What is an artificial waterway constructed for boat or ship passage called?

The correct term for an artificial waterway constructed specifically for boat or ship passage is a canal. Canals serve as man-made routes that facilitate maritime travel and transport by connecting existing bodies of water or providing a passageway across land. They are typically designed with specific dimensions to accommodate different types of vessels, ensuring that ships can navigate safely from one location to another. Canals have been historically significant in trade, agriculture, and industry, making them an essential infrastructure component for maritime activities.

Rivers are natural waterways, and while they can also be used for navigation, they are not constructed intentionally by humans for the purpose of passage. Lakes are large inland bodies of water and do not fit the definition of a waterway constructed for transportation. Basins refer to depressions that can contain water, such as natural or artificial reservoirs, and do not describe a specific channel or passageway meant for navigating vessels.
