Measuring a River from Source to Mouth

Ah, so now the Amazon is the longest river. Or so it claims to be. Best re-write all those pub quiz answers eh?

Saturday's connundrum. When does a river become the sea/ocean - to where do you measure? Perhaps there will never be a precise answer to that?

And did you know that the ratio of actual length of a river and straight line length is a pretty good approximation of pi?
