River: A body of water bearing the same name for its course
River system: A system which consists of at least two rivers. There are, however, requirements for this:
A river system has been assumed if it has
1. its source in a lake which is fed by a river of another name (e.g. Niagara River -> Lake Ontario -> St. Lawrence River)
2. its source at the confluence of two rivers, then following the longer one (e.g. Ohio -> Allegheny)
This in return means, that a longer tributary joining the main river later somewhere along its way is NOT considered a river system (e.g. Mississippi - Missouri)
N.B. I only considered information currently available in Wikipedia. The true length incl. small mountain headcreeks of unspecified length might be longer. A few rivers (Culiacán and Great Bear) were excluded due to dubious sources.
Stay tuned, South America is coming next!
