Water Slope
A water slope () 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 (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 () was put into service on the ''Canal de Garonne, 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 (water navigation), 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 ...

Canal Inclined Plane
An inclined plane is a type of boat lift 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 ...

Jean Aubert (engineer)
Jean Aubert was a French people, French engineer. In 1961, he used the idea of the German engineer Julius Greve from the last century to describe a ''pente d'eau'' (), 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.

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 Lock (water navigation), 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 but in 2023 was still not working. 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 (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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canal De Garonne
The Garonne Canal (, ) or Canal de Garonne () is a French canal dating from the mid-19th century that connects Toulouse to Castets-en-Dorthe. The remainder of the route to Bordeaux uses the river Garonne. It is the continuation of the Canal du Midi which connects the Mediterranean with Toulouse. Together, they and the Garonne form the Canal des Deux Mers which connects the Mediterranean Sea to the Atlantic Ocean. Geography Description The canal runs along the right bank of the Garonne, crosses the river in Agen via the Agen aqueduct, then continues along the left bank. It is connected to the Canal du Midi at its source in Toulouse, and emerges at Castets-en-Dorthe on the Garonne, 54 km southwest of Bordeaux, a point where the river is navigable. The canal is supplied with water from the Garonne by two sources: * The Canal de Brienne in Toulouse, taking up to 7 m3/s from the river Garonne upstream of Bazacle dam * The Brax pumping station near Agen.

Fonserannes Water Slope
The Fonseranes Water Slope () is a disused inclined plane on the Canal du Midi parallel to the Fonseranes Locks. 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 augmenting the seven locks at the Fonseranes Locks, allowing larger boats to pass without extensive rework of the existing locks; these would continue to serve smaller boats. 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 sat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Béziers
Béziers (; ) is a city in southern France. It is a Subprefectures in France, subprefecture of the Hérault Departments of France, department in the Occitania (administrative region), Occitanie Regions of France, region. 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 the Greek colonisation, ancient Greek colony of Béziers dates from 575 BCE, making it older than Agde (Greek Agathe Tyche, founded in 525 BCE) and slightly younger ...

Canal Du Midi
The Canal du Midi (; ) is a long canal in Southern France (). 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 the start ... [...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 chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson (engineering), 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. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
