Detailed explanation-1: -Streamflow, or channel runoff, is the flow of water in streams and other channels, and is a major element of the water cycle. It is one component of the movement of water from the land to waterbodies, the other component being surface runoff.

Detailed explanation-2: -A moving body of water of any size is a stream. A river is a large stream that flows downhill in a channel.

Detailed explanation-3: -streambed, also called Stream Channel, any long, narrow, sloping depression on land that is shaped by flowing water. Streambeds can range in width from a few feet for a brook to several thousand for the largest rivers. The channel may or may not contain flowing water at any time; some carry water only occasionally.
