The International Canal Monuments List - Part I (3238 words) |
 | Canals needed to be able to rise out of one river valley and into the next (the Ling Chu left one river on the level and did not rise to a "summit level") in order to create networks able to facilitate the bulk carriage of cargoes across considerable distances. |
 | Deriving from Italy in the 15th and 16th centuries, sophisticated modern canal engineering was evolved in France in the 16th century, culminating in the Canal du Midi, arguably the world's greatest civil-engineering project since the constructions of the Roman period. |
 | As well as adapting to canal construction in an almost virgin wilderness, this was one of the first canals built for the new technology of the steam-powered boat, which could carry passengers and goods with greater speed, regularity, and comfort than any sailing or towed vessel and which could enormously increase barge tonnages. |
