74-511: Friedenweiler is a town in the district of Breisgau-Hochschwarzwald in Baden-Württemberg in southern Germany . It is 10 km north of Titisee-Neustadt . This Breisgau-Hochschwarzwald location article is a stub . You can help Misplaced Pages by expanding it . Breisgau-Hochschwarzwald The municipal offices are in the city of Freiburg im Breisgau which is almost entirely surrounded by Breisgau-Hochschwarzwald, but

148-490: A cold air basin , which means that under cloudless skies the heavier, cold, night air which develops on the sparsely vegetated plateaus and hills, flows into the basin and concentrates there. Especially during the cold season, such "cold lakes" can contribute to the creation of fog while all around on the plateaus the sun shines. The orography of the Neckar valley facilitates such inversive weather conditions. The Neckar valley

222-424: A 115 km long chain which had been put into the river. Through that, the trip between Mannheim and Heilbronn was shortened to two to three days. On the horse drawn ships it had previously taken five to eight days. But often the water depth was not deep enough. The vernacular name for the chain boats was Neckaresel ("Neckar donkey"). The last chain boat navigation was still done 1933 – 1935 between Neckargerach and

296-486: A downfall to the Neckar navigation. On the one hand – because most parts of the lower Neckar area had fallen to Baden and the free imperial cities of Heilbronn and Esslingen to Württemberg – the many disputes and obstructions of the former small states did not hamper the trade anymore. But during the Continental System the navigation was restricted and ships and material were confiscated. The introduction of

370-651: A pastureland in the Oberrheinische Tiefebene in a tangle of meanders, slings, old waters and cut of arms between the Rhine in the west and the foot of the Odenwald in the east until it finally entered the Rhine only north of Darmstadt at Trebur ; roughly 50 km north of today's confluence in Mannheim. On large stretches you can still see it on aerial photos. In the 13th century, the confluence

444-914: Is a 362-kilometre-long (225 mi) river in Germany , mainly flowing through the southwestern state of Baden-Württemberg , with a short section through Hesse . The Neckar is a major right tributary of the Rhine . Rising in the Schwarzwald-Baar-Kreis near Schwenningen in the Schwenninger Moos conservation area at a height of 706 m (2,316 ft) above sea level, it passes through Rottweil , Rottenburg am Neckar , Kilchberg , Tübingen , Wernau , Nürtingen , Plochingen , Esslingen , Stuttgart , Ludwigsburg , Marbach , Heilbronn and Heidelberg , before discharging on average 145 m /s (5,100 cu ft/s) of water into

518-565: Is densely populated and heavily industrialised, with several well-known companies. Between Stuttgart and Lauffen, the Neckar cuts a scenic, meandering, and in many places steep-sided, valley into fossiliferous Triassic limestones and Pleistocene travertine . Along the Neckar's valley in the Odenwald hills many castles can be found, including Hornberg Castle and Guttenberg Castle  [ de ; lb ; ru ; uk ] in Haßmersheim ;

592-597: Is drained today. Afterward, the Neckar joins with the Eschach coming from the eastern slopes of the Black Forest which is much more water bearing. Its main tributary Glasbach, which originates at the Brogen, is hydrographically seen as the main river of the Neckar river system. With this junction above Rottweil the Neckar enters a narrow, wooded valley and for the next 80 km it bores its way towards north between

666-766: Is independent of it. In addition, the council has three satellite offices in Müllheim , Titisee-Neustadt and Breisach am Rhein . Breisgau-Hochschwarzwald covers areas which are very different in scenic character: in the Upper Rhine Plain are the Markgräflerland and its foothill zone , which is continued north of the Breisgau with the hills of Kaiserstuhl , the Tuniberg and the Nimberg . Within

740-514: Is known for its wine cultivation climate and the cultivation of Trollinger , Lemberger , Kerner , Müller-Thurgau amongst other locally grown grape varieties. Wine cultivation has receded over the 20th century and cultivation of the "Württemberger Wein" is mostly restricted to the south-facing slopes with high radiation gain in the Neckar valley and its side valleys, as wine cultivation is labor-intensive and in Württemberg competitive only in

814-575: Is there a 3-kilometre-long boundary with the municipality of Vörstetten and the district of Emmendingen . The neighbouring counties are Emmendingen , Schwarzwald-Baar , Waldshut , Lörrach and the French départements of the Haut-Rhin and the Bas-Rhin . The independent city of Freiburg is surrounded by the district. The district is named after the Breisgau , a historical territory, and

888-466: The Anderssen Werft ("Anderssen shipyard"). It was put into service in 1925 and christened "Gebrüder Götz". The motor cargo ship was operated by the shipping company drove for the shipping company Ludwig und Jakob Götz, founded in 1920. One of the best known shipping companies on the Neckar, which was also involved in the upgrading of the river to a heavy shipping waterway. In 1946

962-795: The High Black Forest ( Hochschwarzwald ). The climate in Breisgau-Hochschwarzwald is very varied. Between Ihringen , the place with the highest annual average temperature in Germany, and the summit of the Feldberg, both the warmest and the coldest places in Baden-Württemberg lie in Breisgau-Hochschwarzwald. Climatically, the district is one of the warmest regions in Germany: its mean annual temperature in

1036-749: The Kocher with the highest average water drainage and the longest one, the Jagst . The Kocher tributary Lein is at its end not only longer than the Kocher, but also more water-abundant. Therefore, according to hydrographic convention, the Lein would have to be regarded as the main river of the Kocher water system, making it with then 201 kilometers the longest tributary of the Neckar. Named from source to mouth. According to LUBW-BRSWEB, LUBW-FG10, LUBW-GEZG and TK25. Drainage area mostly according to LUBW-GEZG, else measured on

1110-601: The MHPArena , the Hanns-Martin-Schleyer-Halle or the Cannstatter Wasen , the second-largest fair of Germany. The term Wasen gives a clue, that there used to be a floodplain on which the fair was held. Distinctive points in the industrial landscape of the Neckar valley are the high chimneys of the coal-fired power station Altbach/Deizisau and Heilbronn as well as the assembly halls of

1184-707: The South German Scarplands . For a long time it flowed on the high plains of the different Gäu Plateaus created through the hard chalks of the Muschelkalk . At Horb the river was redirected to the northeast due to the rift structure of the so-called Swabian Lineament , which lies roughly parallel to the escarpment of the Swabian Jura . Following that the Neckar cut into the Muschelkalk plateau between Rottweil and Rottenburg as well as

1258-487: The Baden-Württemberg State Office of Statistics (only main residences). The economy is based on tourism , wine , and forestry . Politically, the majority of the district parliament ( Kreistag ) is traditionally conservative ( CDU ), with higher levels of conservative votes the farther the distance from Freiburg (which has a green - red majority). The left half of the coat of arms show

1332-787: The Daimler-engine plant in Untertürkheim and the Audi plant in Neckarsulm. Along the Neckar's valley in the Odenwald hills many castles can be found, including Hornberg Castle and Guttenberg Castle in Haßmersheim ; the now-mothballed Obrigheim Nuclear Power Plant and the active Neckarwestheim Nuclear Power Plant are also located there. In contrast to the plains, the mostly steep slopes are often forested and in forestry use. The sun-exposed south-facing sites are frequently used for vineyards and are terraced with dry walls. There

1406-573: The Electoral Palatinate signed a trade agreement in order to start up the Neckar navigation between Mannheim and Cannstatt during a time of economical rise in the late 18th century. In 1782 the previous two and the free imperial city of Heilbronn agreed upon facilitations in the Neckar trade but which were only of administrative nature. The Neckar still remained blocked at the weir in Heilbronn. The Napoleonic times around 1800 brought

1480-587: The Mannheimer Stapels ("Mannheim stable") in 1808 meant that the merchants of Mannheim gained control over almost all Neckar trade. During the German Campaign of 1813 only small ships travelled on the Neckar, mainly military transports. The Congress of Vienna demanded the freedom of traffic on the Neckar and Rhine rivers in 1814/1815. The 550-meter-long Wilhelmskanal ("Wilhelms canal") was constructed in Heilbronn from 1819 to 1821. The reason

1554-453: The Neckar have an additional role as water reservoir and are in many places used for drinking water production. The paths usually went over the heights and only crossed the valleys where there were fords over the Neckar. This changed with the onset of industrialisation in the 19th century. It brought fundamental conflicts regarding the land usage of the flat valley plain. Large even spaces became sought after for industrial sites. The Neckar

1628-418: The Neckar near Tübingen. The river's course provides a popular route for cyclists , especially during the summer months. The slopes of the Neckar are preferred areas for high-level residential areas because they allow wide, unobstructed views. The diverse usage of raw water and waterway , as well for the production of hydropower brought with it substantial interventions into the ecological structure of

1702-530: The Neckar river on October 26, 1899. The wood from the eastern Northern Black Forest was shipped through the Neckar and then Rhine up to Holland . Because of the developing seafaring the shipbuilding had a large demand for wood. The firewood from the Schurwald was combined to up to 260 Meter long rafts in Plochingen. The Neckar gained importance as a waterway in the middle of the 16th century due to

1776-640: The Neckar), the mouth of the Fils coming down from the east, from the Swabian Jura. Beginning from here the river has been expanded into a canalised waterway. It lies up to Stuttgart in a wide, urbanized meadow, which has been built over with industry and is cut through by transportation structures. Only around the Cannstatter valley bend for a short distance it is interspersed by large park areas. Here again

1850-519: The Neckar. Another trace of the former north western extent of the Danube river network is the Eschach running from north west to south east, hence towards the primal Danube. With the retraction of the escarpment, it was tapped by a Neckar tributary and redirected by about 90° to the east. Considering river history, it was never a headstream of the Neckar. Until 2000 years ago the Neckar flowed through

1924-582: The Neckar. In the Odenwald narrow ravines and gorges lead into the Neckar from both sides, as for example, the Wolfschlucht and the Margarethenschlucht. Due to the risk of flooding the valley plains remained unsettled for a long time, but the nutritious and, due to its good structure, very arable land was intensively used for agriculture, and to a large degree the valley plains are still used agriculturally today. The fertile soil allows

1998-405: The Rhine at Mannheim , at 95 m (312 ft) above sea level, making the Neckar its 4th largest tributary, and the 10th largest river in Germany. Since 1968, the Neckar has been navigable for cargo ships via 27 locks for about 200 kilometres (120 mi) upstream from Mannheim to the river port of Plochingen, at the confluence with the Fils . From Plochingen to Stuttgart, the Neckar valley

2072-572: The Rhine river. The Rheinschiffahrtsakte ("Mannheim Act") from 1831 and in consequence of it the Neckarschiffahrtsordnung ("Neckar navigation regulations") from 1832 brought, through simplified regulations and tariffs a significant rise for the navigation. But because of its shallows and rapids the river was considered one of the most dangerous in Germany. In 1836 the Neckarschiffergilde ("Neckar shipping guild")

2146-518: The Rhine valley is 11 °C (52 °F), its average rainfall is approximately 900 mm (35 in), and it has about 1,800 hours of sunshine annually. Moreover, the highest temperature ever measured in Germany , 40.2 °C (104.4 °F), was recorded on 13 August 2003 in the municipality of March . March shares this record with Gärmersdorf near Amberg , Freiburg and Karlsruhe . The County of Breisgau ( Grafschaft Breisgau ) and County of Baar ( Grafschaft Baar ) were formed on

2220-411: The Swabian Jura ( Albtrauf ). Near Weitingen the valley is traversed by the 127 m high Neckar Viaduct of the A 81. At Rottenburg it enters the wider valley of Tübingen. After Tübingen the valley narrows again. From here onwards, the surrounding elevated grounds are considerably more densely populated. Middle reaches At Plochingen the Neckar turns sharply north west at the "Neckarknie" (knee of

2294-470: The background map. Distances preferably according to the data sets of the LUBW-FG10, rarely measured on the background map. Namen preverably according to TK25. The Neckar touches, from the source to the mouth, the following districts, cities and municipalities: The primal Neckar started off as an escarpment riverlet due to the slow rise of the Black Forest and the connected slow erosive retraction of

2368-451: The barrage Kochendorf. The world's first motorboat made during the summer of 1886 by Gottlieb Daimler and Wilhelm Maybach was named "Neckar" when their Standuhr ( grandfather clock ) petrol engine was tested on the river near Bad Cannstatt. The motorized cargo navigation began on the Neckar in 1925. The first motor cargo ship on the river was ordered by the brothers Ludwig (1887–1955) and Jakob Götz (1890–1977) already in 1924 at

2442-481: The beginning upper German trade. Despite many interventions in the river course in order to improve navigation, the river which had a towpath , was because of dangerous rapids and shallows only navigable for smaller barges and this mostly only up to Heilbronn. Making the upper Neckar navigable was then pushed ahead by Christoph, Duke of Württemberg who got the necessary permission from Emperor Karl V. in 1553. The city of Heilbronn still insisted on its rights so that

2516-564: The best sites. Various excavations of harbor installations and findings lead to the conclusion that the Neckar navigation already existed during the Roman Age in the first century. Especially on the lower Neckar. Main purpose was probably the transportation of construction material for the Limes and provisions. Later the Neckar navigation was probably restarted by the Franks. Starting from 1100

2590-517: The city better from the more frequent flooding through overflow of the duct, the river received more space through a new, mostly open riverbed. This riverbed runs largely on the newly constructed horticultural show ground, which was used as the occasion for the remodeling. Headwaters Up to shortly before Rottweil the Neckar is only a small rivulet on the Baar plateau. In Deißlingen -Lauffen it has its only, 4 meters (13 ft) high, waterfall which

2664-475: The city, lastly in 1784 and 1789. The situation was then relaxed through the straightening of the river bed by means of for breakthroughs in combination with the lowering of the river bed as well as fortifications and dams. After consolidation of the situation in the 18th century, electoral palatinate market ships regularly travelled on the lower Neckar river. On the upper Neckar boats regularly travelled between Heilbronn and Cannstatt for several years around 1720;

2738-651: The colors of Austria , and the right side the colors of Baden , as parts of the District belonged to both states at various times. In the middle, the coat of arms shows an eagle , taken from the coat of arms of the Princes of Fürstenberg . The coat of arms was granted in 1974, and it is very similar to the coat of arms of the previous Freiburg district. 47°57′N 7°51′E  /  47.95°N 7.85°E  / 47.95; 7.85 Neckar The Neckar ( German pronunciation: [ˈnɛkaʁ] )

2812-589: The continuous traffic on the river was for several centuries blocked. An annoyance for the neighbours. The permission of passage for raftsman therefore had to be determined contractually. In 1342 Württemberg, the Markgrafschaft Baden and the free imperial city signed an agreement for the opening of the Neckar for rafts between Besigheim and Heilbronn. A treaty from 1476 between the free imperial city Esslingen, Württemberg and Austria fixed free rafting trade as well. The last raft went through Tübingen down

2886-578: The cultivation area of the Württemberg wine region . The vineyards at the lower reaches from Heinsheim to Heidelberg are part of the Baden wine region . Until the end of the 19th century, vineyard cultivation was more extensive in the Neckar valley including unfavorable sites. Today these have been abandoned and gone fallow, reclaimed by wildlife. One example is the southern slopes of the Spitzberg above

2960-492: The cultivation of lucrative specialty crops like vegetables or hops , for example, between Rottenburg and Tübingen. Gravel pit quarrying in the valley plains takes away agricultural land, but created large lakes, nowadays used for recreational purposes. These borrow pits also became habitat for birds, amphibians and aquatic creatures. Such large borrow pits can be found for example near Kirchentellinsfurt and between Freiberg am Neckar and Pleidelsheim . The gravel bodies of

3034-810: The district, the Black Forest covers the side valleys opening onto the Rhine Plain - the Glottertal , the valley of the Dreisam , the Höllental and the Münstertal - the High Black Forest with its highest peak, the Feldberg (1493 m), and extends as far as the plateau of Baar . In the centre of Breisgau-Hochschwarzwald lies the territory of the city of Freiburg, which is almost entirely surrounded by Breisgau-Hochschwarzwald. Only on its northern side

3108-499: The expansion of the navigation to the Württembergian Plochingen further up the river failed due to the free imperial city of Esslingen . While the electoral palatinate shipping on the lower Neckar was quite successful, the shipping on the upper Neckar was soon stopped again as the river was not suitably enough expanded for a navigation and moreover no funding was available for the further upgrading. Württemberg and

3182-521: The former rural districts of Freiburg , Müllheim and Hochschwarzwald (with its head office in Neustadt in the Black Forest). In addition, the municipality of Unadingen from the district of Donaueschingen was incorporated. Other municipalities were integrated into the city of Freiburg. The southern part of the district of Müllheim went to Lörrach and some municipalities were transferred from

3256-628: The hands of the House of Habsburg (see Anterior Austria ). The Swabian princes of Fürstenberg dominated the Baar, while the area south of Freiburg, the Markgräflerland , ended up with the margraves of Baden . In 1805/06, after the end of the Napoleonic wars , the region became part of the Grand Duchy of Baden . The district of Breisgau-Hochschwarzwald was established as part of the district reform of Baden-Württemberg on 1 Jan 1973, mainly from

3330-427: The hard Muschelkalk. The best known cut-off meander spur is the one at Lauffen ; it cut through in historical times and created a waterfall (historic: Laufen ). At the cutbanks one can find rocks, formed by the limestone of the upper Muschelkalk. For example, the rock gardens at Hessigheim . They lie on the marls and clays of the middle Muschelkalks and can sag in whole stone packages, so-called Schollen , down towards

3404-515: The heavy barges on the towpath upriver. The reason was that the steam ships were not yet strong enough herefore. The competition of rail transport made steam ships as well as towing barges gradually uneconomic in the second half of the 19th century. Rafting on the other hand kept its importance, but adapted to the age of the railroad. Because trunks from the Black forest did more and more go by train to Heilbronn and only from there continued their trip on

At Neckargemünd the Elsenz enters from the left, its lower reaches using a part of the Neckars former Maurer river loop which extended far south. At the city of Heidelberg , which borders in

3552-415: The local red wine grapes Trollinger , Schwarzriesling and Lemberger are cultivated, which are also traditionally mostly drunk in Württemberg . Especially the middle Neckar around Besigheim and Lauffen is characterized by in parts extremely steep vineyards, which can be cultivated only by hand. The vine terrasses at the Neckar together with the drainage area of the tributaries deliver the largest part of

3626-643: The name in German is masculine (der Neckar). Drainage area The headwater region of the Neckar lies in the Schwenninger Moos between Schwenningen and Bad Dürrheim . The traditionally marked spring of the river lies in the city park Möglingshöhe in Schwenningen. Prior to the Landesgartenschau Villingen-Schwenningen 2010, the Neckar flowed in the city center of Schwenningen mostly underground. In order to protect

3700-654: The north the Odenwald and at the south the Königstuhl (Odenwald) , the Neckarvalley is cut in the deepest by over 400m through mountains. After passing the Heidelberger historic city, the river enters the wide Upper Rhine Plain and after further about 25 kilometers in Mannheim roughly at its middle it enters the Rhine from the right. The largest tributaries of the Neckar are the Enz with the largest drainage area,

3774-401: The now-mothballed Obrigheim Nuclear Power Plant and the active Neckarwestheim Nuclear Power Plant are also located there. Traditionally the fertile plains have been intensively used for agriculture and its steep valley sides as vineyards . The name Neckar may be derived from Nicarus and Neccarus from Celtic Nikros , meaning wild water or wild fellow . The grammatical gender of

Later, more municipalities were incorporated into the city of Freiburg: Munzingen on 1 July 1973, Hochdorf on 1 September 1973 and Ebnet and Kappel on 1 July 1974. On 1 September 1973, the municipality of Schönenbach, which belonged to the district of Waldshut, was added. On 1 January 1974 Kiechlinsbergen was ceded to Emmendingen. On 1 April 1974 Leiselheim followed. On 18 March 1975 Grünwald

3922-440: The other two of its large tributaries: First its water-richest tributary, the Kocher and then the officially longest, the Jagst , in total roughly doubling its discharge. Lower reaches Between Bad Wimpfen with its Stauferpfalz and Mosbach , the Neckar enters the Odenwald , where, again in a gorge-like valley, high, elevated, forested slopes line its riverside and especially on the right side, deeply cut valleys enter. At

3996-400: The primal lone to the primal Danube . Another influence on this river area was the Schurwald , a dissected cuesta of the filder rift, working as a river guideline. Today's lower reaches used to be those of the primal Enz . Until, through the erosive retraction of a tributary of the primal Enz near Besigheim, the Neckar river network was tapped. That is how the Enz became a tributary of

4070-655: The ranges of the Black Forest and the Swabian Jura . It has created two cut-off meander spurs at the Neckarburg which is spanned by the Neckarburgbrücke. Further down the river lies high above the river the old town of Oberndorf on a Calcareous sinter terrace , which fills one of the bowl-like side valleys. At Horb it turns from the Gäu Plateau towards north east and then follows the western side of

4144-413: The right north of Marbach the Murr . After passing the Hessigheimer Felsengärten the water-rich Enz enters from the left at Besigheim . The former rapid at the Lauffener avulsion of the meander is today under water due to the canalization. In the Lowlands around Heilbronn the Neckar runs again through a wide meadow an open landscape. At Bad Friedrichshall it takes up within only two kilometers

4218-429: The river was blocked at Heilbronn which meant that the upper Neckar and therefore Württemberg remained cut off from the navigation coming from the Rhine. All shipped goods were subject to Heilbronner staple right . In the late 16th century, Duke of Württemberg, Frederick I had plans for the navigation passage but discarded those in 1598 and instead planned to construct a württembergian trade port in Kochendorf . – which

4292-417: The river. Multiple initiatives are advocated for the land restoration the Neckar, the ecological enhancement of the river network, the improvement of the water quality , improved flood control and the creation of attractive local recreational areas alongside the river. Only recently within the frame of the nationwide campaign lively rivers and the initiative Lebendiger Neckar (German: lively Neckar), it

In the area of the narrows the meander and cut-off meander spurs stand out. The meanders were formed through the primal Neckar, which sluggishly flowed through the almost even Muschelkalk plateau, forming the basic structures during the deepening phases and cutting into

4440-419: The territory of the present district in the 8th century. Both counties belonged to the Duchy of Alemannia . The eastern part, the upper reaches of the Danube and Neckar , came under the Carolingian dominion of the Ahalolfings . Following the disintegration of the Frankish Empire in 843, the area became part of East Francia and part of it, from 920, the Duchy of Swabia . In 1368, the Breisgau went into

4514-412: The usage of the Neckar as a waterway with line boats and rafts has been attested. The river was already blocked by weirs in the surroundings of several cities during the High Middle Ages. In Heilbronn a harbour was mentioned for the first time in 1146. The Neckar privilege granted by Holy Roman Emperor Louis IV in 1333 allowed the free imperial city the construction of a weir. After its construction,

SECTION 60

4588-492: The valley became the only possibility for modern transportation infrastructure. Construction of railway lines and avenues in the valley plains changed the Neckar valley from a cultural to an industrial landscape. One example is the densely populated and industrialised Neckar valley between Plochingen and Bad Cannstatt , which harbors large companies such as Daimler AG (the maker of Mercedes Benz cars) and Mahle GmbH and recreational facilities with large area consumption like

4662-437: The valley sides show limestone-sinter. Between Stuttgart and Lauffen the Neckar cuts a scenic, meandering, and in many places steep-sided, valley into fossiliferous Triassic limestones and Pleistocene travertine . After Stuttgart it turns again towards the general northern direction. In a winding and narrow valley section through the Ludwigsburg (district) the Rems enters from the right at Remseck and then again from

4736-449: The water, a new rafting harbour was constructed in Heilbronn in 1875. Above Esslingen the rafting was only of little importance. The last raft passed the city on 28. Oktober 1899. A new recovery for the Neckar navigation came with the chain boat navigation begun in 1878. Despite the construction of a railroad line along the Neckar. Between Mannheim and Heilbronn steam towboats with attached barges were now able to pull themselves upriver on

The river deepening was also caused by the further rise of the Black Forest as well as the retracting erosion of the attacking younger Neckar route. This younger Neckar route tapped the primal Neckar system at Plochingen (hence the Neckarknie ), which flowed through

4884-505: Was added from the district of Waldshut was added (moving from Bonndorf im Schwarzwald to Lenzkirch ). The three old districts were formed in 1939 from the Amtbezirke of the same name that had been established in the early nineteenth century when large numbers of them were formed as the area became part of Baden. In the course of the history the Amtsbezirke were changed several times, until in 1936 only those of Freiburg, Müllheim, Neustadt im Schwarzwald and Staufen were left. Staufen

4958-460: Was also the reason for the relocation of the Neckar. After the old Neckar was cut off in early 1869, it followed the path of the new Neckar breakthrough, which was finished by 1880. Narrow and widening valleys alternate along the Neckar's course. The narrows are mostly deepenings into the Muschelkalk plateau and the Buntsandstein below. Widenings developed in the area of morphologically soft clay and marl. Wide valley meadows also developed through

5032-423: Was as unsuccessful as his successors plans to build one in Untereisesheim . During the times of need in the 17th century, the navigation was insignificant. Immediately above Mannheim interventions were necessary due to regular floods. After 1622, smaller corrections were made at the back then-existing Neckar loops between Mannheims Feudenheim and today's Friedrich-Ebert-Bridge. Floods still occurred and threatened

5106-513: Was begun to free it from its partly-existing concrete corset. The river has in parts been redeveloped as a local recreational area and habitat for animals and plants. It still remains a symbol of endangered nature with the highest power plant density in Germany. At an oxygen content of below 4 mg/L power plant owners have to run specially designed turbines to inject air into the water. As of 2003, no mass die-off of fish due to lack of oxygen had occurred for 20 years. The Neckar valley functions as

With the ratification of the Neckarschiffahrtsordnung in 1842 all Guilds were dissolved and thereby economic freedom created. From 1841/42 onwards the Heilbronn-based Neckar-Dampfschifffahrt introduced a regular passenger and general cargo transport from Heilbronn to Mannheim. Despite the usage of modern steam ships, horses still pulled

5254-512: Was divided between Freiburg and Müllheim. The district of Neustadt, founded in 1939, was renamed Hochschwarzwald in 1956. Following the completion of the municipal form, the district of Breisgau-Hochschwarzwald comprised 50 municipalities, including ten towns. There are no large county towns. The largest town is Müllheim , the smallest municipality is Heuweiler . The most recent town is Bad Krozingen (from 1 September 2005).
