Sainte-Honorine. Multiple locks at Bougival / Chatou and at Suresnes lift the vessels to the level of the river in Paris, where the mouth of the Marne is located. Upstream from Paris seven locks ensure navigation to Saint Mammès, where the Loing mouth is situated. Through an eighth lock the river Yonne is reached at Montereau-Fault-Yonne. From the mouth of the Yonne, larger ships can continue upstream to Nogent-sur-Seine. From there on, the river is navigable only by small craft. All navigation ends abruptly at Marcilly-sur-Seine, where the ancient Canal de la Haute-Seine used to allow vessels to continue all the way to Troyes. This canal has been abandoned for many years.[7]

The average depth of the Seine today at Paris is about 9.5 metres (31 ft). Until locks were installed to raise the level in the 1800s, the river was much shallower within the city most of the time, and consisted of a small channel of continuous flow bordered by sandy banks (depicted in many illustrations of the period). Today the depth is tightly controlled and the entire width of the river between the built-up banks on either side is normally filled with water. The average flow of the river is very low, only a few cubic metres per second, but much higher flows are possible during periods of heavy runoff. Special reservoirs upstream help to maintain a constant level for the river through the city, but during periods of extreme runoff significant increases in river level may occur.

Flooding

A very severe period of high water in January 1910 produced extensive flooding throughout the city. The Seine again rose to threatening levels in 1924, 1955, 1982 and 1999–2000.[8] After a first-level flood alert in 2003, about 100,000 works of art were moved out of Paris, the largest relocation of art since World War II. Much of the art in Paris is kept in underground storage rooms that would have been flooded.[9] A 2002 report by the French government stated the worst-case Seine flood scenario would cost 10 billion euros and cut telephone service for a million Parisians, leaving 200,000 without electricity and 100,000 without gas.[10]

Watershed

The basin area is 78,910 square kilometres (30,470 sq mi),[11] 2 percent of which is forest and 78 percent cultivated land. In addition to Paris, three other cities with a population over 100,000 are in the Seine watershed: Le Havre at the estuary, Rouen in the Seine valley and Rheims at the northern limit—with an annual urban growth rate of 0.2 percent.[11] The population density is 201 per square kilometer.

Water quality

Periodically the sewerage systems of Paris experience a failure known as sanitary sewer overflow, often in periods of high rainfall. Under these conditions untreated sewage has been discharged into the Seine.[12] The resulting oxygen deficit is principally caused by allochthonous bacteria larger than one micrometre in size. The specific activity of these sewage bacteria is typically three to four times greater than that of the autochthonous (background) bacterial population. Heavy metal concentrations in the Seine are relatively high.[13] The pH level of the Seine at Pont Neuf has been measured to be 8.46. Despite this, the water quality has improved significantly over what several historians at various times in the past called an "open sewer".[14]

In 2009, it was announced that Atlantic salmon had returned to the Seine.[15]

After the burning at the stake of Joan of Arc in 1431, her ashes were thrown into the Seine from the medieval stone Mathilde Bridge at Rouen, though unserious counter-claims persist.[16]

According to his will, Napoleon, who died in 1821, wished to be buried on the banks of the Seine. His request was not granted.

At the 1900 Summer Olympics, the river hosted the rowing, swimming, and water polo events.[17] Twenty-four years later, it hosted the rowing events again at Bassin d'Argenteuil, along the Seine north of Paris.[18]

Until the 1930s, a towing system using a chain on the bed of the river existed to facilitate movement of barges upriver.[citation needed]World Canals by Charles Hadfield, David and Charles 1986

The Seine was one of the original objectives of Operation Overlord in 1944. The Allies' intention was to reach the Seine by 90 days after D-Day. That objective was met. An anticipated assault crossing of the river never materialized as German resistance in France crumbled by early September 1944. However, the First Canadian Army did encounter resistance immediately west of the Seine and fighting occurred in the Forêt de la Londe as Allied troops attempted to cut off the escape across the river of parts of the German 7th Army in the closing phases of the Battle of Normandy.

Some of the Algerian victims of the Paris massacre of 1961 drowned in the Seine after being thrown by French policemen from the Pont Saint-Michel and other locations in Paris.

Dredging in the 1960s mostly eliminated tidal bores on the lower river, known in French as "le mascaret."

In 1991 UNESCO added the banks of the Seine in Paris—the Rive Gauche and Rive Droite—to its list of World Heritage Sites in Europe.[19]

Since 2002 Paris-Plages has been held every summer on the Paris banks of the Seine: a transformation of the paved banks into a beach with sand and facilities for sunbathing and entertainment.

The river is a popular site for both suicides and the disposal of bodies of murder victims.[20] In 2007, 55 bodies were retrieved from its waters; in February 2008, the body of supermodel-turned-activist Katoucha Niane was found there.[20]

In art

During the 19th and the 20th centuries in particular the Seine inspired many artists, including:
