The Rettbergsaue (translated from German as “Rettberg Island”) is a natural island in the Rhine River at Wiesbaden , Germany . It is situated between the main channel of the Rhine to the north and a smaller channel, the Wachsbleicharm , in the south. The Wachsbleicharm forms the border between the federal states of Hesse (of which Wiesbaden is the capital) and Rhineland-Palatinate .
57-518: The island is about 3,100 meters (10,200 ft) long and up to 400 m (1,300 ft) wide. Covering about 68 hectares (170 acres), it is one of the largest islands on the Rhine in which the river flows unhindered on both sides. The island is for the most part covered with trees and has a rich bird and plant life. Approximately 90% of the island is protected, with the remainder used for recreational and agricultural purposes. Bundesautobahn 643 crosses
114-440: A climatic compensation area and emission filter in the metropolitan area. The island lies within the course of the Rhine and contains a variety of biotopes including softwood and hardwood forest; brush border, island meadow, foredune, shore, floodlawn, and accretionary habitats. The native species are threatened by invasive species (like the horse chestnut and tree of heaven ), hybrid poplars, over-grazing, damage from canoeists,
171-413: A 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 floods. Not long before Tulla went to work on widening and straightening the river, heavy floods caused significant loss of life. Four diplomatic treaties were signed among German state governments and French regions dealing with
228-671: A predominantly westerly direction and flows into the Netherlands where it eventually empties into the North Sea . It drains an area of 9,973 km . Its name derives from the Celtic Rēnos . There are two German states named after the river, North Rhine-Westphalia and Rhineland-Palatinate , in addition to several districts (e.g. Rhein-Sieg ). The departments of Bas-Rhin and Haut-Rhin in Alsace (France) are also named after
285-683: A section of Bundesstraße 417. This project was never realized. The A 643 begins at the Dotzheim Interchange in Wiesbaden as a continuation of Schiersteiner Straße (Bundesstraße 262) to and from the city center (alternatively, southbound traffic on Schiersteiner Straße can continue on Saarstraße/ Kreisstraße 645 to Schierstein ). This interchange also includes an exit ramp to Erich-Ollenhauser Straße (K 655), which leads northwest to Wiesbaden-Dotzheim and southeast to Biebrich . The A 643 soon intersects with
342-588: A waterway in the Holy Roman Empire . Among the largest and most important cities on the Rhine are Cologne , Rotterdam , Düsseldorf , Duisburg , Strasbourg , Arnhem , and Basel . The variants of the name of the Rhine (Latin Rhenus; French Rhin, Italian Reno, Romansh Rain or Rein, Dutch Rijn, Alemannic Ry, Ripuarian Rhing) in modern languages are all derived from the Gaulish name Rēnos , which
399-747: Is a Central German development of the early modern period , with the Alemannic name R(n) keeping the older vocalism. In Alemannic, the deletion of the ending -n in pausa is a recent development; the form Rn is largely preserved in Lucernese dialects. Rhing in Ripuarian is diphthongized, as is Rhei, Rhoi in Palatine . While Spanish has adopted the Germanic vocalism Rin- , Italian, Occitan, and Portuguese have retained
456-686: Is a 8.4-kilometer (5.2 mi) short autobahn in Germany . The motorway crosses the Rhine River, connecting the cities of Wiesbaden and Mainz , the capital cities of the German states of Hesse and Rhineland-Palatinate , respectively. It is one of two autobahns in Germany that connect two neighboring state capitals in only one exit. However short the A ;643 may be, it is a vital link within
513-731: Is one of the major European rivers . The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps . It forms the Swiss-Liechtenstein border and partly the Swiss-Austrian and Swiss-German borders. After that the Rhine defines much of the Franco-German border , after which it flows in a mostly northerly direction through the German Rhineland . Finally in Germany, the Rhine turns into
570-597: Is significantly shortened from its natural course due to a number of canal projects completed in the 19th and 20th century. 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 1,232 kilometers (766 miles) by the Dutch Rijkswaterstaat in 2010. Its course is conventionally divided as follows: The Rhine carries its name without distinctive accessories only from
627-784: Is sometimes called Rhinesee ("Lake Rhine"). Besides the Seerhein , the Radolfzeller Aach is the main tributary of Untersee . It adds large amounts of water from the Danube system to the Untersee via the Danube Sinkhole . Reichenau Island was formed at the same time as the Seerhein, when the water level fell to its current level. Lake Untersee is part of the border between Switzerland and Germany , with Germany on

#1732793935986684-643: 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 m /s (100,000 cu ft/s). The Rhine and the Danube comprised much of the Roman Empire 's northern inland boundary , and the Rhine has been a vital navigable waterway bringing trade and goods deep inland since those days. The various castles and defenses built along it attest to its prominence as
741-526: The Aare . The Aare more than doubles the Rhine's water discharge, to an average of slightly more than 1,000 m /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 . Between Eglisau and Basel , the vast majority of its length,
798-665: 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 meters to 396 meters. It flows through a wide glacial Alpine valley known as the Rhine Valley ( German : Rheintal ). Near Sargan a natural dam, only a few meters high, prevents it from flowing into
855-551: The Frankfurt Rhine-Main Region , being only one of three routes across the Rhine in the region. It is an important connection between Autobahn 66 on the north bank of the Rhine and A 60 south of Mainz. The A 643 was built in 1966, together with the Mainz Ring Road, the A 60. The original plan for the highway included a section from Wiesbaden to Taunusstein -Neuhof, replacing
912-815: 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
969-457: The Obersee with the 30 cm lower Untersee . Distance markers along the Rhine measure the distance from the bridge in the old city center of Konstanz. For most of its length, the Seerhein forms the border between Germany and Switzerland. The exception is the old city center of Konstanz, on the Swiss side of the river. The Seerhein emerged in the last thousands of years, when erosion caused
1026-701: The Rhine knee , 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,
1083-400: The Rhine knee , the river turns north and leaves Switzerland altogether. The High Rhine is characterized by numerous dams. On the few remaining natural sections, there are still several rapids . Over its entire course from Lake Constance to the Swiss border at Basel the river descends from 395 m to 252 m. In the center of Basel, the first major city in the course of the stream, is
1140-750: 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 meters (11,854 ft) above sea level. It starts with
1197-680: The confluence of the Rein Anteriur/Vorderrhein and Rein Posteriur/Hinterrhein next to Reichenau in Tamins . Above this point is the extensive catchment area of the headwaters of the Rhine. This area belongs almost exclusively to the Swiss canton of Grisons ( Graubünden ), ranging from Saint-Gotthard Massif in the west via one valley lying in the canton of Ticino and Sondrio ( Lombardy , Italy) in

#17327939359861254-516: 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,
1311-806: The A 66 at Schiersteiner Kreuz. It crosses the border with Rhineland-Palatinate on the Rhine with the Schierstein Bridge . It then leads to the Hochstraße Lenneberg in the Mainz district of Mombach , through the Mainz Sand Dunes nature reserve, and ends at the Mainz Dreieck in the A 60.

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
1425-521: 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 47°39′N 9°19′E / 47.650°N 9.317°E / 47.650; 9.317 . The flow of cold, grey mountain water continues for some distance into the lake. The cold water flows near
1482-480: The High Rhine forms the border between Germany and Switzerland . Only for brief distances at its extremities does the river run entirely within Switzerland; at the eastern end it separates the bulk of the canton of Schaffhausen and the German exclave of Büsingen am Hochrhein on the northern bank from cantons of Zürich and Thurgau , while at the western end it bisects the canton of Basel-Stadt . Here, at

The island is popular with camping enthusiasts and the white-sand beaches are once again occasionally used for swimming. Because the island is free of traffic and dogs are banned, Rettbergsaue is an especially popular recreation area for families with children. The two recreation grounds are accessible from
1596-663: The Latin Ren- . The Gaulish name Rēnos ( Proto-Celtic or pre-Celtic *Reinos ) belongs to a class of river names built from the PIE root *rei- "to move, flow, run", also found in other names such as the Reno in Italy. 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, French, Spanish and Italian. The Old English river name
1653-875: 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, including Rein or Ragn , including: Next to Reichenau in Tamins
1710-512: The Rhine into Lake Constance forms an inland delta . The delta is delimited in the west by the Alter Rhein and in the east by the modern canalized section of the Alpine Rhine ( Fußacher Durchstich ). 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

1824-554: The area around the river was made more habitable for humans on flood plains as the rate of 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
1881-404: 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

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
1995-789: 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 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 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
2109-444: 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 – over three million cubic meters (110,000,000 cu ft) annually. In
2166-416: 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 going on in
2223-461: The highest elevations of the island. The western part, which had been named Karthäuser Island in the Late Middle Ages , acquired the name of Rettbergsaue in 1832 from the Baron (German Freiherr ) Carl von Rettberg. The lieutenant and adjutant of the Duke of Nassau purchased the island from the Nassau government for approximately 1,125 guilders and operated a cattle and horse breeding business there. For financial reasons, he returned possession of
2280-588: The island to Nassau only a few years later for 50,000 guilders. In 1914, Schierstein Beach was established on the western end, close to two old channels of the Rhine. Biebrich Beach was established on the northern shore in 1921. Because of heavy pollution of the Rhine, both beaches were closed in 1962. Today, the former Schierstein and Biebrich Beaches serve as recreation areas, with large playgrounds, barbecue area, several table-tennis tables, playing areas for badminton and basketball, soccer fields with goalposts, and other attractions. The Schierstein recreation area has

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

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 4 kilometers (2.5 mi) long. It connects

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 called Alter Rhein ( lit. ' Old Rhine ' ). The mouth of

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 International Commission for the Hydrology of the Rhine Basin (CHR) and EUWID contend that the river could experience a massive decrease in volume, or even dry up completely in case of drought, within the next 30 to 80 years, as a result of the climate crisis . The Rhine

The Rhine is one of four major rivers taking their source in the Gotthard region, along with the Ticino (drainage basin of the Po ), Rhône and Reuss (Rhine basin). The Witenwasserenstock is the triple watershed between the Rhine, Rhône and Po. Traditionally, Lake Toma near the Oberalp Pass in the Gotthard region is seen as the source of
