Canals or artificial waterways are waterways or engineered channels built for drainage management or for conveyancing water transport vehicles. They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers.
The Grand Canal is a system of interconnected canals linking various major rivers in North and East China, serving as an important waterborne transport infrastructure between the north and the south during Medieval and premodern China. It is the longest artificial waterway in the world and a UNESCO World Heritage Site.
The Saône is a river in Eastern France. It is a right tributary of the Rhône, rising at Vioménil in the Vosges department and joining the Rhône in Lyon, at the southern end of the Presqu'île.
The Elbe–Lübeck Canal is an artificial waterway in eastern Schleswig-Holstein, Germany. It connects the rivers Elbe and Trave, creating an inland water route across the drainage divide from the North Sea to the Baltic Sea. The canal includes seven locks and runs for a length of 64 kilometres (40 mi) between the cities of Lübeck in the north and Lauenburg in the south by way of the Mölln lakes. The modern canal was built in the 1890s to replace the Stecknitz Canal, a medieval watercourse linking the same two rivers.
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 that rises and falls.
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 is considered one of the greatest construction works of the 17th century.
The Xiang River is the chief river of the Lake Dongting drainage system of the middle Yangtze, the largest river in Hunan Province, China. It is the second-largest tributary in terms of surface runoff, the fifth-largest tributary by drainage area of the Yangtze tributaries. The river flows generally northeast through the provinces of Guangxi and Hunan, its tributaries reaching into Jiangxi and Guangdong.
The Lingqu is a canal in Xing'an County, near Guilin, in the northwestern corner of Guangxi, China.
The Briare Canal is one of the oldest canals in France. Its construction started in 1604. It was the first summit level canal in Europe that was built using pound locks, connecting the Rhone-Saône and Seine valleys. It is 57 kilometres long and is part of the Bourbonnais route from Saint-Mammès on the Seine to Chalon-sur-Saône on the Saône.
Navigable aqueducts are bridge structures that carry navigable waterway canals over other rivers, valleys, railways or roads. They are primarily distinguished by their size, carrying a larger cross-section of water than most water-supply aqueducts. Roman aqueducts were used to transport water and were created in Ancient Rome. The 662-metre (2,172 ft) long steel Briare aqueduct carrying the Canal latéral à la Loire over the River Loire was built in 1896. It was ranked as the longest navigable aqueduct in the world for more than a century, until the Magdeburg Water Bridge in Germany took the title in the early 21st century.
The Stecknitz Canal was an artificial waterway in northern Germany which connected Lauenburg and Lübeck on the Old Salt Route by linking the tiny rivers Stecknitz and Delvenau, thus establishing an inland water route across the drainage divide from the North Sea to the Baltic Sea. Built between 1391 and 1398, the Stecknitz Canal was the first European summit-level canal and one of the earliest artificial waterways in Europe. In the 1890s the canal was replaced by an enlarged and straightened waterway called the Elbe–Lübeck Canal, which includes some of the Stecknitz Canal's watercourse.
The Canal de Garonne, formerly known as Canal latéral à la 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.
The Canal latéral à la Loire was constructed between 1827 and 1838 to connect the Canal de Briare at Briare and the Canal du Centre at Digoin, a distance of 196 kilometres (122 mi). It replaced the use of the river Loire, which was unreliable during winter floods and summer droughts. Aqueducts were used to cross the Allier at Le Guétin and the Loire at Digoin. However, because of the extreme length required, an aqueduct was not built to cross the Loire at Briare until 1896, when the Briare aqueduct was constructed.
The Canal du Centre, originally known as the Canal du Charollais, is a French canal running from Digoin, where it now joins the Canal latéral à la Loire, to the Saône at Chalon-sur-Saône. It was opened in 1792 and was the first watershed canal allowing boats to pass from the north of France to the south. It is 112.1 kilometres (69.7 mi) long and has 61 locks. Most of its traffic was generated by now abandoned coal mines at Montceau-les-Mines.
The Canal de Berry is a disused canal in France which links the Canal latéral à la Loire at Marseilles-lès-Aubigny with the Cher at Noyers rejoining the Loire near Tours. With a branch from Montluçon it provided 261 kilometres (162 mi) of canal with locks 2.7 metres (8.9 ft) wide from 1840 until its closure in 1955. There is now a 15 kilometres (9.3 mi) operational segment with five locks between Selles-sur-Cher and Noyers-sur-Cher.
The Canal du Nivernais links the Loire with the Seine, following approximately the course of the river Yonne in a south to north direction. It first climbs northeast and north to cross the Morvan watershed, then roughly follows the course of the Yonne. Beginning on the Loire in the village of Saint-Léger-des-Vignes, it reaches its half-way point at the town of Clamecy and finishes at Auxerre on the Yonne.
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.
The Agde Round Lock is a canal lock on the Canal du Midi that connects to the Hérault River in Agde, France. It is almost unique because it is round, which allows a boat to turn around, and the fact that it has three sets of lock gates, each with a different water level. It was built in 1676 of volcanic stone and was originally 29.20 m in diameter, 5.20 m deep.
The Bourbonnais route is a connection of four canals in France from Saint-Mammès on the Seine to Chalon-sur-Saône on the Saône River: It includes the Canal du Loing, Canal de Briare, Canal latéral à la Loire, and Canal du Centre.
The Canal d'Orléans connects the river Loire at Orléans to a junction with the Canal du Loing and the Canal de Briare in the village of Buges near Montargis. It is entirely within the department of Loiret.
