The Rhine (Latin : Rhenus, Romansh : Rein, German : Rhein, French : le Rhin, Italian : Reno, Dutch : Rijn) is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the Swiss-Liechtenstein, Swiss-Austrian, Swiss-German and then the Franco-German border, then flows through the German Rhineland and the Netherlands and eventually empties into the North Sea.
Romansh (also spelled Romansch, Rumantsch, or Romanche; Romansh:
German is a West Germanic language that is mainly spoken in Central Europe. It is the most widely spoken and official or co-official language in Germany, Austria, Switzerland, South Tyrol (Italy), the German-speaking Community of Belgium, and Liechtenstein. It is also one of the three official languages of Luxembourg and a co-official language in the Opole Voivodeship in Poland. The languages which are most similar to German are the other members of the West Germanic language branch: Afrikaans, Dutch, English, the Frisian languages, Low German/Low Saxon, Luxembourgish, and Yiddish. There are also strong similarities in vocabulary with Danish, Norwegian and Swedish, although those belong to the North Germanic group. German is the second most widely spoken Germanic language, after English.
French is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the spoken Latin in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) has largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the (Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to France's past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French.
The largest city on the Rhine is Cologne, Germany, with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe (after the Danube), at about 1,230 km (760 mi), with an average discharge of about 2,900 m3/s (100,000 cu ft/s).
Cologne is the largest city of Germany's most populous federal state of North Rhine-Westphalia, and its 1 million+ (2016) inhabitants make it the fourth most populous city in Germany after Berlin, Hamburg, and Munich. The largest city on the Rhine, it is also the most populous city both of the Rhine-Ruhr Metropolitan Region, which is Germany's largest and one of Europe's major metropolitan areas, and of the Rhineland. Centred on the left bank of the Rhine, Cologne is about 45 kilometres (28 mi) southeast of North Rhine-Westphalia's capital of Düsseldorf and 25 kilometres (16 mi) northwest of Bonn. It is the largest city in the Central Franconian and Ripuarian dialect areas.
The Danube, known by various names in other languages, is Europe's second longest river, after the Volga. It is located in Central and Eastern Europe.
The Rhine and the Danube formed most of the northern inland frontier of the Roman Empire and, since those days, the Rhine has been a vital and navigable waterway carrying trade and goods deep inland. Its importance as a waterway in the Holy Roman Empire is supported by the many castles and fortifications built along it. In the modern era, it has become a symbol of German nationalism.
The Limes Germanicus was a line of frontier (limes) fortifications that bounded the ancient Roman provinces of Germania Inferior, Germania Superior and Raetia, dividing the Roman Empire and the unsubdued Germanic tribes from the years 83 to about 260 AD. At its height, the limes stretched from the North Sea outlet of the Rhine to near Regensburg on the Danube. Those two major rivers afforded natural protection from mass incursions into imperial territory, with the exception of a gap stretching roughly from Mogontiacum (Mainz) on the Rhine to Castra Regina.
The Roman Empire was the post-Roman Republic period of the ancient Roman civilization. It had a government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, North Africa, and West Asia. From the constitutional reforms of Augustus to the military anarchy of the third century, the Empire was a principate ruled from the city of Rome. The Roman Empire was then divided between a Western Roman Empire, based in Milan and later Ravenna, and an Eastern Roman Empire, based in Nicomedia and later Constantinople, and it was ruled by multiple emperors.
The Holy Roman Empire was a multi-ethnic complex of territories in Western and Central Europe that developed during the Early Middle Ages and continued until its dissolution in 1806 during the Napoleonic Wars. The largest territory of the empire after 962 was the Kingdom of Germany, though it also came to include the neighboring Kingdom of Bohemia, the Kingdom of Burgundy, the Kingdom of Italy, and numerous other territories.
The variants of the name of the Rhine in modern languages are all derived from the Gaulish name Rēnos, which was adapted in Roman-era geography (1st century BC) as Greek Ῥῆνος (Rhēnos), Latin Rhenus.
Gaulish was an ancient Celtic language that was spoken in parts of Europe before and during the period of the Roman Empire. In the narrow sense, Gaulish was the language spoken by the Celtic inhabitants of Gaul. In a wider sense, it also comprises varieties of Celtic that were spoken across much of central Europe ("Noric"), parts of the Balkans, and Asia Minor ("Galatian"), which are thought to have been closely related. The more divergent Lepontic of Northern Italy has also sometimes been subsumed under Gaulish.
The spelling with Rh- in English Rhine as well as in German Rhein and French Rhin is due to the influence of Greek orthography, while the vocalisation -i- is due to the Proto-Germanic adoption of the Gaulish name as * Rīnaz , via Old Frankish giving Old English Rín,Old High German Rīn, early Middle Dutch (c. 1200) Rijn (then also spelled Ryn or Rin).
Old English, or Anglo-Saxon, is the earliest historical form of the English language, spoken in England and southern and eastern Scotland in the early Middle Ages. It was brought to Great Britain by Anglo-Saxon settlers probably in the mid-5th century, and the first Old English literary works date from the mid-7th century. After the Norman conquest of 1066, English was replaced, for a time, as the language of the upper classes by Anglo-Norman, a relative of French. This is regarded as marking the end of the Old English era, as during this period the English language was heavily influenced by Anglo-Norman, developing into a phase known now as Middle English.
Old High German is the earliest stage of the German language, conventionally covering the period from around 700 to 1050. Coherent written texts do not appear until the second half of the 8th century, and some treat the period before 750 as "prehistoric" and date the start of Old High German proper to 750 for this reason. There are, however, a number of Elder Futhark inscriptions dating to the 6th century, as well as single words and many names found in Latin texts predating the 8th century.
Middle Dutch is a collective name for a number of closely related West Germanic dialects whose ancestor was Old Dutch and was spoken and written between 1150 and 1500. Until the advent of Modern Dutch after 1500, there was no overarching standard language, but all dialects were mutually intelligible. During the period, a rich Medieval Dutch literature developed, which had not yet existed during Old Dutch. The various literary works of the time are often very readable for speakers of Modern Dutch since Dutch is a rather conservative language. Nonlinguists often refer to Middle Dutch as Diets.
The diphthong in modern German Rhein (also adopted in Romansh Rein, Rain) is a Central German development of the early modern period, the Alemannic name Rī(n) retaining the older vocalism,as does Ripuarian Rhing, while Palatine has diphthongized Rhei, Rhoi. Spanish is with French in adopting the Germanic vocalism Rin-, while Italian, Occitan and Portuguese retain the Latin Ren-.
Central German is a group of High German dialects spoken from the Rhineland in the west to the former eastern territories of Germany.
Early New High German (ENHG) is a term for the period in the history of the German language, generally defined, following Wilhelm Scherer, as the period 1350 to 1650.
Alemannic, or rarely Alemmanish, is a group of dialects of the Upper German branch of the Germanic language family. The name derives from the ancient Germanic alliance of tribes known as the Alemanni.
The Gaulish name Rēnos (Proto-Celtic or pre-Celtic *rei- "to move, flow, run", also found in other names such as the Reno in Italy.*Reinos) belongs to a class of river names built from the PIE root
The grammatical gender of the Celtic name (as well as of its Greek and Latin adaptation) is masculine, and the name remains masculine in German, Dutch and French. The Old English river name was variously inflected as masculine or feminine; and its Old Icelandic adoption was inflected as feminine.
The length of the Rhine is conventionally measured in "Rhine-kilometers" (Rheinkilometer), a scale introduced in 1939 which runs from the Old Rhine Bridge at Constance (0 km) to Hoek van Holland (1036.20 km).
The river is significantly shortened from its natural course due to a number of canalisation projects completed in the 19th and 20th century. 1,232 kilometres (766 miles) by the Dutch Rijkswaterstaat in 2010.The "total length of the Rhine", to the inclusion of Lake Constance and the Alpine Rhine is more difficult to measure objectively; it was cited as

The Rhine carries its name without distinctive accessories only from the confluence of the Rein Anteriur/Vorderrhein and Rein Posteriur/Hinterrhein next to Reichenau in Tamins. Above this point is the extensive catchment of the headwaters of the Rhine. It belongs almost exclusively to the Swiss canton of Graubünden, ranging from Saint-Gotthard Massif in the west via one valley lying in Ticino and Italy in the south to the Flüela Pass in the east.
Traditionally, Lake Toma near the Oberalp Pass in the Gotthard region is seen as the source of the Anterior Rhine and the Rhine as a whole. The Posterior Rhine rises in the Rheinwald below the Rheinwaldhorn.
The source of the river is generally considered north of Lai da Tuma/Tomasee on Rein Anteriur/Vorderrhein,although its southern tributary Rein da Medel is actually longer before its confluence with the Anterior Rhine near Disentis.
The Anterior Rhine arises from numerous source streams in the upper Surselva and flows in an easterly direction. One source is Lai da Tuma (2,345 m (7,694 ft)) with the Rein da Tuma , which is usually indicated as source of the Rhine, flowing through it.
Into it flow tributaries from the south, some longer, some equal in length, such as the Rein da Medel, the Rein da Maighels , and the Rein da Curnera . The Cadlimo Valley in the canton of Ticino is drained by the Reno di Medel, which crosses the geomorphologic Alpine main ridge from the south.All streams in the source area are partially, sometimes completely, captured and sent to storage reservoirs for the local hydro-electric power plants.
The culminating point of the Anterior Rhine's drainage basin is the Piz Russein of the Tödi massif of the Glarus Alps at 3,613 metres (11,854 ft) above sea level. It starts with the creek Aua da Russein (lit.: "Water of the Russein").
In its lower course the Anterior Rhine flows through a gorge named Ruinaulta (Flims Rockslide). The whole stretch of the Anterior Rhine to the Alpine Rhine confluence next to Reichenau in Tamins is accompanied by a long-distance hiking trail called Senda Sursilvana.
The Posterior Rhine flows first east-northeast, then north. It flows through the three valleys named Rheinwald, Schams and Domleschg-Heinzenberg. The valleys are separated by the Rofla Gorge and Viamala Gorge. Its sources are located in the Adula Alps (Rheinwaldhorn, Rheinquellhorn, and Güferhorn).
The Avers Rhine joins from the south. One of its headwaters, the Reno di Lei (stowed in the Lago di Lei), is partially located in Italy.
Near Sils the Posterior Rhine is joined by the Albula, from the east, from the Albula Pass region. The Albula draws its water mainly from the Landwasser with the Dischmabach as the largest source stream, but almost as much from the Gelgia, which comes down from the Julier Pass.
Numerous larger and smaller tributary rivers bear the name of the Rhine or equivalent in various Romansh idioms like Rein or Ragn. Examples:
Next to Reichenau in Tamins the Anterior Rhine and the Posterior Rhine join and form the Alpine Rhine. The river makes a distinctive turn to the north near Chur. This section is nearly 86 km long, and descends from a height of 599 m to 396 m. It flows through a wide glacial Alpine valley known as the Rhine Valley (German : Rheintal). Near Sargans a natural dam, only a few metres high, prevents it from flowing into the open Seeztal valley and then through Lake Walen and Lake Zurich into the Aare. The Alpine Rhine begins in the westernmost part of the Swiss canton of Graubünden, and later forms the border between Switzerland to the west and Liechtenstein and later Austria to the east.
As an effect of human work, it empties into Lake Constance on Austrian territory and not on the border that follows its old natural river bed.
The mouth of the Rhine into Lake Constance forms an inland delta. The delta is delimited in the west by the Alter Rhein ("Old Rhine") and in the east by a modern canalized section. Most of the delta is a nature reserve and bird sanctuary. It includes the Austrian towns of Gaißau, Höchst and Fußach. The natural Rhine originally branched into at least two arms and formed small islands by precipitating sediments. In the local Alemannic dialect, the singular is pronounced "Isel" and this is also the local pronunciation of Esel ("Donkey"). Many local fields have an official name containing this element.
A regulation of the Rhine was called for, with an upper canal near Diepoldsau and a lower canal at Fußach, in order to counteract the constant flooding and strong sedimentation in the western Rhine Delta. The Dornbirner Ach had to be diverted, too, and it now flows parallel to the canalized Rhine into the lake. Its water has a darker color than the Rhine; the latter's lighter suspended load comes from higher up the mountains. It is expected that the continuous input of sediment into the lake will silt up the lake. This has already happened to the former Lake Tuggenersee.
The cut-off Old Rhine at first formed a swamp landscape. Later an artificial ditch of about two km was dug. It was made navigable to the Swiss town of Rheineck.
Lake Constance consists of three bodies of water: the Obersee ("upper lake"), the Untersee ("lower lake"), and a connecting stretch of the Rhine, called the Seerhein ("Lake Rhine"). The lake is situated in Germany, Switzerland and Austria near the Alps. Specifically, its shorelines lie in the German states of Bavaria and Baden-Württemberg, the Austrian state of Vorarlberg, and the Swiss cantons of Thurgau and St. Gallen. The Rhine flows into it from the south following the Swiss-Austrian border. It is located at approximately.
The flow of cold, grey mountain water continues for some distance into the lake. The cold water flows near the surface and at first doesn't mix with the warmer, green waters of Upper Lake. But then, at the so-called Rheinbrech, the Rhine water abruptly falls into the depths because of the greater density of cold water. The flow reappears on the surface at the northern (German) shore of the lake, off the island of Lindau. The water then follows the northern shore until Hagnau am Bodensee. A small fraction of the flow is diverted off the island of Mainau into Lake Überlingen. Most of the water flows via the Constance hopper into the Rheinrinne ("Rhine Gutter") and Seerhein. Depending on the water level, this flow of the Rhine water is clearly visible along the entire length of the lake.
The Rhine carries very large amounts of debris into the lake.In the mouth region, it is therefore necessary to permanently remove gravel by dredging. The large sediment loads are partly due to the extensive land improvements upstream.
Three countries border the Obersee, namely Switzerland in the south, Austria in the southeast and the German states of Bavaria in the northeast and Baden-Württemberg in the north and northwest.
The Seerhein is only four km long. It connects the Obersee with the 30 cm lower Untersee. Distance markers along the Rhine measure the distance from the bridge in the old city centre of Constance.
For most of its length, the Seerhein forms the border between Germany and Switzerland. The exception is the old city centre of Constance, on the Swiss side of the river.
The Seerhein emerged in the last thousands of years, when erosion caused the lake level to be lowered by about 10 metres. Previously, the two lakes formed a single lake, as the name still suggests.
Like in the Obersee, the flow the Rhine can be traced in the Untersee. Here, too, the river water is hardly mixed with the lake water. The northern parts of the Untersee (Lake Zell and Gnadensee) remain virtually unaffected by the flow. The river traverses the southern, which, in isolation, is sometimes called Rhinesee ("Lake Rhine").
The Radolfzeller Aach adds large amounts of water from the Danube system to the Untersee.
Reichenau Island was formed at the same time as the Seerhein, when the water level was lowered to its current level.
Lake Untersee is part of the border between Switzerland and Germany, with Germany on the north bank and Switzerland on the south, except both sides are Swiss in Stein am Rhein, where the High Rhine flows out of the lake.
The Rhine emerges from Lake Constance, flows generally westward, as the Hochrhein, passes the Rhine Falls, and is joined by its major tributary, the Aare. The Aare more than doubles the Rhine's water discharge, to an average of nearly 1,000 m3/s (35,000 cu ft/s), and provides more than a fifth of the discharge at the Dutch border. The Aare also contains the waters from the 4,274 m (14,022 ft) summit of Finsteraarhorn, the highest point of the Rhine basin. The Rhine roughly forms the German-Swiss border from Lake Constance with the exceptions of the canton of Schaffhausen and parts of the cantons of Zürich and Basel-Stadt, until it turns north at the so-called Rhine knee at Basel, leaving Switzerland.
The High Rhine begins in Stein am Rhein at the western end of the Untersee. Unlike the Alpine Rhine and Upper Rhine, it flows to the west. It falls from 395 m to 252 m. Some stretches of the High Rhine between Stein am Rhein and Eglisau form the border between Switzerland on the south bank and Germany in the north. On other stretches, both sides are Swiss; in fact most of the Canton of Schaffhausen is on the north bank. Between Eglisau and Basel, the High Rhine consistently forms the border.
The Rhine Falls are situated below Schaffhausen. It has an average water flow of 373 m³/s (mean summer discharge 700 m³/s) and is the second largest waterfall in Europe in terms of potential energy, after Dettifoss in Iceland. The High Rhine is characterized by numerous dams. On the few remaining natural sections, there are still several rapids.
Near Koblenz in the Aargau, the Aare joins the Rhine. With an average discharge of 557 m³/s, the Aare is more voluminous than the Rhine, which has an average discharge of 439 m³/s. Nevertheless, the Alpine Rhine is considered the main branch, because it is longer.
In the centre of Basel, the first major city in the course of the stream, is located the "Rhine knee"; this is a major bend, where the overall direction of the Rhine changes from west to north. Here the High Rhine ends. Legally, the Central Bridge is the boundary between High and Upper Rhine. The river now flows north as Upper Rhine through the Upper Rhine Plain, which is about 300 km long and up to 40 km wide. The most important tributaries in this area are the Ill below of Strasbourg, the Neckar in Mannheim and the Main across from Mainz. In Mainz, the Rhine leaves the Upper Rhine Valley and flows through the Mainz Basin.
The southern half of the Upper Rhine forms the border between France (Alsace) and Germany (Baden-Württemberg). The northern part forms the border between the German states of Rhineland-Palatinate in the west on the one hand, and Baden-Württemberg and Hesse on the other hand, in the east and north. A curiosity of this border line is that the parts of the city of Mainz on the right bank of the Rhine were given to Hesse by the occupying forces in 1945.
The Upper Rhine was a significant cultural landscape in Central Europe already in antiquity and during the Middle Ages. Today, the Upper Rhine area hosts many important manufacturing and service industries, particularly in the centers Basel, Strasbourg and Mannheim-Ludwigshafen. Strasbourg is the seat of the European Parliament, and so one of the three European capitals is located on the Upper Rhine.
The Upper Rhine region was changed significantly by a Rhine straightening program in the 19th Century. The rate of flow was increased and the ground water level fell significantly. Dead branches were removed by construction workers and the area around the river was made more habitable for humansflood plains as flooding decreased sharply. On the French side, the Grand Canal d'Alsace was dug, which carries a significant part of the river water, and all of the traffic. In some places, there are large compensation pools, for example, the huge Bassin de compensation de Plobsheim in Alsace.
The Upper Rhine has undergone significant human change since the 19th century. While it was slightly modified during the Roman occupation, it was not until the emergence of engineers such as Johann Gottfried Tulla that significant modernization efforts changed the shape of the river. Earlier work under Frederick the Great surrounded efforts to ease shipping and construct dams to serve coal transportation.Tulla is considered to have domesticated the Upper Rhine, domestication that served goals such as reducing stagnant bogs that fostered waterborne diseases, making regions more habitable for human settlement, and reduce high frequency of flooded water. Not long before Tulla went to work on widening and straightening the river heavy floods had brought significant loss of life. Four diplomatic treaties were signed among German state governments and French regions dealing with the changes proposed along the Rhine, one was "the Treaty for the Rectification of the Rhine flow from Neuberg to Dettenheim"(1817), which surrounded states such as Bourbon France and the Bavarian Palatinate. Loops, oxbows, branches and islands were removed along the Upper Rhine so that there would be a present uniformity to the river. The engineering of the Rhine was not without protest, farmers and fishermen had grave concerns about valuable fishing areas and farmland being lost. While some areas lost ground, other areas saw swamps and bogs be drained and turned into arable land. Johann Tulla had the goal of shortening and straightening the Upper Rhine. Early engineering projects the Upper Rhine also had issues, with Tulla's project at one part of the river creating rapids, after the Rhine cut down from erosion to sheer rock. Engineering along the Rhine eased flooding and made transportation along the river less cumbersome. These state projects were part of the advanced and technical progress efforts going on in the country alongside the industrial revolution. For the German state, to make the river more predictable was to ensure development projects could easily commence.
The section of the Upper Rhine downstream from Mainz is also known as the "Island Rhine". Here a number of river islands occur, locally known as "Rheinauen".
The Rhine is the longest river in Germany. It is here that the Rhine encounters some more of its main tributaries, such as the Neckar, the Main and, later, the Moselle, which contributes an average discharge of more than 300 m3/s (11,000 cu ft/s). Northeastern France drains to the Rhine via the Moselle; smaller rivers drain the Vosges and Jura Mountains uplands. Most of Luxembourg and a very small part of Belgium also drain to the Rhine via the Moselle. As it approaches the Dutch border, the Rhine has an annual mean discharge of 2,290 m3/s (81,000 cu ft/s) and an average width of 400 m (1,300 ft).
Between Bingen am Rhein and Bonn, the Middle Rhine flows through the Rhine Gorge, a formation which was created by erosion. The rate of erosion equaled the uplift in the region, such that the river was left at about its original level while the surrounding lands raised. The gorge is quite deep and is the stretch of the river which is known for its many castles and vineyards. It is a UNESCO World Heritage Site (2002) and known as "the Romantic Rhine", with more than 40 castles and fortresses from the Middle Ages and many quaint and lovely country villages.
The Mainz Basin ends in Bingen am Rhein; the Rhine continues as "Middle Rhine" into the Rhine Gorge in the Rhenish Slate Mountains. In this sections the river falls from 77.4 m above sea level to 50.4 m. On the left, is located the mountain ranges of Hunsrück and Eifel, on the right Taunus and Westerwald. According to geologists, the characteristic narrow valley form was created by erosion by the river while the surrounding landscape was lifted (see water gap).
Major tributaries in this section are the Lahn and the Moselle. They join the Rhine near Koblenz, for the right and left respectively. Almost the entire length of the Middle Rhine runs in the German state of Rhineland-Palatinate.
The dominant economic sectors in the Middle Rhine area are viniculture and tourism. The Rhine Gorge between Rüdesheim am Rhein and Koblenz is listed as a UNESCO World Heritage Site. Near Sankt Goarshausen, the Rhine flows around the famous rock Lorelei. With its outstanding architectural monuments, the slopes full of vines, settlements crowded on the narrow river banks and scores of castles lined up along the top of the steep slopes, the Middle Rhine Valley can be considered the epitome of the Rhine romanticism.
In Bonn, where the Sieg flows into the Rhine, the Rhine enters the North German Plain and turns into the Lower Rhine. The Lower Rhine falls from 50 m to 12 m. The main tributaries on this stretch are the Ruhr and the Lippe. Like the Upper Rhine, the Lower Rhine used to meander until engineering created a solid river bed. Because the levees are some distance from the river, at high tide the Lower Rhine has more room for widening than the Upper Rhine.
The Lower Rhine flows through North Rhine-Westphalia. Its banks are usually heavily populated and industrialized, in particular the agglomerations Cologne, Düsseldorf and Ruhr area. Here the Rhine flows through the largest conurbation in Germany, the Rhine-Ruhr region. One of the most important cities in this region is Duisburg with the largest river port in Europe (Duisport). The region downstream of Duisburg is more agricultural. In Wesel, 30 km downstream of Duisburg, is located the western end of the second east-west shipping route, the Wesel-Datteln Canal, which runs parallel to the Lippe. Between Emmerich and Cleves the Emmerich Rhine Bridge, the longest suspension bridge in Germany, crosses the 400-metre-wide (1,300 ft) river. Near Krefeld, the river crosses the Uerdingen line, the line which separates the areas where Low German and High German are spoken.
Until the early 1980s, industry was a major source of water pollution. Although many plants and factories can be found along the Rhine up into Switzerland, it is along the Lower Rhine that the bulk of them are concentrated, as the river passes the major cities of Cologne, Düsseldorf and Duisburg. Duisburg is the home of Europe's largest inland port and functions as a hub to the sea ports of Rotterdam, Antwerp and Amsterdam. The Ruhr, which joins the Rhine in Duisburg, is nowadays a clean river, thanks to a combination of stricter environmental controls, a transition from heavy industry to light industry and cleanup measures, such as the reforestation of Slag and brownfields. The Ruhr currently provides the region with drinking water. It contributes 70 m3/s (2,500 cu ft/s) to the Rhine. Other rivers in the Ruhr Area, above all, the Emscher, still carry a considerable degree of pollution.
The Dutch name for Rhine is "Rijn". The Rhine turns west and enters the Netherlands, where, together with the rivers Meuse and Scheldt, it forms the extensive Rhine-Meuse-Scheldt delta, with 25,347 km2 (9,787 sq mi) the largest river delta in Europe. Crossing the border into the Netherlands at Spijk, close to Nijmegen and Arnhem, the Rhine is at its widest, although the river then splits into three main distributaries: the Waal, Nederrijn ("Nether Rhine") and IJssel.
From here, the situation becomes more complicated, as the Dutch name Rijn no longer coincides with the main flow of water. Two thirds of the water flow volume of the Rhine flows farther west, through the Waal and then, via the Merwede and Nieuwe Merwede (De Biesbosch), merging with the Meuse, through the Hollands Diep and Haringvliet estuaries, into the North Sea. The Beneden Merwede branches off, near Hardinxveld-Giessendam and continues as the Noord, to join the Lek, near the village of Kinderdijk, to form the Nieuwe Maas; then flows past Rotterdam and continues via Het Scheur and the Nieuwe Waterweg, to the North Sea. The Oude Maas branches off, near Dordrecht, farther down rejoining the Nieuwe Maas to form Het Scheur.
The other third of the water flows through the Pannerdens Kanaal and redistributes in the IJssel and Nederrijn. The IJssel branch carries one ninth of the water flow of the Rhine north into the IJsselmeer (a former bay), while the Nederrijn carries approximately two ninths of the flow west along a route parallel to the Waal. However, at Wijk bij Duurstede, the Nederrijn changes its name and becomes the Lek. It flows farther west, to rejoin the Noord into the Nieuwe Maas and to the North Sea.
The name Rijn, from here on, is used only for smaller streams farther to the north, which together formed the main river Rhine in Roman times. Though they retained the name, these streams no longer carry water from the Rhine, but are used for draining the surrounding land and polders. From Wijk bij Duurstede, the old north branch of the Rhine is called Kromme Rijn ("Bent Rhine") past Utrecht, first Leidse Rijn ("Rhine of Leiden") and then, Oude Rijn ("Old Rhine"). The latter flows west into a sluice at Katwijk, where its waters can be discharged into the North Sea. This branch once formed the line along which the Limes Germanicus were built. During periods of lower sea levels within the various ice ages, the Rhine took a left turn, creating the Channel River, the course of which now lies below the English Channel.
The Rhine-Meuse Delta, the most important natural region of the Netherlands begins near Millingen aan de Rijn, close to the Dutch-German border with the division of the Rhine into Waal and Nederrijn. Since the Rhine contributes most of the water, the shorter term Rhine Delta is commonly used. However, this name is also used for the river delta where the Rhine flows into Lake Constance, so it is clearer to call the larger one Rhine-Meuse delta, or even Rhine–Meuse–Scheldt delta , as the Scheldt ends in the same delta.
The shape of the Rhine delta is determined by two bifurcations: first, at Millingen aan de Rijn, the Rhine splits into Waal and Pannerdens Kanaal, which changes its name to Nederrijn at Angeren, and second near Arnhem, the IJssel branches off from the Nederrijn. This creates three main flows, two of which change names rather often. The largest and southern main branch begins as Waal and continues as Boven Merwede ("Upper Merwede"), Beneden Merwede ("Lower Merwede"), Noord ("the North"), Nieuwe Maas ("New Meuse"), Het Scheur ("the Rip") and Nieuwe Waterweg ("New Waterway"). The middle flow begins as Nederrijn, then changes into Lek, then joins the Noord, thereby forming Nieuwe Maas. The northern flow keeps the name IJssel until it flows into Lake IJsselmeer. Three more flows carry significant amounts of water: the Nieuwe Merwede ("New Merwede"), which branches off from the southern branch where it changes from Boven to Beneden Merwede; the Oude Maas ("Old Meuse"), which branches off from the southern branch where it changes from Beneden Merwede into Noord, and Dordtse Kil, which branches off from Oude Maas.
Before the St. Elizabeth's flood (1421), the Meuse flowed just south of today's line Merwede-Oude Maas to the North Sea and formed an archipelago-like estuary with Waal and Lek. This system of numerous bays, estuary-like extended rivers, many islands and constant changes of the coastline, is hard to imagine today. From 1421 to 1904, the Meuse and Waal merged further upstream at Gorinchem to form Merwede. For flood protection reasons, the Meuse was separated from the Waal through a lock and diverted into a new outlet called "Bergse Maas", then Amer and then flows into the former bay Hollands Diep.
The northwestern part of the estuary (around Hook of Holland), is still called Maasmond ("Meuse Mouth"), ignoring the fact that it now carries only water from the Rhine. This might explain the confusing naming of the various branches.
The hydrography of the current delta is characterized by the delta's main arms, disconnected arms (Hollandse IJssel, Linge, Vecht, etc.) and smaller rivers and streams. Many rivers have been closed ("dammed") and now serve as drainage channels for the numerous polders. The construction of Delta Works changed the Delta in the second half of the 20th Century fundamentally. Currently Rhine water runs into the sea, or into former marine bays now separated from the sea, in five places, namely at the mouths of the Nieuwe Merwede, Nieuwe Waterway (Nieuwe Maas), Dordtse Kil, Spui and IJssel.
The Rhine-Meuse Delta is a tidal delta, shaped not only by the sedimentation of the rivers, but also by tidal currents. This meant that high tide formed a serious risk because strong tidal currents could tear huge areas of land into the sea. Before the construction of the Delta Works, tidal influence was palpable up to Nijmegen, and even today, after the regulatory action of the Delta Works, the tide acts far inland. At the Waal, for example, the most landward tidal influence can be detected between Brakel and Zaltbommel.
The Rhine flows from the Alps to the North Sea Basin; the geography and geology of its present-day watershed has been developing, since the Alpine orogeny began.
In southern Europe, the stage was set in the Triassic Period of the Mesozoic Era, with the opening of the Tethys Ocean, between the Eurasian and African tectonic plates, between about 240 MBP and 220 MBP (million years before present). The present Mediterranean Sea descends from this somewhat larger Tethys sea. At about 180 MBP, in the Jurassic Period, the two plates reversed direction and began to compress the Tethys floor, causing it to be subducted under Eurasia and pushing up the edge of the latter plate in the Alpine Orogeny of the Oligocene and Miocene Periods. Several microplates were caught in the squeeze and rotated or were pushed laterally, generating the individual features of Mediterranean geography: Iberia pushed up the Pyrenees; Italy, the Alps, and Anatolia, moving west, the mountains of Greece and the islands. The compression and orogeny continue today, as shown by the ongoing raising of the mountains a small amount each year and the active volcanoes.
In northern Europe, the North Sea Basin had formed during the Triassic and Jurassic periods and continued to be a sediment receiving basin since. In between the zone of Alpine orogeny and North Sea Basin subsidence, remained highlands resulting from an earlier orogeny (Variscan), such as the Ardennes, Eifel and Vosges.
From the Eocene onwards, the ongoing Alpine orogeny caused a N–S rift system to develop in this zone. The main elements of this rift are the Upper Rhine Graben, in southwest Germany and eastern France and the Lower Rhine Embayment, in northwest Germany and the southeastern Netherlands. By the time of the Miocene, a river system had developed in the Upper Rhine Graben, that continued northward and is considered the first Rhine river. At that time, it did not yet carry discharge from the Alps; instead, the watersheds of the Rhone and Danube drained the northern flanks of the Alps.
The watershed of the Rhine reaches into the Alps today, but it did not start out that way. 450 km (280 mi) north of the Alps. The Rhine then had the Sieg as a tributary, but not yet the Moselle (river). The northern Alps were then drained by the Danube.In the Miocene period, the watershed of the Rhine reached south, only to the Eifel and Westerwald hills, about
Through stream capture, the Rhine extended its watershed southward. By the Pliocene period, the Rhine had captured streams down to the Vosges Mountains, including the Main and the Neckar. The northern Alps were then drained by the Rhone. By the early Pleistocene period, the Rhine had captured most of its current Alpine watershed from the Rhône, including the Aare. Since that time, the Rhine has added the watershed above Lake Constance (Vorderrhein, Hinterrhein, Alpenrhein; captured from the Rhône), the upper reaches of the Main, beyond Schweinfurt and the Moselle in the Vosges Mountains, captured during the Saale Ice-age from the Meuse, to its watershed.
Around 2.5 million years ago (ending 11,600 years ago) was the geological period of the Ice Ages. Since approximately 600,000 years ago, six major Ice Ages have occurred, in which sea level dropped 120 m (390 ft) and much of the continental margins became exposed. In the Early Pleistocene, the Rhine followed a course to the northwest, through the present North Sea. During the so-called Anglian glaciation (~450,000 yr BP, marine oxygen isotope stage 12), the northern part of the present North Sea was blocked by the ice and a large lake developed, that overflowed through the English Channel. This caused the Rhine's course to be diverted through the English Channel. Since then, during glacial times, the river mouth was located offshore of Brest, France and rivers, like the River Thames and the Seine, became tributaries to the Rhine. During interglacials, when sea level rose to approximately the present level, the Rhine built deltas, in what is now the Netherlands.
The last glacial ran from ~74,000 (BP = Before Present), until the end of the Pleistocene (~11,600 BP). In northwest Europe, it saw two very cold phases, peaking around 70,000 BP and around 29,000–24,000 BP. The last phase slightly predates the global last ice age maximum (Last Glacial Maximum). During this time, the lower Rhine flowed roughly west through the Netherlands and extended to the southwest, through the English Channel and finally, to the Atlantic Ocean. The English Channel, the Irish Channel and most of the North Sea were dry land, mainly because sea level was approximately 120 m (390 ft) lower than today.
Most of the Rhine's current course was not under the ice during the last Ice Age; although, its source must still have been a glacier. A tundra, with Ice Age flora and fauna, stretched across middle Europe, from Asia to the Atlantic Ocean. Such was the case during the Last Glacial Maximum, ca. 22,000–14,000 yr BP, when ice-sheets covered Scandinavia, the Baltics, Scotland and the Alps, but left the space between as open tundra. Loess (wind-blown topsoil dust) arose from the south and North Sea plain settling on the slopes of the Alps, Urals and the Rhine Valley, rendering the valleys facing the prevailing winds especially fertile.
As northwest Europe slowly began to warm up from 22,000 years ago onward, frozen subsoil and expanded alpine glaciers began to thaw and fall-winter snow covers melted in spring. Much of the discharge was routed to the Rhine and its downstream extension. BP. By 9000 BP, Europe was fully forested. With globally shrinking ice-cover, ocean water levels rose and the English Channel and North Sea re-inundated. Meltwater, adding to the ocean and land subsidence, drowned the former coasts of Europe transgressionally.Rapid warming and changes of vegetation, to open forest, began about 13,000
About 11000 years ago, the Rhine estuary was in the Strait of Dover. There remained some dry land in the southern North Sea, known as Doggerland, connecting mainland Europe to Britain. About 9000 years ago, that last divide was overtopped / dissected. Man was already resident in the area when these events happened.
Since 7500 years ago the situation of tides, currents and land-forms has resembled the present. Rates of sea-level rise dropped such that natural sedimentation by the Rhine and coastal processes widely compensate for transgression by the sea. In the southern North Sea, due to ongoing tectonic subsidence, the coastline and sea bed are sinking at the rate of about 1–3 cm (0.39–1.18 in) per century (1 metre or 39 inches in last 3000 years).
About 7000–5000 BP, a general warming encouraged migration of all former ice-locked areas, including up the Danube and down the Rhine by peoples to the east. A sudden massive expansion of the Black Sea as the Mediterranean Sea burst into it through the Bosporus may have occurred about 7500 BP.
At the begin of the Holocene (~11,700 years ago), the Rhine occupied its Late-Glacial valley. As a meandering river, it reworked its ice-age floodplain. As sea-level rise continued in the Netherlands, the formation of the Holocene Rhine-Meuse delta began (~8,000 years ago). Coeval absolute sea-level rise and tectonic subsidence have strongly influenced delta evolution. Other factors of importance to the shape of the delta are the local tectonic activities of the Peel Boundary Fault, the substrate and geomorphology, as inherited from the Last Glacial and the coastal-marine dynamics, such as barrier and tidal inlet formations.
Since ~3000 yr BP (= years Before Present), human impact is seen in the delta. As a result of increasing land clearance (Bronze Age agriculture), in the upland areas (central Germany), the sediment load of the Rhine has strongly increased years, approximately 80 avulsions have occurred. Direct human impact in the delta began with the mining of peat for salt and fuel from Roman times onward. This was followed by embankment of the major distributaries and damming of minor distributaries, which took place in the 11–13th century AD. Thereafter, canals were dug, bends were straightened and groynes were built to prevent the river's channels from migrating or silting up.and delta growth has speeded up. This has caused increased flooding and sedimentation, ending peat formation in the delta. In the geologically recent past the main process distributing sediment across the delta has been the shifting of river channels to new locations on the floodplain (termed avulsion). Over the past 6000
At present, the branches Waal and Nederrijn-Lek discharge to the North Sea through the former Meuse estuary, near Rotterdam. The river IJssel branch flows to the north and enters the IJsselmeer (formerly the Zuider Zee), initially a brackish lagoon but a freshwater lake since 1932. The discharge of the Rhine is divided into three branches: the Waal (6/9 of total discharge), the Nederrijn – Lek (2/9 of total discharge) and the IJssel (1/9 of total discharge). This discharge distribution has been maintained since 1709 by river engineering works including the digging of the Pannerdens canal and the installation, in the 20th century, of a series of weirs on the Nederrijn.

The Rhine was not known to Herodotus and first enters the historical period in the 1st century BC in Roman-era geography. At that time, it formed the boundary between Gaul and Germania.
The Upper Rhine had been part of the areal of the late Hallstatt culture since the 6th century BC, and by the 1st century BC, the areal of the La Tène culture covered almost its entire length, forming a contact zone with the Jastorf culture, i.e. the locus of early Celtic-Germanic cultural contact.
In Roman geography, the Rhine formed the boundary between Gallia and Germania by definition; e.g. Maurus Servius Honoratus, Commentary on the Aeneid of Vergil (8.727) (Rhenus) fluvius Galliae, qui Germanos a Gallia dividit "(The Rhine is a) river of Gaul, which divides the Germanic people from Gaul."
In Roman geography, the Rhine and Hercynia Silva were considered the boundary of the civilized world; as it was a wilderness, the Romans were eager to explore it. This view is typified by Res Gestae Divi Augusti , a long public inscription of Augustus, in which he boasts of his exploits; including, sending an expeditionary fleet north of the Rheinmouth, to Old Saxony and Jutland, which he claimed no Roman had ever done before.
Augustus ordered his general Drusus to establish 50 military camps along the Rhine, starting the Germanic Wars in 12 BC. At this time, the plain of the Lower Rhine was the territory of the Ubii. The first urban settlement, on the grounds of what is today the centre of Cologne, along the Rhine, was Oppidum Ubiorum, which was founded in 38 BC by the Ubii. Cologne became acknowledged, as a city by the Romans in AD 50, by the name of Colonia Claudia Ara Agrippinensium.
From the death of Augustus in AD 14 until after AD 70, Rome accepted as her Germanic frontier the water-boundary of the Rhine and upper Danube. Beyond these rivers she held only the fertile plain of Frankfurt, opposite the Roman border fortress of Moguntiacum (Mainz), the southernmost slopes of the Black Forest and a few scattered bridge-heads. The northern section of this frontier, where the Rhine is deep and broad, remained the Roman boundary until the empire fell. The southern part was different. The upper Rhine and upper Danube are easily crossed. The frontier which they form is inconveniently long, enclosing an acute-angled wedge of foreign territory between the modern Baden and Württemberg. The Germanic populations of these lands seem in Roman times to have been scanty, and Roman subjects from the modern Alsace-Lorraine had drifted across the river eastwards.
The Romans kept eight legions in five bases along the Rhine. The actual number of legions present at any base or in all, depended on whether a state or threat of war existed. Between about AD 14 and 180, the assignment of legions was as follows: for the army of Germania Inferior, two legions at Vetera (Xanten), I Germanica and XX Valeria (Pannonian troops); two legions at oppidum Ubiorum ("town of the Ubii"), which was renamed to Colonia Agrippina, descending to Cologne, V Alaudae, a Celtic legion recruited from Gallia Narbonensis and XXI, possibly a Galatian legion from the other side of the empire.
For the army of Germania Superior: one legion, II Augusta, at Argentoratum (Strasbourg); and one, XIII Gemina, at Vindonissa (Windisch). Vespasian had commanded II Augusta, before his promotion to imperator. In addition, were a double legion, XIV and XVI, at Moguntiacum (Mainz).
The two original military districts of Germania Inferior and Germania Superior, came to influence the surrounding tribes, who later respected the distinction in their alliances and confederations. For example, the upper Germanic peoples combined into the Alemanni. For a time, the Rhine ceased to be a border, when the Franks crossed the river and occupied Roman-dominated Celtic Gaul, as far as Paris.
Germanic tribes crossed the Rhine in the Migration period, by the 5th century establishing the kingdoms of Francia on the Lower Rhine, Burgundy on the Upper Rhine and Alemannia on the High Rhine. This "Germanic Heroic Age" is reflected in medieval legend, such as the Nibelungenlied which tells of the hero Siegfried killing a dragon on the Drachenfels (Siebengebirge) ("dragons rock"), near Bonn at the Rhine and of the Burgundians and their court at Worms, at the Rhine and Kriemhild's golden treasure, which was thrown into the Rhine by Hagen.
By the 6th century, the Rhine was within the borders of Francia. In the 9th, it formed part of the border between Middle and Western Francia, but in the 10th century, it was fully within the Holy Roman Empire, flowing through Swabia, Franconia and Lower Lorraine. The mouths of the Rhine, in the county of Holland, fell to the Burgundian Netherlands in the 15th century; Holland remained contentious territory throughout the European wars of religion and the eventual collapse of the Holy Roman Empire, when the length of the Rhine fell to the First French Empire and its client states. The Alsace on the left banks of the Upper Rhine was sold to Burgundy by Archduke Sigismund of Austria in 1469 and eventually fell to France in the Thirty Years' War. The numerous historic castles in Rhineland-Palatinate attest to the importance of the river as a commercial route.
Since the Peace of Westphalia, the Upper Rhine formed a contentious border between France and Germany. Establishing "natural borders" on the Rhine was a long-term goal of French foreign policy, since the Middle Ages, though the language border was – and is – far more to the west. French leaders, such as Louis XIV and Napoleon Bonaparte, tried with varying degrees of success to annex lands west of the Rhine. The Confederation of the Rhine was established by Napoleon, as a French client state, in 1806 and lasted until 1814, during which time it served as a significant source of resources and military manpower for the First French Empire. In 1840, the Rhine crisis, prompted by French prime minister Adolphe Thiers 's desire to reinstate the Rhine as a natural border, led to a diplomatic crisis and a wave of nationalism in Germany.
The Rhine became an important symbol in German nationalism during the formation of the German state in the 19th century (see Rhine romanticism).
At the end of World War I, the Rhineland was subject to the Treaty of Versailles. This decreed that it would be occupied by the allies, until 1935 and after that, it would be a demilitarised zone, with the German army forbidden to enter. The Treaty of Versailles and this particular provision, in general, caused much resentment in Germany and is often cited as helping Adolf Hitler's rise to power. The allies left the Rhineland, in 1930 and the German army re-occupied it in 1936, which was enormously popular in Germany. Although the allies could probably have prevented the re-occupation, Britain and France were not inclined to do so, a feature of their policy of appeasement to Hitler.
In World War II, it was recognised that the Rhine would present a formidable natural obstacle to the invasion of Germany, by the Western Allies. The Rhine bridge at Arnhem, immortalized in the book, A Bridge Too Far and the film, was a central focus of the battle for Arnhem, during the failed Operation Market Garden of September 1944. The bridges at Nijmegen, over the Waal distributary of the Rhine, were also an objective of Operation Market Garden. In a separate operation, the Ludendorff Bridge, crossing the Rhine at Remagen, became famous, when U.S. forces were able to capture it intact – much to their own surprise – after the Germans failed to demolish it. This also became the subject of a film, The Bridge at Remagen . Seven Days to the River Rhine was a Warsaw Pact war plan for an invasion of Western Europe during the Cold War.
Until 1932 the generally accepted length of the Rhine was 1,230 kilometres (764 miles). In 1932 the German encyclopedia Knaurs Lexikon stated the length as 1,320 kilometres (820 miles), presumably a typographical error. After this number was placed into the authoritative Brockhaus Enzyklopädie, it became generally accepted and found its way into numerous textbooks and official publications. The error was discovered in 2010, and the Dutch Rijkswaterstaat confirms the length at 1,232 kilometres (766 miles).

During its course from the Alps to the North Sea, the Rhine passes through four countries and constitutes six different country borders. On the various parts:
Order: panning north to south through the Western Netherlands:
Order: upstream to downstream:
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.
The Waal is the main distributary branch of the river Rhine flowing approximately 80 km (50 mi) through the Netherlands. It is the major waterway connecting the port of Rotterdam to Germany. Before it reaches Rotterdam, it joins with the Afgedamde Maas near Woudrichem to form the Boven Merwede. Along its length, Nijmegen, Tiel, Zaltbommel and Gorinchem are towns of importance with direct access to the river.
The river IJssel, sometimes called Gelderse IJssel to avoid confusion with the Hollandse IJssel, is the branch of the Rhine in the Dutch provinces of Gelderland and Overijssel. The Romans knew the river as Isala. The IJssel flows from Westervoort, east of the city of Arnhem, until it discharges into the IJsselmeer. The River IJssel is one of the three major distributary branches into which the Rhine divides shortly after crossing the German-Dutch border.
The Bergse Maas is a canal that was constructed in 1904 to be a branch of the Maas River in the Dutch province of North Brabant. The Maas splits near Heusden into the Afgedamde Maas and the Bergse Maas. The Afgedamde Maas flows north until its confluence with the river Waal to form the Merwede, while the Bergse Maas continues west as the main distributary of the Maas. Part of the Merwede rejoins the Bergse Maas to form the Hollands Diep estuary.
The Nieuwe Merwede is a canal, mainly fed by the river Rhine, that was constructed in 1870 to form a branch in the Rhine-Meuse delta. It was dug along the general trajectories of a number of minor Biesbosch creeks to reduce the risk of flooding by diverting the water away from the Beneden Merwede, and to facilitate navigation and regulate river traffic in the increasingly silted-up delta.
The Lek is a river in the western Netherlands of some 60 km (37 mi) in length. It is the continuation of the Nederrijn after the Kromme Rijn branches off at the town of Wijk bij Duurstede. The main westbound waterway is hereafter called the Lek River. The Nederrijn is, itself, a distributary branch of river Rhine.
The Alpine Rhine Valley is a glacial alpine valley, formed by the part of the Alpine Rhine between the confluence of the Anterior Rhine and Posterior Rhine at Reichenau and the Alpine Rhine's mouth at Lake Constance. It covers three countries and the full length of the Apine Rhine is 93.5 km.
Nederrijn is the name of the Dutch part of the Rhine from the confluence at the town of Angeren of the cut-off Rhine bend of Oude Rijn and the Pannerdens Kanaal. The city of Arnhem lies on the right (north) bank of the Nederrijn, just past the point where the IJssel branches off. The Nederrijn flows on to the city of Wijk bij Duurstede, from where it continues as the Lek. The once-important but now small Kromme Rijn branch carries the name "Rhine" towards the city of Utrecht.
The Pannerdens Kanaal is a canal in the Netherlands that was dredged between 1701 and 1709 to cut off a large, shallow bend of river Rhine and so improve river traffic and water regulation.
The Oude IJssel or Issel is a river in Germany and the Netherlands approximately 82 km (51 mi) long. It is a right tributary of the river IJssel. Oude IJssel means "Old IJssel" in Dutch; the Oude IJssel was the upper course of the IJssel until the connection with the Rhine was dug, possibly in the Roman era.
The Biesbosch National Park is one of the largest national parks of the Netherlands and one of the last extensive areas of freshwater tidal wetlands in Northwestern Europe. The Biesbosch consists of a large network of rivers and smaller and larger creeks with islands. The vegetation is mostly willow forests, although wet grasslands and fields of reed are common as well. The Biesbosch is an important wetland area for waterfowl and has a rich flora and fauna. It is especially important for migrating geese.
The Lower Rhine flows from Bonn, Germany, to the North Sea at Hoek van Holland, Netherlands ; alternatively, Lower Rhine may be refer to the part upstream of Pannerdens Kop, excluding the Nederrijn.
The Merwede is the name of several connected stretches of river in The Netherlands, between the cities of Woudrichem, Dordrecht and Papendrecht. The river is part of the Rhine–Meuse–Scheldt delta and is mostly fed by the river Rhine.
The name Rijnland means "Rhineland" in Dutch. When referring to the Rhine in Germany, "Rijnland" has the same meaning as "Rhineland" in English or "Rheinland" in German. However, "Rijnland" has a specific, different meaning in a Dutch context - the area along the Oude Rijn.
The Rhine–Meuse–Scheldt delta or Helinium is a river delta in the Netherlands formed by the confluence of the Rhine, the Meuse and the Scheldt rivers. The result is a multitude of islands, branches and branch names that may at first sight look bewildering, especially as a waterway that appears to be one continuous stream may change names as many as seven times, e.g. Rhine → Bijlands Kanaal → Pannerdens Kanaal → Nederrijn → Lek → Nieuwe Maas → Het Scheur → Nieuwe Waterweg. Since the Rhine contributes most of the water, the shorter term Rhine Delta is commonly used. However, this name is also used for the river delta where the Rhine flows into Lake Constance, so it is clearer to call the larger one Rhine–Meuse delta, or even Rhine–Meuse–Scheldt delta, as the Scheldt ends in the same delta. By some calculations, the delta covers 25,347 km2 (9,787 sq mi), making it the largest in Europe.
The Oude Maas is a distributary of the Rhine River, and a former distributary of the Maas River, in the Dutch province of South Holland. It begins at the city of Dordrecht where the Beneden Merwede river splits into the Noord River and the Oude Maas. It ends when it joins the Nieuwe Maas to form Het Scheur.
The Grote rivieren, literally translated Great rivers, is a landform in the Netherlands. Also, the term is commonly used for a divide in Dutch culture linking to the broader Dutch-Flemish culture.
The Vaartse Rijn is a canal connecting the city of Utrecht with Nieuwegein and the Lek river in the Dutch province of Utrecht. The Vaartse Rijn was formerly a major shipping route between Utrecht and the Rhine basin.
