30-598: It is a right tributary to the river Meuse . The Ourthe is formed at the confluence of the Ourthe Occidentale (Western Ourthe) and the Ourthe Orientale (Eastern Ourthe), west of Houffalize . The source of the Ourthe Occidentale is near Libramont-Chevigny , in the Belgian province Luxembourg . The source of the Ourthe Orientale is near Gouvy , also in the Belgian province Luxembourg, close to

60-549: A major communication route the River Meuse is the origin of Mosan art , principally (Wallonia and France). The first landscape painted in the Renaissance was the landscape of Meuse by Joachim Patinir . He was likely the uncle of Henri Blès , who is sometimes defined as a Mosan landscape painter active during the second third of the 16th century (i.e. second generation of landscape painters). The main tributaries of

90-691: A meander of the Ourthe. In the south, near Marcourt, there is another high cliff where the Hermitage and chapel of Saint-Thibaut is located. Around 1820, William I of the Netherlands demanded the creation of the Ourthe channel. Via the Ourthe, this channel would have connected the Meuse basin with the Moselle basin. Belgium's independence in 1830 put an end to these plans. The main remnant of these works

150-521: Is a former distributary of the river Maas (or Meuse ), which runs parallel to the current canalised Bergse Maas . The hydrological distribution of the Maas changed during the later Middle Ages, when a major flood forced it to shift its main course towards the Merwede river. However, during another series of severe floods the Maas found an additional path towards the sea near Geertruidenberg , resulting in

180-571: Is joined by the Sambre . Beyond Namur the Meuse winds eastwards and passes Liège before turning north. The river then forms part of the Belgian-Dutch border, except that at Maastricht the border lies further to the west. In the Netherlands it continues northwards through Venlo closely along the border to Germany, then turns towards the west, where it runs parallel to the Waal and forms part of

210-543: Is navigable over a substantial part of its total length: In the Netherlands and Belgium, the river is part of the major inland navigation infrastructure, connecting the Rotterdam-Amsterdam-Antwerp port areas to the industrial areas upstream: 's-Hertogenbosch, Venlo, Maastricht, Liège, Namur. Between Maastricht and Maasbracht , an unnavigable section of the Meuse is bypassed by the 36 km (22.4 mi) Juliana Canal . South of Namur, further upstream,

240-690: Is the unfinished channel tunnel in Bernistap (province of Luxembourg). Meuse The Meuse or Maas is a major European river , rising in France and flowing through Belgium and the Netherlands before draining into the North Sea from the Rhine–Meuse–Scheldt delta . It has a total length of 925 km (575 miles). From 1301, the upper Meuse roughly marked the western border of

270-675: The 2021 European floods . The name Meuse is derived from the French name of the river, derived from its Latin name, Mosa , which ultimately derives from the Celtic or Proto-Celtic name * Mosā . This probably derives from the same root as English " maze ", referring to the river's twists and turns. The Dutch name Maas descends from Middle Dutch Mase , which comes from the presumed but unattested Old Dutch form * Masa , from Proto-Germanic * Masō . Modern Dutch and German Maas and Limburgish Maos preserve this Germanic form. Despite

300-716: The Afgedamde Maas ) so that little water from the Meuse entered the old Maas courses or the Rhine distributaries. The resulting separation of the rivers Rhine and Meuse is considered to be the greatest achievement in Dutch hydraulic engineering before the completion of the Zuiderzee Works and Delta Works . In 1970 the Haringvlietdam has been finished. Since then the reunited Rhine and Meuse waters have reached

330-653: The Holy Roman Empire with the Kingdom of France , after Count Henry III of Bar had to receive the western part of the County of Bar ( Barrois mouvant ) as a French fief from the hands of King Philip IV . In 1408, a Burgundian army led by John the Fearless went to the aid of John III against the citizens of Liège, who were in open revolt. After the battle , which saw the men from Liège defeated, John ordered

360-500: The Maas was given a new, artificial mouth – the Bergse Maas . The resulting separation of the rivers Rhine and Maas reduced the risk of flooding and was considered to be the greatest achievement in Dutch hydraulic engineering before the completion of the Zuiderzee Works and Delta Works . The former main branch was, after the dam at its southern inlet was completed in 1904, renamed Afgedamde Maas and no longer receives water from

390-742: The Maas. The Meuse and its crossings were a key objective of the Battle of France , the Battle of Sedan and also for the last major German WWII counter-offensive on the Western Front , the Battle of the Bulge in December 1944 and January 1945. The Meuse is represented in the documentary The River People released in 2012 by Xavier Istasse. In July 2021, the Meuse basin was one of the many regions in Europe to experience catastrophic flooding during

420-461: The Meuse are listed below in downstream-upstream order, with the town where the tributary meets the river: The mean annual discharge rate of the Meuse has been relatively stable over the last few thousand years. One recent study estimates that average flow has increased by about 10% since 2000 BC. The hydrological distribution of the Meuse changed during the later Middle Ages, when a major flood forced it to shift its main course northwards towards

450-494: The Meuse has the responsibility of the implementation of the treaty. The costs of this Commission are met by all these countries, in proportion of their own territory in the basin of the Meuse: Netherlands 30%, Wallonia 30%, France 15%, Germany 14.5%, Flanders 5%, Brussels 4.5%, Kingdom of Belgium 0.5%, and Luxembourg 0.5%. The map of the basin area of Meuse was joined to the text of the treaty. As for culture, as

480-562: The Meuse split near Heusden into two main distributaries, one flowing north to join the Merwede and one flowing direct to the sea. The branch of the Meuse leading direct to the sea eventually silted up (and now forms the Oude Maasje stream), but in 1904 the canalised Bergse Maas was dug to take over the functions of the silted-up branch. At the same time the branch leading to the Merwede was dammed at Heusden (and has since been known as

510-609: The Netherlands, and Belgium. Also participating in the agreement were the Belgian regional governments of Flanders , Wallonia , and Brussels (which is not in the basin of the Meuse but pumps running water into the Meuse). Most of the basin area (approximately 36,000 km ) is in Wallonia (12,000 km ), followed by France (9,000 km ), the Netherlands (8,000 km ), Germany (2,000 km ), Flanders (2,000 km ) and Luxembourg (a few km ). An International Commission on

540-474: The North Sea either at this site or, during times of lower discharges of the Rhine, at Hook of Holland . A 2008 study notes that the difference between summer and winter flow volumes has increased significantly in the last 100–200 years. It points out that the frequency of serious floods ( i.e. flows > 1000% of normal) has increased markedly. They predict that winter flooding of the Meuse may become

570-408: The border with Luxembourg . After the confluence of the two Ourthes at Lake Nisramont , the Ourthe flows roughly in north-west and later in northern direction. Near Noiseux it flows for a short distance through the province of Namur . After the municipality of Durbuy it flows into Liège Province . Eventually it flows into the river Meuse in the city of Liège . The most important tributaries of

600-471: The creation of the Biesbosch wetlands and Hollands Diep estuaries. Thereafter, the Maas split near Heusden into two main distributaries, one flowing north to join the Merwede, and one flowing directly to the sea. This latter branch is the current Oude Maasje. The branch eventually silted up, and in 1904 a new parallel channel was dug in the drainage basin , the Bergse Maas . This channel then took over

630-649: The drowning in the Meuse of burghers and noblemen in Liège whose loyalties he suspected. The border remained relatively stable until the annexation of the Three Bishoprics Metz, Toul and Verdun by King Henry II in 1552 and the occupation of the Duchy of Lorraine by the forces of King Louis XIII in 1633. Its lower Belgian ( Walloon ) portion, part of the sillon industriel , was the first fully industrialized area in continental Europe. The Afgedamde Maas

660-570: The extensive Rhine–Meuse–Scheldt delta , together with the Scheldt to its south and the Rhine to the north. The river has been divided near Heusden into the Afgedamde Maas on the right and the Bergse Maas on the left. The Bergse Maas continues under the name of Amer , which is part of De Biesbosch . The Afgedamde Maas joins the Waal, the main stem of the Rhine at Woudrichem , and then flows under

690-459: The functions of the silted-up branch, which has since been known as the Oude Maasje. At the same time, the branch leading to the Merwede was dammed at Heusden, (and has since been known as the Afgedamde Maas ) so that the vast majority of water from the Maas now enters the old Hollands Diep estuary, rather than mixing with the Rhine distributaries. Like many old river beds in the Netherlands,

720-672: The name of Boven Merwede to Hardinxveld-Giessendam , where it splits into Nieuwe Merwede and Beneden Merwede . Near Lage Zwaluwe , the Nieuwe Merwede joins the Amer, forming the Hollands Diep , which splits into Grevelingen and Haringvliet , before finally flowing into the North Sea. The Meuse is crossed by railway bridges between the following stations (on the left and right banks respectively): There are also numerous road bridges and around 32 ferry crossings. The Meuse

750-483: The river Merwede . From then on several stretches of the original Merwede were renamed "Maas" (i.e. Meuse) and served as the primary outflow of that river. Those branches are currently known as the Nieuwe Maas and Oude Maas. However during another series of severe floods the Meuse found an additional path towards the sea, resulting in the creation of the Biesbosch wetlands and Hollands Diep estuaries. Thereafter

780-615: The river Ourthe are the Amblève and the Vesdre . Towns along the Ourthe are Houffalize (Ourthe Orientale), La Roche-en-Ardenne , Hotton , Durbuy , Hamoir and Esneux . Near Hotton , the caves of Hotton are located. In these caves runs a subterranean river which flows in the Ourthe. Near Esneux lies the Roche aux Faucons. This is a vantage point located on a high cliff, above

810-540: The river can only carry more modest vessels, although a barge as long as 100 m (328 ft). can still reach the French border town of Givet. From Givet, the river is canalized over a distance of 272 kilometres (169 mi). The canalized Meuse used to be called the "Canal de l'Est — Branche Nord" but was recently rebaptized into "Canal de la Meuse". The waterway can be used by the smallest barges that are still in use commercially almost 40 m (131 ft) long and just over 5 metres (16 ft) wide. Just upstream of

840-701: The similarity, the Germanic name is not derived from the Celtic name, judging from the change from earlier o into a , which is characteristic of the Germanic languages. The Meuse rises in Pouilly-en-Bassigny, commune of Le Châtelet-sur-Meuse on the Langres plateau in France from where it flows northwards past Sedan (the head of navigation ) and Charleville-Mézières into Belgium. At Namur it

870-563: The town of Commercy, the Canal de la Meuse connects with the Marne–Rhine Canal by means of a short diversion canal. The Cretaceous sea reptile Mosasaur is named after the river Meuse. The first fossils of it were discovered outside Maastricht in 1780. An international agreement was signed in 2002 in Ghent , Belgium, about the management of the river amongst France, Germany, Luxembourg ,

900-417: Was created in the late Middle Ages, when a major flood made a connection between the Maas and the Merwede at the town of Woudrichem . From that moment on, the current Afgedamde Maas was the main branch of the lower Meuse. The former main branch eventually silted up and is today called the Oude Maasje . In the late 19th century and early 20th century the connection between the Maas and Rhine was closed off and
