Canals are artificial channels for water. There are two types of canals: water conveyance canals, which are used for the conveyance and delivery of water, and waterways, which are navigable transportation canals used for passage of goods and people, often connected to existing lakes, rivers, or oceans. For canals used for water supply, see canals are part of an existing waterway. This is usually where a river has been canalised: making it navigable by widening and deepening some parts (by dredging, weirs or both), and providing locks with "cuts" around the weirs or other difficult sections. In France, these waterways are called lateral canals and in the UK they are generally called navigations, and the length of the artificial waterway often exceeds the natural. The individual cuts that make up such a canal system may each be called a reach. Smaller transportation canals can carry barges or narrowboats, while ship canals allow seagoing ships to travel to an inland port (: Manchester Ship Canal), or from one sea or ocean to another
