river tributary

Smaller joining waterway

A river tributary is a stream or smaller river that flows into a larger river rather than directly into the sea.

The tributary feeds water into the main river, typically joining it at a confluence.

Major rivers may have dozens of tributaries: The Missouri is the longest tributary of the Mississippi.
