Contour canal

Contour canal

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 boring a tunnel through higher ground, building an embankment over lower ground, or constructing a canal lock (or series of locks) to change the level of the canal.

In the United Kingdom, many of the canals built in the period from 1770 to 1800 were contour canals - for example, the Oxford Canal. These canals are characterised by their meandering course. Later canals built from about 1810 onwards were much straighter and more direct - a good example is the Shropshire Union Canal engineered by Thomas Telford.
