Épanchoir de Foucaud (siphon)

Last updated

The Épanchoir de Foucaud is a siphon for water release from the Canal du Midi west of Carcassonne. [1] The waters are used for the Épanchoir de Foucaud botanical garden.

Siphon sluice

Siphon sluices are one of the many water management devices used on the Canal du Midi to regulate the level of the water. The siphon acts as an automatic water level regulator. The épanchoir à siphon, or siphon sluice, was designed by Bertrand Garripuy (Garipuy) Jr., the son of the chief engineer. The first épanchoir siphon was built in 1776 near Capestang and the second in 1778 at Ventenac.

Canal du Midi canal in Southern France

The Canal du Midi is a 240 km (150 mi) long canal in Southern France. Originally named the Canal royal en Languedoc and renamed by French revolutionaries to Canal du Midi in 1789, the canal was at the time considered one of the greatest construction works of the 17th century.

Aqueducts on the Canal du Midi Wikimedia list article

Aqueducts on the Canal du Midi allow the canal to intersect and cross over natural streams. There are two exceptions, the first is the Herbettes Aqueduct where it crosses a four-lane highway in Toulouse. Another exception is where it intersections with the Libron river and the crossing is accomplished via the Ouvrages du Libron.

Locks on the Canal du Midi Wikimedia list article

There are 91 working locks on the Canal du Midi along its 240-kilometre (150 mi) course from the Bassin du Thau on the Mediterranean coast to the junction with the Canal lateral a la Garonne in Toulouse. There are a further 13 locks on the 37-kilometre (23 mi) La Nouvelle branch which runs through Narbonne to the Mediterranean at Port-la-Nouvelle. The locks are all under the management of the French navigation authority, Voies navigables de France.

The balancing of incoming and outgoing water allows the Canal du Midi to operate as it does. Each time a lock operates, large quantities of water are either required to fill it or dump from it into the lower level pound. There must be a constant source of water in order to fill and the excess water dumped must have a place to exit the canal without it overflowing. Being able to provide this water source was one of the most important problems to be solved by Pierre Paul Riquet, its creator.

La Nouvelle branch

The La Nouvelle branch is a 37.3-kilometre (23.2 mi) branch of the Canal du Midi in Aude, southern France which runs from the Canal du Midi through Narbonne and on to the Mediterranean. It is made up of three waterways: the first 5.1 kilometres (3.2 mi) is the Canal de Jonction from the Canal du Midi to the Aude, the second section is 800 metres (2,625 ft) of the Aude itself and the third is the 31.6 kilometres (19.6 mi) Canal de la Robine which enters the Mediterranean at Port-la-Nouvelle. The La Nouvelle branch is designated a UNESCO World Heritage Site as part of the Canal du Midi and is managed by the French navigation authority, Voies navigables de France.

Bassin de Naurouze

The Bassin de Naurouze is an octagonal holding tank, created during the building of the Canal du Midi as designed and built by Pierre-Paul Riquet. It was abandoned a few years after construction of the canal because of its recurrent silting problems. The flow of water from the Bassin de Saint-Ferréol joins the Canal du Midi at this point near the Seuil de Naurouze. Riquet hoped to build a city around the basin and also considered building a port. However, it easily filled with silt and its use discontinued. A lawn replaced the empty pool, and it is crossed by a straight path lined with plane trees.

The Bassin de Lampy was created during 1777 and 1781 when a dam was placed on the Lampy Valley in the Aude department in south-central France. The reservoir provides a source of water for the Canal du Midi. It was originally proposed in 1665 by the commission created by Louis XIV of France to evaluate Pierre-Paul Riquet's plan for the canal enterprise.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
