96-746: The Murg is an 80.2-kilometre-long river (including its headstream, the Rechtmurg ) and tributary of the Rhine in Baden-Württemberg , Germany . It flows through the Northern Black Forest into the Upper Rhine Plain , crossing the counties of Freudenstadt and Rastatt . The Murg valley is one of the largest and deepest valleys in the Black Forest (up to over 700 metres deep) and generally runs in

192-484: A sink , which may be a permanent lake, a dry lake , or a point where surface water is lost underground . Drainage basins are similar but not identical to hydrologic units , which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system . Hydrologic units are defined to allow multiple inlets, outlets, or sinks. In a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. About 48.71% of

288-414: A watershed , though in other English-speaking places, "watershed" is used only in its original sense, that of the drainage divide line. A drainage basin's boundaries are determined by watershed delineation , a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin , rather than flowing to the ocean, water converges toward the interior of the basin, known as

384-517: A continuous road was built along the bottom of the valley. The construction of the Murg Valley Railway began with independent sections from Rastatt and Freudenstadt. On the Baden side the first section from Rastatt to Gernsbach went into operation in 1869, Württemberg followed in 1901 with the route from Freudenstadt to Klosterreichenbach. After several expansion stages, a continuous railway connexion

480-413: 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

576-449: A drainage basin, and there are different ways to interpret that data. In the unlikely event that the gauges are many and evenly distributed over an area of uniform precipitation, using the arithmetic mean method will give good results. In the Thiessen polygon method, the drainage basin is divided into polygons with the rain gauge in the middle of each polygon assumed to be representative for

672-540: A drainage boundary is referred to as watershed delineation . Finding the area and extent of a drainage basin is an important step in many areas of science and engineering. Most of the water that discharges from the basin outlet originated as precipitation falling on the basin. A portion of the water that enters the groundwater system beneath the drainage basin may flow towards the outlet of another drainage basin because groundwater flow directions do not always match those of their overlying drainage network. Measurement of

768-587: A fighting withdrawal to the fortress city of Rastatt. The Murg, directly north and east of Rastatt, formed a defence line which they defended with great tenacity. The Murg Valley Railway and the Black Forest Valley Highway ( Bundesstraße 462 ) follow the Murg Valley. Both are amongst the most notable transportation routes in Germany for civil engineering and natural beauty. The gorge-like character of

It separates the precipitation-rich main crest of the Northern Black Forest , including the Hornisgrinde (1,164 m), to the west, from the densely forested bunter sandstone plateaux in the east. The Murg originates from 2 large headstreams in the western part of the municipality of Baiersbronn . Below the Schliffkopf at about 870 m above  sea level (NHN) ,

960-722: 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

1056-572: Is due to the influence of Greek orthography, while the vocalization -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 ).

1152-523: Is identical with the dialect boundary with Upper Rhine Alemannic, which is strongly defined even today, and which dominates the lower part of the Murg valley. On the lower reaches of the Murg on the Rhine Plain is an Alemannic-Franconian transition dialect with numerous South Franconian dialect features. The Murg historically was important for timber rafting. Wood was rafted first as far as Steinmauern , where it

1248-480: Is referred to as " watershed management ". In Brazil , the National Policy of Water Resources, regulated by Act n° 9.433 of 1997, establishes the drainage basin as the territorial division of Brazilian water management. When a river basin crosses at least one political border, either a border within a nation or an international boundary, it is identified as a transboundary river . Management of such basins becomes

1344-630: 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

1440-750: 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

1536-600: Is the Dead Sea . Drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important. For example, the English crown gave the Hudson's Bay Company a monopoly on the fur trade in the entire Hudson Bay basin, an area called Rupert's Land . Bioregional political organization today includes agreements of states (e.g., international treaties and, within

1632-518: 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,

1728-682: The African Great Lakes , the interiors of Australia and the Arabian Peninsula , and parts in Mexico and the Andes . Some of these, such as the Great Basin, are not single drainage basins but collections of separate, adjacent closed basins. In endorheic bodies of water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this

1824-639: 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

1920-792: The Continental Divide , northern Alaska and parts of North Dakota , South Dakota , Minnesota , and Montana in the United States, the north shore of the Scandinavian peninsula in Europe, central and northern Russia, and parts of Kazakhstan and Mongolia in Asia , which totals to about 17% of the world's land. Just over 13% of the land in the world drains to the Pacific Ocean . Its basin includes much of China, eastern and southeastern Russia, Japan,

2016-681: The Korean Peninsula , most of Indochina, Indonesia and Malaysia, the Philippines, all of the Pacific Islands , the northeast coast of Australia , and Canada and the United States west of the Continental Divide (including most of Alaska), as well as western Central America and South America west of the Andes. The Indian Ocean 's drainage basin also comprises about 13% of Earth's land. It drains

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

2208-500: 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

2304-567: 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,

2400-400: 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

2496-723: 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

2592-652: 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

The following towns and villages lie along the Murg, from source to mouth: Several dialect regions meet one another in the Murg Valley. The area around the upper reaches, around Old Württemberg Baiersbronn, forms the westernmost tip of the Swabian dialect region. The old state border with Baden further downstream

2880-508: 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,

The Murg flows from south to north through four very different valley landscapes. The Murg does not flow through the middle of its elongated catchment, but further to the east, so that more and larger tributaries join it from the west than from the east. Its western tributaries included

3648-461: The Netherlands led to a boom in the timber trade, which led to extensive clearing of the forests until the end of the century. Instead of the Murg Shipping Association, which specialized in sawn timber and did not have enough capital to manage the log trade, other timber companies took over this business. The transportation of timber was hampered by the rocky gorge in the middle valley. This section could not be traversed by rafts until 1768. As early as

3744-471: 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

3840-453: 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

4320-442: 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

Rock that is quick to erode forms dendritic patterns, and these are seen most often. The two other types of patterns that form are trellis patterns and rectangular patterns. Rain gauge data is used to measure total precipitation over

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

4704-603: 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

5184-430: The discharge of water from a basin may be made by a stream gauge located at the basin's outlet. Depending on the conditions of the drainage basin, as rainfall occurs some of it seeps directly into the ground. This water will either remain underground, slowly making its way downhill and eventually reaching the basin, or it will permeate deeper into the soil and consolidate into groundwater aquifers. As water flows through

5280-441: The drainage area is dependent on the soil type. Certain soil types such as sandy soils are very free-draining, and rainfall on sandy soil is likely to be absorbed by the ground. However, soils containing clay can be almost impermeable and therefore rainfall on clay soils will run off and contribute to flood volumes. After prolonged rainfall even free-draining soils can become saturated , meaning that any further rainfall will reach

5376-642: The drainage basin to the mouth, and may accumulate there, disturbing the natural mineral balance. This can cause eutrophication where plant growth is accelerated by the additional material. Because drainage basins are coherent entities in a hydrological sense, it has become common to manage water resources on the basis of individual basins. In the U.S. state of Minnesota , governmental entities that perform this function are called " watershed districts ". In New Zealand, they are called catchment boards. Comparable community groups based in Ontario, Canada, are called conservation authorities . In North America, this function

5472-432: The early 18th century, Wüerttemberg's timber trading companies had attempted to create a rafting route by blasting through the rock in the riverbed in order to float the logs from the upper valley down to the Rhine and the Netherlands. However, due to differences with the Bishopric of Speyer in Gernsbach, most of the Württemberg timber at Huzenbach had to be transported about 200 metres up the mountain and then transported to

Rafting became less important after the construction of the Murg Valley Railway. In 1896, the last raft floated down the river Murg. In 1913 the rafting company closed and was officially banned in 1923. In 1981, the Murg Valley Trail ( Murgtalwanderweg ) was established, running for approximately 100 kilometres following

5856-416: 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.

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

From

6624-404: The middle Murg valley was a major obstacle to the development of the transport routes for centuries. The first road from Gernsbach to the upper valley bypassed this section: the Old Wine Road ( Alte Weinstraße ), as the old trading route was called, ran steeply uphill at first and then ran along the heights of the eastern flanks of the valley. It was not until the second half of the 18th century that

6720-420: The middle and lower parts of the Mur valley, were floated down the Murg to Steinmauern, where they were dried and assembled into larger rafts. These were transported by Rhine raftsmen, who had a monopoly on this section, on the Rhine to Mannheim. At Mannheim , even larger floating wooden structures were built, some of which were rafted down to the Netherlands . In the 18th century, the great demand for logs from

The High Rhine ( Hochrhein ) begins in Stein am Rhein at the western end of the Untersee. Now flowing generally westwards, it passes over the Rhine Falls ( Rheinfall ) below Schaffhausen before being joined – near Koblenz in the canton of Aargau  – by its major tributary,

7296-643: The now gently rising hillsides the Murg runs northwest through Ottenau , past the industrial town of Gaggenau and the villages of Bad Rotenfels , Oberndorf , Bischweier and Kuppenheim , where it reaches the Upper Rhine Plain . Here it crosses under the A ;5 motorway near Niederbühl and, in the area of Rastatt , the B ;3 , the Rhine Railway the Mannheim–Basel railway (Rhine Valley Railway) . Below Rheinau

7392-506: The open Sztal 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 called Alter Rhein ( lit.   ' Old Rhine ' ). The mouth of

7488-534: 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

7584-418: The rainfall on the area of land included in its polygon. These polygons are made by drawing lines between gauges, then making perpendicular bisectors of those lines form the polygons. The isohyetal method involves contours of equal precipitation are drawn over the gauges on a map. Calculating the area between these curves and adding up the volume of water is time-consuming. Isochrone maps can be used to show

7680-625: The responsibility of the countries sharing it. Nile Basin Initiative , OMVS for Senegal River , Mekong River Commission are a few examples of arrangements involving management of shared river basins. Management of shared drainage basins is also seen as a way to build lasting peaceful relationships among countries. The catchment is the most significant factor determining the amount or likelihood of flooding . Catchment factors are: topography , shape, size, soil type, and land use (paved or roofed areas). Catchment topography and shape determine

7776-452: 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 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

7872-461: The river rather than being absorbed by the ground. If the surface is impermeable the precipitation will create surface run-off which will lead to higher risk of flooding; if the ground is permeable, the precipitation will infiltrate the soil. Land use can contribute to the volume of water reaching the river, in a similar way to clay soils. For example, rainfall on roofs, pavements , and roads will be collected by rivers with almost no absorption into

7968-583: 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 the river. Some adjacent towns are named after it, such as Rheinau , Rheineck , Rheinfelden (CH) and Rheinfelden (D). The International Commission for the Hydrology of the Rhine Basin (CHR) and EUWID contend that

8064-649: The south to the Flüela Pass in the east. 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

8160-418: The speed with which the runoff reaches a river. A long thin catchment will take longer to drain than a circular catchment. Size will help determine the amount of water reaching the river, as the larger the catchment the greater the potential for flooding. It is also determined on the basis of length and width of the drainage basin. Soil type will help determine how much water reaches the river. The runoff from

8256-412: The surface and at first does not 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

8352-551: 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

8448-415: The time taken for rain to reach the river, while catchment size, soil type, and development determine the amount of water to reach the river. Generally, topography plays a big part in how fast runoff will reach a river. Rain that falls in steep mountainous areas will reach the primary river in the drainage basin faster than flat or lightly sloping areas (e.g., > 1% gradient). Shape will contribute to

8544-477: The time taken for runoff water within a drainage basin to reach a lake, reservoir or outlet, assuming constant and uniform effective rainfall. Drainage basins are the principal hydrologic unit considered in fluvial geomorphology . A drainage basin is the source for water and sediment that moves from higher elevation through the river system to lower elevations as they reshape the channel forms. Drainage basins are important in ecology . As water flows over

8640-491: 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

8736-446: The villages of Röt , Huzenbach and Schönmünzach . After flowing through a narrow, sparsely populated and steep-sided gorge the river passes a rocky section in which are the settlements of Forbach , Gausbach , Langenbrand and Au im Murgtal . In its slowly widening valley, the villages of Weisenbach , Hilpertsau , Obertsrot , Scheuern , the town of Gernsbach and finally the village of Hörden follow in quick succession. Between

8832-692: The world's land drains to the Atlantic Ocean . In North America , surface water drains to the Atlantic via the Saint Lawrence River and Great Lakes basins, the Eastern Seaboard of the United States, the Canadian Maritimes , and most of Newfoundland and Labrador . Nearly all of South America east of the Andes also drains to the Atlantic, as does most of Western and Central Europe and

8928-535: Was dried and combined into bigger rafts. From Steinmauern the larger rafts were floated down to Mannheim and onward to the Netherlands . During the last phase of the Baden Revolution of 1849, the Murg formed the last-ditch defence line for the remanats of the revolutionary army. Driven by overwhelmingly numerous Prussian forces out of the capital Karlesruhe and much of Baden's territory, the revolutionaries staged

9024-464: 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 ,

9120-679: Was finally established in 1928, i.e. 60 years after the start of construction, and only when the respective national railways were under the sovereignty of the German Reich. Until the 19th century, the Murg was an important route for timber rafting in the valley. Timber merchants and sawmill owners in the Eberstein (later Baden) part of the valley merged to form the trading company of the Murg Shipping Association ( Murgerschifferschaft ) whose earliest statutes date to 1488. The logs felled in

9216-461: 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 0 km datum at Old Rhine Bridge in the city of Konstanz , at the western end of Lake Constance , to the Hook of Holland at 1,036.20 km.
