Water Slope
A water slope (french: Pente d'eau) is a type of canal inclined plane built to carry boats from a canal or river at one elevation up or down to a canal or river at another elevation. History In 1885, German engineer Julius Greve published drafts for water slopes in German journals. French engineer Jean Aubert advanced the studies in the 1950s and 1960s. To date, only two water slopes have been built, both in southern France. In 1973 the Montech water slope (french: Pente d'eau de Montech) was put into service on the ''Canal latéral à la Garonne''. In 1983 the Fonserannes Water Slope was inaugurated near Béziers on the Canal du Midi. Both water slopes run parallel to existing lock flights. Both water slopes are currently out of service and in disrepair. However, the slopes and their moving engines can be viewed from a distance. Operation The water slope uses a moveable gate in a sloping channel. To ascend the slope the moving gate can be opened to allow a boat to enter ...

Canal Inclined Plane
An inclined plane is a type of cable railway used on some canals for raising boats between different water levels. Boats may be conveyed afloat, in caissons, or may be carried in cradles or slings. History Inclined planes have evolved over the centuries. Some of the first were used by the Egyptians to bypass waterfalls on the Nile. These consisted of wooden slides covered with silt which reduced friction. Timeline *600BC – The Diolkos, an early Greek inclined plane, was in use. *385AD – Inclined planes were in use on the Grand Canal in China. *1167 – Nieuwedamme ''overtoom'' (a simple type of incline) was built at Ypres. *1568 – Wagon of Zafosina in use near Venice. *1777 – 3 inclined planes or 'dry wherries' began operation on Dukart's Canal, near Coalisland, in the south-east of County Tyrone in Ulster.''Hadfield's British Canals'' eighth edition Joseph Boughey Page 49 *1788 – An inclined plane was built by William Reynolds and used, for the first time in Engl ...

Julius Greve
The gens Julia (''gēns Iūlia'', ) was one of the most prominent patrician families in ancient Rome. Members of the gens attained the highest dignities of the state in the earliest times of the Republic. The first of the family to obtain the consulship was Gaius Julius Iulus in 489 BC. The gens is perhaps best known, however, for Gaius Julius Caesar, the dictator and grand uncle of the emperor Augustus, through whom the name was passed to the so-called Julio-Claudian dynasty of the first century AD. The Julius became very common in imperial times, as the descendants of persons enrolled as citizens under the early emperors began to make their mark in history.''Dictionary of Greek and Roman Biography and Mythology'', vol. II, pp. 642, 643. Origin The Julii were of Alban origin, mentioned as one of the leading Alban houses, which Tullus Hostilius removed to Rome upon the destruction of Alba Longa. The Julii also existed at an early period at Bovillae, evidenced by a very a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Aubert (engineer)
Jean Aubert was a French engineer. In 1961 he used the idea of the German engineer Julius Greve from the last century to describe a ''pente d'eau'', ( en, water slope) which was a way of moving boats up the gradient of a canal without locks. The design consisted of a sloping channel through which a wedge of water on which the boat was floating could be pushed up an incline. This concept was used in both the Montech water slope and the Fonserannes water slopes. Education *Lycée Louis-le-Grand in Paris. *1913 - École Polytechnique. Soon left for service in First world war. Returned in 1919. *1920-1922 - École nationale des ponts et chaussées. *University of Paris (Bachelor of law). Career *1922-1932 - Engineer in charge of the navigation works in Paris. *1932-1961 - Professor in the Chair of Internal Navigation at the École nationale des ponts et chaussées. ( en, National school of Bridges and Roads) *1933-1945 - General manager and later chairman of the Compagnie Natio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montech Water Slope
The Montech water slope is a type of canal inclined plane built on the Canal de Garonne, in the commune of Montech, Tarn-et-Garonne, Southwest France. It is managed by the publicly owned Voies navigables de France and by-passes a series of five locks. The slope is used for larger vessels up to 40 metres in length, while smaller boats continue to use the locks. The slope has been out of service since an engine failure in 2009, and was scheduled to reopen in the summer of 2020. Operating principles The principle of the water slope is based on a sloping channel up or down which a wedge of water retained by an (almost) watertight gate is moved. This technique was invented in the 19th century by the German engineer Julius Greve and described by the French engineer Jean Aubert in 1961. The Montech water slope was inaugurated in July 1974. An evenly sloping concrete channel is fitted with a gate at the top, round which a continuous trickle of water is allowed to flow, to compensate f ...

Canal De Garonne
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many ...

Fonserannes Water Slope
The Fonseranes Water Slope (french: Pente d'eau Fonséranes) is a disused inclined plane on the Canal du Midi parallel to the Fonseranes Lock. It has a rise of and a slope of 5°. This technique for a water slope was described by the French engineer Jean Aubert in 1961. It was designed to lift vessels of up to 350 tonnes displacement. The slope, the second and last to be constructed in France, was built between 1980 and 1983 with the intent of replacing the seven locks at the Fonseranes Locks. Trial operations commenced in May 1984. However, within weeks a number of technical problems emerged as oil leaking from the hydraulic system lubricated the concrete tracks and the wheels on the lift were unable to gain sufficient traction to raise the chamber to the top of the slope. It took until 1986 to resolve the technical, contractual, and insurance issues. This problem was never satisfactorily resolved and the slope was abandoned officially on 11 April 2001. The first water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Béziers
Béziers (; oc, Besièrs) is a Subprefectures in France, subprefecture of the Hérault Departments of France, department in the Occitania (administrative region), Occitanie Regions of France, region of Southern France. Every August Béziers hosts the famous ''Feria de Béziers'', which is centred on bullfighting. A million visitors are attracted to the five-day event. The town is located on a small Cliff, bluff above the river Orb (river), Orb, about from the Mediterranean Sea, Mediterranean coast and southwest of Montpellier. At Béziers, the Canal du Midi passes over the river Orb by means of the ''Orb Aqueduct, Pont-canal de l'Orb'', an Navigable aqueduct, aqueduct claimed to be the first of its kind. History Béziers is one of the oldest cities in France. Research published in March 2013 shows that Béziers dates from 575 BC, making it older than Agde (Greek Agathe Tyche, founded in 525 BC) and a bit younger than Marseille (Greek Massalia, founded in 600 BC ...

Canal Du Midi
The Canal du Midi (; ) is a long canal in Southern France (french: le Midi). Originally named the ''Canal royal en Languedoc'' (Royal Canal in Languedoc) and renamed by French revolutionaries to ''Canal du Midi'' in 1789, the canal is considered one of the greatest construction works of the 17th century. The canal connects the Garonne to the Étang de Thau on the Mediterranean and, along with the long Canal de Garonne, forms the Canal des Deux Mers, joining the Atlantic to the Mediterranean. Strictly speaking, ''"Canal du Midi"'' refers to the portion initially constructed from Toulouse to the Mediterranean – the Deux-Mers canal project aimed to link together several sections of navigable waterways to join the Mediterranean and the Atlantic: first the Canal du Midi, then the Garonne which was more or less navigable between Toulouse and Bordeaux, then the Garonne Lateral Canal built later, and finally the Gironde estuary after Bordeaux. Jean-Baptiste Colbert authorized t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock (water Navigation)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. Pound lock A ''pound lock'' is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Pound locks were first used in China during the Song Dynasty (960–1279 AD), having been pioneered by the Song politician and naval ...

Boat Lift
A boat lift, ship lift, or lift lock is a machine for transporting boats between water at two different elevations, and is an alternative to the canal lock. It may be vertically moving, like the Anderton boat lift in England, rotational, like the Falkirk Wheel in Scotland, or operate on an inclined plane, like the Ronquières inclined plane in Belgium. History A precursor to the canal boat lift, able to move full-sized canal boats, was the tub boat lift used in mining, able to raise and lower the 2.5 ton tub boats then in use. An experimental system was in use on the Churprinz mining canal in Halsbrücke near Dresden. It lifted boats using a moveable hoist rather than caissons. The lift operated between 1789 and 1868,Charles Hadfield ''World Canals: Inland Navigation Past and Present'', p. 71, and for a period of time after its opening engineer James Green reporting that five had been built between 1796 and 1830. He credited the invention to Dr James Anderson of Edinburgh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
