What's the difference between confluence and tributary?

Confluence


Definition:

  • (n.) The act of flowing together; the meeting or junction of two or more streams; the place of meeting.
  • (n.) Any running together of separate streams or currents; the act of meeting and crowding in a place; hence, a crowd; a concourse; an assemblage.
