Contour canal

Last updated

A contour canal is an artificially-dug navigable canal which closely follows the contour line of the land it traverses, in order to avoid costly engineering works such as:

Because of this, these canals are characterised by their meandering course.

In the United Kingdom, many of the canals built in the period from 1770 to 1800 were contour canals - for example, the Thames & Severn Canal completed in 1789, and the Oxford Canal completed in 1790. Later canals tended to be much straighter and more direct - a good example is the Shropshire Union Canal engineered by Thomas Telford.

    The canal network of the United Kingdom played a vital role in the Industrial Revolution. The UK was the first country to develop a nationwide canal network which, at its peak, expanded to nearly 4,000 miles in length. The canals allowed raw materials to be transported to a place of manufacture, and finished goods to be transported to consumers, more quickly and cheaply than by a land based route. The canal network was extensive and included feats of civil engineering such as the Anderton Boat Lift, the Manchester Ship Canal, the Worsley Navigable Levels and the Pontcysyllte Aqueduct.

    The Ellesmere Canal was a waterway in England and Wales that was planned to carry boat traffic between the rivers Mersey and Severn. The proposal would create a link between the Port of Liverpool and the mineral industries in north east Wales and the manufacturing centres in the West Midlands. However, the canal was never completed as intended because of its rising costs and failure to generate the expected commercial traffic.

    The canals of the United Kingdom are a major part of the network of inland waterways in the United Kingdom. They have a varied history, from use for irrigation and transport, through becoming the focus of the Industrial Revolution, to today's role of recreational boating. Despite a period of abandonment, today the canal system in the United Kingdom is again increasing in use, with abandoned and derelict canals being reopened, and the construction of some new routes. Canals in England and Wales are maintained by navigation authorities. The biggest navigation authorities are the Canal & River Trust and the Environment Agency, but other canals are managed by companies, local authorities or charitable trusts.

    The Droitwich Canal is a synthesis of two canals in Worcestershire, England; the Droitwich Barge Canal and the Droitwich Junction Canal. The Barge Canal is a broad canal which opened in 1771 linking Droitwich Spa to the River Severn at Hawford Bottom Lock, Claines. The Droitwich Junction Canal is a narrow canal, opened in 1854, which linked Droitwich to the Worcester and Birmingham Canal. Both were built to carry salt, and were abandoned in 1939. They have been the subject of a restoration plan since 1973, and the Barge Canal was officially reopened in 2010, while the Junction Canal reopened in July 2011. Following the opening of the canal, ownership transferred to the newly created Canal and River Trust

    Chirk Aqueduct is a 70-foot (21 m) high and 710-foot (220 m) long navigable aqueduct that carries what is now the Llangollen Canal across the Ceiriog Valley near Chirk, on the England-Wales border, spanning the two countries.

    The Beat Bank Branch Canal was an abortive canal near Manchester, England. It was to leave the Stockport Branch Canal in South Reddish and it was to be lock free but with a short tunnel. It was to follow the contour above the right bank of the River Tame, firstly in a northerly direction and then easterly as it followed the meandering course of the river upstream. It was to terminate at or near to the coalmining hamlet of Beat Bank in Denton where it could also secure supplies of coal from nearby mines at Haughton Green.

    A road, railway line, or canal is normally raised onto an embankment made of compacted soil to avoid a change in level required by the terrain, the alternatives being either to have an unacceptable change in level or detour to follow a contour. A cutting is used for the same purpose where the land is originally higher than required.

    The Wednesbury Oak Loop, sometimes known as the Bradley Arm, is a canal in the West Midlands, England. It is part of the Birmingham Canal Navigations (BCN), and was originally part of James Brindley's main line, but became a loop when Thomas Telford's improvements of the 1830s bypassed it by the construction of the Coseley Tunnel. The south-eastern end of the loop was closed and in parts built over, following the designation of the entire loop as "abandoned" in 1954, including the section which was filled in at the beginning of the 1960s to make way for the Glebefields Estate in Tipton.
