What is the difference between drainage basin And channel?

A drainage basin, also known as a watershed, is a land area where all precipitation collects and drains into a common outlet, such as a river, lake, or ocean. In contrast, a channel is a specific path or conduit through which water flows within the drainage basin, such as a river or stream. Essentially, the drainage basin encompasses the entire area contributing to the water flow, while the channel is the physical pathway that carries the water.
