Ship canal

A ship canal is a canal especially constructed to carry ocean-going ships, as opposed to barges. Ship canals can be enlarged barge canals, canalised or channelized riverss, or canals especially constructed from the start to accommodate ships. 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. The purpose of a ship canal is: \n# To create a shortcut and avoid lengthy detours. \n# To create a navigable shipping link between two land-locked seas or lakes. \n# To provide inland cities with a direct shipping link to the sea.
