A channel for carrying water from one place to another is called an "aqueduct." Aqueducts can be constructed from various materials, including stone, concrete, and metal, and are designed to transport water for purposes such as irrigation, drinking, and industrial use. They can take the form of open ditches, pipes, or elevated structures, depending on the terrain and the intended use.
