The Grand Contour Canal in England and Wales was intended to enhance and upgrade the British canal system, but was never built.
 This canal was proposed in 1943, and again ten years later, by J F Pownall .
 Mr Pownall observed that there was a natural 'contour' down the spine of England, around the 300 ft level that connected several of the most populated areas.
 He put forward the idea that this contour could be used to define the course of a large European sized canal which contained no locks except at its entry and exit points.
 It would also serve as a water grid capable of distributing domestic water supply around England as need arises.
The British canal system of water transport played a vital role in the United Kingdom's Industrial Revolution at a time when roads were only just emerging from the medieval mud and long trains of packhorses were the only means of "mass" transit by road of raw materials and finished products.
 (It was no accident that amongst the first canal promoters were the pottery manufacturers of Staffordshire.)
 The UK was the first country to acquire a nationwide canal network.

The Grand Union Canal in England is part of the British canal system.
 Its main line starts in London and ends in Birmingham, stretching for 137 mi with 166 locks.
 It has arms to places including Leicester, Slough, Aylesbury, Wendover and Northampton.
The Susquehanna and Tidewater Canal between Wrightsville, Pennsylvania, and Havre de Grace, Maryland, at the head of Chesapeake Bay, provided an interstate shipping alternative to 19th-century arks, rafts, and boats plying the difficult waters of the lower Susquehanna River.
 Built between 1836 and 1840, it ran 43 mi along the west bank of the river and rendered obsolete an older, shorter canal along the east bank.
 Of its total length, 30 mi were in Pennsylvania and 13 mi in Maryland.
 Though rivalry between Philadelphia, Pennsylvania, and Baltimore, Maryland, delayed its construction, the finished canal brought increased shipments of coal and other raw materials to both cities from Pennsylvania's interior.
 Competition from railroads was a large factor in the canal's decline after 1855.
 Canal remnants, including a lock keeper's house, have been preserved in Maryland, and locks 12 and 15 have been preserved in Pennsylvania.
 A copy of a detailed survey blueprint of the entire canal system including structures and property ownership details was donated (date unknown) by the Safe Harbor Water Power Corporation to Millersville University (assessed on 10/06/2016 in the MU Archives at Sp.
 Coll.
 Map 386.409748 S128 Folio).
 The survey consists of 67 pages, 98 x 30 cm.
 and is undated but the assumption is the original was created while the canal was in use.
Hurleston is a civil parish in Cheshire East, England.
 It contains eight buildings that are recorded in the National Heritage List for England as designated listed buildings, all of which are at Grade II.
 This grade is the lowest of the three gradings given to listed buildings and is applied to "buildings of national importance and special interest".
 The parish is entirely rural, its main feature being the junction of the Shropshire Union Canal and the Llangollen Canal, the Hurleston Junction, and in particular the system of locks at the east end of the Llangollen Canal.
 Of the eight listed buildings, six are associated with the canal system, four locks and two bridges.
 The other listed buildings are a farmhouse and one of its farm buildings.
The Manych Ship Canal is a canal system between the basins of the Sea of Azov, Black Sea, and Caspian Sea.
 Proposals are being considered to expand the system into a larger Eurasia Canal system.
 The canal would be a multipurpose water-resources system and an important part of the national transport system serving internal and international Caspian oil traffic, with huge economic potential for the region.
 A proposed design would enlarge the Manych Ship Canal to a depth of 6.5 m and width of 80 m with traffic capacity for more than 75 million tons per year.
 This proposed Eurasia Canal would allow passage of vessels with a freight-carrying capacity of up to 10,000 tons.
 Russia's unique geographic location and transportation infrastructure does not correspond economically to the current logistics of Russian and foreign trade.
Bascote locks form a flight of four locks on the Grand Union Canal, which is part of the British canal system and connects London and Birmingham.
 The lock flight has a staircase, and at the highest lock the remains of older narrow locks can be seen.
Pennsylvania Canal "(or sometimes Pennsylvania Canal system)" refers generally to a complex system of transportation infrastructure improvements including canals, dams, locks, tow paths, aqueducts, and viaducts.
 The Canal and Works were constructed and assembled over several decades beginning in 1824, the year of the first enabling act and budget items.
 It should be understood the "first use of any railway" in North America was the year 1826, so the newspapers and the Pennsylvania Assembly of 1824 applied the term then to the proposed Right of ways mainly for the canals of the Main Line of Public Works to be built across the southern part of Pennsylvania.
 Enacted before Railroads gestated during their infancy, the focus of the act was to create through building a canal system, the capability to ship heavy or bulk goods and connect Philadelphia to Pittsburgh—and "more importantly"—and "beyond" to the "new growth markets" in the developing territories reached by the Ohio River now called the midwest.
 Later, when updated in 1837 to reflect the experience of twelve years of toddler-railways, the term was also applied to railroads and new canals to be added to the state transportation system.
 As a crowning achievement, the Main Line of Public Works and the Pennsylvania Canal system topped 2100 ft in elevation by erecting the Allegheny Portage Railroad, which used a system of five inclines and five planes on each side of the Eastern Continental Divide at Cresson Pass in Cambria County to actually haul wheeled flat cars, which had halved canal boats placed on them, up and over the Allegheny Front and connect Pittsburgh to the Susquehanna.
 When finished in 1834 the trip from Philadelphia to Pittsburgh could be made in 3–5 days, weather conditions depending.
Hatton (grid reference [ SP242670] ) is a village and civil parish about 4 mi north of Warwick, in the Warwick District of Warwickshire in England.
 It had a population of 1,078 at the 2001 Census, increasing to 2,319 at the 2011 Census.
 Notable features include a remarkable series of 21 locks on the Grand Union Canal, a shopping village (Hatton Country World) and a former psychiatric hospital (Central Hospital, Hatton) that has been turned into a large housing estate while still preserving the original Victorian buildings.
 The public house, Hatton Arms, was historically noted for its regular large assemblies of motorcycles.
 Other public houses in the area include the Falcon Inn, although less well known as it is situated further away from the village centre.
The Wendover Arm Canal is part of the Grand Union Canal in England, and forms part of the British canal system.
 It was planned as a feeder to carry water from springs near the town of Wendover in Buckinghamshire to the main line of the Grand Junction Canal at Bulbourne near Star Top End in Hertfordshire, but when it opened in 1799 it was navigable, as the extra cost of making it so was small.
 Water supplies from Wendover were found to be inadequate, and a series of reservoirs were built.
 A pumping station at Whitehouses was superseded by the Tringford pumping station in 1817; its steam engines were replaced by diesel engines in 1911 and then by electric pumps.
