38-947: The river's source is the Rhône Glacier , at the east edge of the Swiss canton of Valais . The glacier is part of the Saint-Gotthard Massif , which gives rise to three other major rivers: the Reuss , Rhine and Ticino . The Rhône is, with the Po and the Nile , one of the three Mediterranean rivers with the largest water discharge . The name Rhône continues the Latin Rhodanus name ( Greek Ῥοδανός Rhodanós ) in Greco-Roman geography . The Gaulish name of

76-526: A stub . You can help Misplaced Pages by expanding it . Marne (river) The Marne ( French pronunciation: [maʁn] ) is a river in France , an eastern tributary of the Seine in the area east and southeast of Paris . It is 514 kilometres (319 mi) long. The river gave its name to the departments of Haute-Marne , Marne , Seine-et-Marne , and Val-de-Marne . The Marne starts in

114-461: A 149 km (93 mi) section of the Rhône was made navigable for small ships up to Seyssel . As of 2017, the part between Lyon and Sault-Brénaz is closed for navigation. The Saône, which is also canalized, connects the Rhône ports to the cities of Villefranche-sur-Saône , Mâcon and Chalon-sur-Saône . Smaller vessels (up to CEMT class I ) can travel further northwest, north and northeast via

152-498: A huge toothed "claw"wheel 6.5 metres (21 ft) across to grip the river bed in the shallows to supplement the paddle wheels. In the 20th century, powerful motor barges propelled by diesel engines were introduced, carrying 1,500 tonnes (3,300,000 lb). In 1933, the Compagnie Nationale du Rhône (CNR) was established to improve navigation and generate electricity, also to develop irrigated agriculture and to protect

190-595: A series of dams and diversion canals, with a navigation lock beside the hydroelectric power plant on each of these canals. The locks were up to 23 metres (75 ft) deep. After building the Génissiat dam on the Upper Rhône (with no lock) in 1948, designed to meet the electricity needs of Paris, twelve hydroelectric plants and locks were built between 1964 and 1980. With a total head of 162 m (531 ft), they produce 13 GWh of electricity annually, or 16% of

228-450: A track of naked stone. For several years, UV-resistant fleecy white blankets have been installed during the warm periods, covering about 5 acres of the retreating glacier to reduce its melting. It's estimated that this effort reduces the melting by up to 70%. In addition to the global implications of increasing climate warming and instability, the local economy is at risk of losing business income from glacier tourists who have flocked to

266-582: Is 251 cubic metres per second (8,900 cu ft/s). Below the dam, the Rhône receives the waters of the Arve , fed by the Mont Blanc massif, with a visibly higher sediment load and much lower temperature. After a total of 290 kilometres (180 mi) in Switzerland, the Rhône continues west, entering France and the southern Jura Mountains . It turns toward the south, past Lac de Bourget , which

304-620: Is a glacier in the Swiss Alps and the source of the river Rhône and one of the primary contributors to Lake Geneva in the far eastern end of the Swiss canton of Valais . Because the glacier is located close to the Furka Pass road it is easily accessible. The Rhône Glacier is the largest glacier in the Urner Alps . It lies on the south side of the range at the source of the Rhône. The Undri Triftlimi (3,081 m) connects it to

342-824: The Centre -Loire-Briare and Loing Canals to the Seine , via the Canal de la Marne à la Saône (recently often called the " Canal entre Champagne et Bourgogne ") to the Marne , via the Canal des Vosges (formerly called the "Canal de l'Est – Branche Sud") to the Moselle and via the Canal du Rhône au Rhin to the Rhine . The Rhône is infamous for its strong current when the river carries large quantities of water: current speeds up to 10 km/h (6.2 mph) are sometimes reached, particularly in

380-867: The Langres plateau, runs generally north then bends west between Saint-Dizier and Châlons-en-Champagne , joining the Seine at Charenton just upstream from Paris. Its main tributaries are the Rognon , the Blaise , the Saulx , the Ourcq , the Petit Morin and the Grand Morin . Near the town of Saint-Dizier , part of the flow is diverted through the artificial Lake Der-Chantecoq . This ensures both flood prevention and

418-813: The Swiss Alps , at an altitude of approximately 2,208 metres (7,244 ft). From there it flows southwest through Gletsch and the Goms, the uppermost valley region of the Valais before Brig . In the Brig area, it receives the waters of the Massa from the Aletsch Glacier , the longest glacier of the Alps, and shortly after, it receives the waters of the Vispa , the longest affluent in Valais. After that, it flows onward through

456-590: The Trift Glacier . The glacier is located on the northernmost part of the canton of Valais, between the Grimsel Pass and the Furka Pass and is part of the Oberwald municipality. The Dammastock (3,630 m) is the highest summit above the glacier. The Rhône Glacier is easily accessible so its evolution is observed since the 19th century. The glacier lost ~1300 m during the last 120 years leaving behind

494-712: The Alps. From Lyon, the Rhône flows south, in its large valley between the Alps and the Massif Central . At Arles , the Rhône divides into two major arms forming the Camargue delta , both branches flowing into the Mediterranean Sea, the delta being termed the Rhône Fan. The larger arm is called the "Grand Rhône", the smaller the "Petit Rhône". The average annual discharge at Beaucaire is 1,700 m/s (60,000 cu ft/s). The main tributaries of

532-720: The Marne (September 1914), the military governor of Paris, General Joseph Gallieni , took the initiative in driving the Germans back from the capital, rendering their war-plan inoperative. In the Second Battle of the Marne (July-August 1918), the last major German offensive on the Western Front was defeated by an Allied counter-attack, leading eventually to the Armistice . During the heyday of canal transportation,

570-605: The Marne was a major artery connecting Paris and the Seine with major rivers to the east: the Meuse (via the Canal de l'Aisne à la Marne and the Canal des Ardennes ), the Moselle and the Rhine (via the Marne-Rhine Canal ), and the Saône and Rhône (via the Canal de la Marne à la Saône ). To facilitate transportation along the Marne itself, a number of lateral canals were constructed alongside. The most extensive

608-844: The Morge and Hermance, the lake is divided by the two countries along its centreline, with the left bank in France. The remainder of the lake is Swiss, including the entire right (north) bank. Here, the tributaries are the Veveyse , the Venoge , the Aubonne , the Morges , among other smaller rivers. Lake Geneva ends in the city of Geneva , where the lake level is controlled by the Le Seujet dam  [ fr ] . The average discharge from Lake Geneva

646-650: The Rhône are, from source to mouth: The Rhône has been an important highway since the times of the Greeks and Romans . It was the main trade route from the Mediterranean to east-central Gaul . As such, it helped convey Greek cultural influences to the western Hallstatt and the later La Tène cultures. Celtic tribes living near the Rhône included the Seduni , Sequani, Segobriges , Allobroges , Segusiavi , Helvetii , Vocontii and Volcae Arecomici . Navigation

684-572: The Rhône drains via the Canal de Savières . Continuing generally westward, the Rhône then receives the waters of the Valserine , enters the reservoir created by the Génissiat Dam , and is then joined by the Ain . Reaching Lyon , the most populous city on its course, the Rhône receives its biggest tributary, the Saône , with an average flow of 473 m/s (16,700 cu ft/s), compared to

722-597: The Rhône's 600 m/s (21,000 cu ft/s) at this point. From this confluence, the Rhône follows a southward course. Along the Rhône Valley, it is joined on the right (western) bank by the rivers Eyrieux , Ardèche , Cèze , and Gardon coming from the Cévennes mountains ; and on the left bank by the rivers Isère , (with an average discharge of 333 m/s (11,800 cu ft/s)), Drôme , Ouvèze , and Durance (188 m/s (6,600 cu ft/s)) from

760-542: The adjective derived from the river is rhodanien , as in le sillon rhodanien (literally "the furrow of the Rhône"), which is the name of the long, straight Saône and Rhône river valleys, a deep cleft running due south to the Mediterranean and separating the Alps from the Massif Central . Before railroads and highways were developed, the Rhône was an important inland trade and transportation route, connecting

798-452: The area since 1870 to walk through "a long and winding ice grotto with glistening blue walls and a leaky ceiling". In 2018, photographers Simon Norfolk and Klaus Thymann created a series of photographs titled "Shroud" displaying the wrapped glacier for the charity organisation Project Pressure to draw attention to the glacial retreat. This article about a glacier in Valais is

836-442: The cities of Arles , Avignon , Valence , Vienne and Lyon to the Mediterranean ports of Fos-sur-Mer , Marseille and Sète . Travelling down the Rhône by barge would take three weeks. By motorized vessel, the trip now takes only three days. The Rhône is classified as a Class V waterway for the 325 km-long (202-mile) section from the mouth of the Saône at Lyon to the sea at Port-Saint-Louis-du-Rhône . Upstream from Lyon,

874-521: The country's total hydroelectric production (20% if the Upper Rhône schemes are added). There have been significant benefits for agriculture throughout the Rhône valley. With the Lower Rhône project completed, CNR turned its attention to the Haut-Rhône (Upper Rhône), and built four hydropower dams in the 1980s: Sault-Brénaz, Brégnier-Cordon, Belley-Brens and Chautagne. It also drew up plans for

912-583: The high-capacity Rhine-Rhône Waterway, along the route of the existing Canal du Rhône au Rhin , but this project was abandoned in 1997. In the period from 2005 to 2010, navigation locks of small barge dimensions (40 by 6 m) were built to bypass the last two, forming a navigable waterway network with Lake Bourget, through the Canal de Savières . Cities and towns along the Rhône include: Rh%C3%B4ne Glacier The Rhône Glacier ( German : Rhonegletscher , Walliser German : Rottengletscher , French : glacier du Rhône , Italian : ghiacciaio del Rodano )

950-633: The historical region of Chablais . It then enters Lake Geneva near Le Bouveret , where the water flows west. On the left (south) bank of Lake Geneva, the river Morge joins at the village of Saint-Gingolph , and also marks the French-Swiss border. Westward, the Dranse (unrelated to the Drance) enters the lake with its preserved delta , and then the Hermance marks another French-Swiss border. Between

988-492: The large glaciers of the massifs of Monte Rosa , Dom , and Grand Combin , but also from the steeper slopes of the Bernese Alps to the north, and the Mont Blanc massif to the west. As a result, the Rhône Valley experiences a drier climate than the rest of Switzerland , being sheltered by the three highest ranges of the Alps, making Valais the driest and largest wine region of the country. At Martigny, where it receives

1026-409: The maintenance of minimum river flows in periods of drought. The Marne is famous as the site of two eponymous battles during World War I . The first battle was a turning point of the war, fought in 1914. The second battle was fought four years later, in 1918. The Celts of Gaul worshipped a goddess known as Dea Matrona ("divine mother goddess") who was associated with the Marne. The Marne

1064-672: The reconstructed Gaulish name is masculine, as is French le Rhône . This form survives in the Spanish/Portuguese and Italian namesakes, el/o Ródano and il Rodano , respectively. German has adopted the French name but given it the feminine gender, die Rhone . The original German adoption of the Latin name was also masculine, der Rotten ; it survives only in the Upper Valais ( dialectal Rottu ). In French,

1102-448: The river was * Rodonos or * Rotonos (from a PIE root * ret- "to run, roll" frequently found in river names). Names in other languages include German : Rhone [ˈroːnə] ; Walser : Rotten [ˈrotən] ; Italian : Rodano [ˈrɔːdano] ; Arpitan : Rôno [ˈʁono] ; Occitan : Ròse [ˈrɔze, ˈʀɔze] ; and Romansh : Rodan . The Greco-Roman as well as

1140-508: The riverside towns and land from flooding. Some progress was made in deepening the navigation channel and constructing scouring walls, but World War II brought such work to a halt. In 1942, following the collapse of Vichy France , Italian military forces occupied southeastern France up to the eastern banks of the Rhône, as part of the Italian Fascist regime's expansionist agenda. In 1948, the French government started construction of

1178-415: The stretch below the last lock at Vallabrègues and in the relatively narrow first diversion canal south of Lyon. The 12 locks are operated daily from 5:00 a.m. until 9:00 p.m. All operation is centrally controlled from one control centre at Châteauneuf. Commercial barges may navigate during the night hours by authorisation. The Rhône begins as the meltwater of the Rhône Glacier in Valais , in

1216-412: The upper river used barques du Rhône , sailing barges, 30 by 3.5 metres (98 by 11 ft), with a 75-tonne (165,000 lb) capacity. As many as 50 to 80 horses were employed to haul trains of five to seven craft upstream. Goods would be transshipped at Arles into 23-metre (75 ft) sailing barges called allèges d'Arles for the final run down to the Mediterranean. The first experimental steam boat

1254-490: The valley which bears its name and runs initially in a westerly direction about thirty kilometers to Leuk , then southwest about fifty kilometers to Martigny . Down as far as Brig , the Rhône is a torrent; it then becomes a great mountain river running southwest through a glacial valley. Between Brig and Martigny , it collects waters mostly from the valleys of the Pennine Alps to the south, whose rivers originate from

1292-526: The waters of the Drance on its left bank, the Rhône makes a sharp turn towards the north. Heading toward Lake Geneva ( French : Le Léman ), the valley narrows near Saint-Maurice , a feature that has long given the Rhône valley strategic importance for the control of the Alpine passes. The Rhône then marks the boundary between the cantons of Valais (left bank) and Vaud (right bank), separating two parts of

1330-433: Was built at Lyon by Jouffroy d'Abbans in 1783. Regular services were not started until 1829 and they continued until 1952. Steam passenger vessels 80 to 100 metres (260–330 ft) long made up to 20 km/h (11 kn) and could do the downstream run from Lyon to Arles in a day. Cargo was hauled in bateau-anguilles , boats 157 by 6.35 metres (515.1 by 20.8 ft) with paddle wheels amidships, and bateaux crabes ,

1368-403: Was difficult, as the river suffered from fierce currents, shallows, floods in spring and early summer when the ice was melting, and droughts in late summer. Until the 19th century, passengers travelled in coches d'eau (water coaches) drawn by men or horses, or under sail. Most travelled with a painted cross covered with religious symbols as protection against the hazards of the journey. Trade on

1406-525: Was navigable as a free-flowing river until the 19th century. It had one gated 500 m shortcut, the Canal de Cornillon in Meaux, which was built in 1235, the oldest canal in France. Canalisation was started in 1837 and completed to Épernay in 1867. It included a number of canals to bypass the most extravagant meanders. In World War I , the Marne was the scene of two notable battles. In the First Battle of

1444-416: Was the Canal latéral à la Marne , which runs 67 km (42 mi) between Vitry-le-François and Dizy . Downstream of this were several more, including the Canal de Meaux à Chalifert , the Canal de Chelles , and the Canal de Saint-Maurice which ended at Charenton-le-Pont near the Marne's confluence with the Seine . Furthermore, a portion of the Canal de l'Ourcq also runs parallel and quite close to
