Canal

in Toulouse, France]] Canals are man-made waterways, usually connecting existing lakes, rivers, or oceans. They are used for transportation, often by barges or narrowboats on smaller canals, and by ships on ship canals that connect to the ocean. Inland canals preceded the development of railroads during the Industrial Revolution, and some canals were later drained and used as railroad rights-of-way.

Irrigation canals are man-made waterways for the delivery of water and preceded the use of transportation canals.

Canals have found another use in the 21st century, as wayleaves for fibre optic telecommunications networks.
