Canal

Canals and navigations are human-made channels for water conveyance (supply), or to service water transport vehicles. In the vernacular both are referred to as 'canals', and in most cases, the engineered works will have series of dams and locks creating areas of low speed current flow referred to as 'slack water levels', often just called 'levels'.
