What is a man-made waterway used for transportation?

A man-made waterway used for transportation is known as a canal. Canals are specifically constructed to facilitate the movement of goods and people, linking various bodies of water and often enhancing trade between regions. They can be engineered to include locks and other structures to manage water levels and enable navigation, making them crucial in areas where natural waterways may not be sufficient for transportation needs.

In contrast, rivers and streams are natural waterways that flow across the landscape without human alteration for transport purposes. A basin typically refers to a geographic area where water collects, but it is not specifically designed for transportation like a canal is. Thus, the defining characteristic of a canal is its deliberate construction for transportation, setting it apart from other types of water bodies.
