What is an artificial waterway called?

An artificial waterway is called a canal. Canals are human-made channels used for various purposes, including irrigation, navigation, and water management. They differ from natural waterways like rivers and streams, which are formed by natural processes. Canals can help connect bodies of water, allowing for transportation of goods and people, and can significantly alter the surrounding landscape to serve specific agricultural or recreational needs. The significance of canals in both historical and contemporary contexts, such as the Erie Canal in the United States, illustrates their importance in facilitating trade and enhancing connectivity between regions.
