Ship canal

Ship canals are either enlarged barge canals, canalised rivers[?], or canals specially constructed from the start.

In order for a canal to qualify as a Ship canal, it must have a minimum depth of at least 5 metres (16.4 feet), although many are much deeper than this.

Ship canals are constructed for one of three reasons.

1. To create a shortcut, and avoid lengthy detours.
2. To create a navigable shipping link, between two land-locked seas or lakes which did not exist before.
3. To provide inland cities with a direct shipping link to the sea.
