The Seine (pronounced /sɛn/ in French) is a major river of north-western France, and one of its commercial waterways. It is also a tourist attraction, particularly within the city of Paris.

The Seine starts near Dijon in northern France flows through Paris and into the English Channel.
Further downstream in what is now Normandy, the Seine was known as Rodo, or Roto, which is a traditional Celtic name for rivers, and is also the original name of the Rhône River (see Rhône article for further explanations). This is proved by the name of Rouen, which was Rotomagos in Gaulish, meaning "field, plain (magos in Gaulish, whose meaning evolved into "market") of the Roto".The Seine is dredged and oceangoing vessels can dock at Rouen, 120 km (75 miles) from the sea. Commercial riverboats can use the river from Bar-sur-Seine, 560 km (350 miles) from its mouth. At Paris, the river is only 24 metres (80 feet) above sea level, 445 km (277 miles) from its mouth, making it slow flowing and thus easily navigable. It is 776 km (486 miles) long and flows into the Atlantic Ocean from the continent.
The tidal section of the river, from Le Havre to well beyond Rouen, is followed by a canalized section with four large multiple locks until the mouth of the Oise river at Conflans-Sainte-Honorine. Then two more 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 River is located. Upstream from Paris seven more locks ensure navigation to Saint Mammès (where the Loing mouth is situated). Through an eighth lock the river Yonne is reached at Monterau. From the mouth of the Yonne, larger ships can continue upstream the Seine till Nogent-sur-Seine. From there on, the river is only navigable for 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 now. (Source: NoorderSoft Waterways Database)
The average depth of the Seine today at Paris is about 8 meters. Until locks were installed to artificially raise the level in the 1800s, however, the river was much shallower within the city most of the time, and consisted only of a small channel of continuous flow bordered by sandy banks (visible in many illustrations of the period). Today 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[citation needed], 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.
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.Seine River Basin, United Nations Environment Programme Department of Early Warning and Assessment (accessed 5 June 2007 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 be flooded."Fearing a Big Flood, Paris Moves Art" by Alan Riding, New York Times, February 19, 2003 A 2002 report by the French government stated the worst-case Seine flood scenario would cost 10 billion Euros, cut telephone service for a million Parisians, leave 200,000 without electricity and 100,000 without gas."Paris flood warning" by Rory Mulholland, BBC News, 25 January 2002
Until the 1930s, a towing system using a chain on the bed of the river existed to facilitate movement of barges upriver.

Under these conditions untreated sewage has been discharged into the SeineMartin Seidl, The fate of organic matter in river Seine after a combined sewer overflow, ENPC - University Paris Val de Marne Paris XII (France), 1997, 181 pp.. The resulting oxygen deficit is principally caused by allochthonous bacteria larger than one micrometer in size. The specific activity of these sewage bacteria is typically three to four times greater than that of the autochthonous (background) bacterial population. The pH level of the Seine at Pont Neuf has been measured to be 8.46Hogan, C Michael, Water quality of fresh water bodies in France, Lumina Press, Aberdeen 2006
The Seine River was one of the original objectives of Operation Overlord in 1944. The Allies\' intention was to reach the Seine by D+90 (ie 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.
Joan of Arc\'s ashes were thrown into the Seine.
Dredging in the 1960s mostly eliminated tidal bores on the river, known as “le mascaret.”
The Banks of the Seine in Paris were added to the UNESCO\'s list of World Heritage Sites in 1991.
