An artificial waterway across land is typically referred to as a "canal." Canals are constructed to connect bodies of water, allowing for navigation, irrigation, or transportation of goods and people between different regions. These waterways are human-made and often involve the use of locks and dams to manage water levels and facilitate the movement of boats or ships across varying elevations of land. Famous examples include the Panama Canal, the Suez Canal, and the Erie Canal in the United States.
