The Oise ( /wɑːz/ WAHZ; French:  [waz] ( Loudspeaker.svg listen )) is a river of Belgium and France, flowing for 341 km (212 mi) [1] from its source in the Belgian province of Hainaut, south of Chimay. It crosses the border with France after about 20 km (12 mi). It flows into the Seine at Conflans-Sainte-Honorine, a north-western suburb of Paris. Its main tributary is the Aisne. It gave its name to the French departments of Oise and Val-d'Oise.


Places along the river

In France, the Oise flows through the following départements and towns:

Over the past few centuries, the Oise has played an important role as an inland shipping waterway connecting the Seine (and thus Paris) with the coastal regions of northern France, Belgium, and the Netherlands. With the projected construction of the Seine-Nord Europe Canal, a high-capacity water transport system currently in development, the Oise will be linked at Janville, north of Compiègne, with the high-capacity Canal Dunkerque-Escaut, east of Arleux. The Seine-Nord Europe Canal will replace the old Canal de Saint-Quentin and the current Canal du Nord, the capacity of which is far below standard. When the new Seine-Nord connection is complete, it will allow large vessels to transport goods from the Seine, and thus Paris and its surrounding area, to the ports of Dunkirk, Antwerp and Rotterdam.

Part of the overall project consists in upgrading the river Oise itself between Creil and Compiègne, a project called MAGEO (Mise au gabarit européen de l'Oise) that was put out to public consultation in 2013. Some bends need to be eased and bridges raised to meet the requirements of a class Vb inland waterway. [2]

The Scheldt is a 350-kilometre-long (220 mi) river that flows through in northern France, western Belgium, and the southwestern part of the Netherlands, with its mouth at the North Sea.

Saint Honorina is venerated as a saint by the Catholic Church. She is the oldest, most revered virgin martyr in the Normandy area of France but little is known of her. According to a tradition that exists in the diocese of Rouen, Honorina, a member of the Calates, was martyred during the persecutions of Diocletian. The spot of her martyrdom is said to have been Mélamare between Lillebonne and Harfleur. Her body was thrown into the Seine and would have drifted to Graville-Sainte-Honorine, where it was collected by Christians and buried in a tomb.

Canal du Nord Canal in northern France

The Canal du Nord is a 95-kilometre (59 mi) long canal in northern France. The canal connects the Canal latéral à l'Oise at Pont-l'Évêque to the Sensée Canal at Arleux. The French government, in partnership with coal-mining companies in the Nord and Pas-de-Calais departments, developed the canal to help French coal mining companies withstand foreign competition. Construction of the canal began in 1908 but halted in 1914, because of the First World War. The war caused widespread destruction of the canal and the French government made no attempt to resume construction until 1959. Construction recommenced in 1960 and the waterway opened to the public in 1965. The Canal du Nord and the Canal de Saint-Quentin may be supplanted by the Seine–Nord Europe Canal, a projected high capacity link between the Oise River at Janville and the high capacity Dunkirk-Escaut Canal.

Seine–Nord Europe Canal canal

The Seine–Nord Europe Canal is a projected high-capacity canal in France that would link the Oise River at Compiègne with the Canal Dunkerque-Escaut, east of Arleux. It is the French part of a proposed Seine-Scheldt canal that would ultimately connect the Rhine and Seine basins inland. The stated objective is to expand trade flows in a fuel-efficient and ecologically friendly manner between the Seine basin and Belgium, Germany and the Netherlands, while reducing saturation on the A1 motorway in France and reducing the CO2 emissions in the transport sector within this corridor.

The canal rises 40m through 16 locks via the cathedral city of Reims, which is also a busy commercial port, to a summit level at an altitude of 95.70m. After crossing the watershed through a tunnel 2302m long at Mont-de-Billy, the canal drops down 23.80m through a flight of 8 locks towards the Marne.

Canal latéral à lOise Canal in northern France

The Canal latéral à l'Oise is a canal in northern France that, along with the river Oise, connects the Canal de Saint-Quentin at Chauny to the Seine at Conflans-Sainte-Honorine. See under the river Oise for the continuation of the route; the junction is made downstream of the lock at Janville 49.45750°N 2.85933°E. When a canal is latéral, it follows the course of the river it is named after but in a separate excavated channel. The route described below is the 34 km of canal parallel to the river Oise and 103.5 km of the canalised river Oise.

Canal de Saint-Quentin canal

Canal Dunkerque-Escaut architectural structure

The Canal Dunkerque-Escaut is a 189 km long series of historic canals, and the canalised river Escaut (Scheldt) that were substantially rebuilt from the mid-1950s up to ca. 1980, with some new sections, from Dunkerque to the Belgian border at Mortagne-du-Nord. Existing canals were straightened and widened; and new locks (écluses) were built, also on the river Escaut, from the junction at Bouchain to the border. The route is also known as the Liaison 'à grand gabarit'Dunkerque-Escaut. Some authors have separated the waterway into the canal proper and the canalised river Escaut, but current practice is to use the simple name throughout. The Liaison was designed for large commercial vessels up to 85m long by 11.50m wide. The entire route is being further upgraded to offer European Class Vb dimensions, for push-tows 185m by 11.50m, and motor barges up to 125m long, as part of the current EU-funded Seine-Escaut-Rhine waterway corridor investments, including the new Seine-Nord Europe Canal.

The railway from Creil to Jeumont is an important French 187-kilometre long railway line, that connects Creil, a northern suburb of Paris, to Jeumont on the Belgian border. It was opened in several stages between 1847 and 1855. The opening of the LGV Nord high speed line from Paris to Lille in 1993 has decreased its importance for passenger traffic.
