When a river marks an international frontier between two independent nations, if it changes its course for some reason does it still mark the frontier or do the geographical co-ordinates of the frontier take precedence?

Depends where. The St. Charles river (it is called that, right?) which marks the border between Ohio, Pennsylvania (in the US) and Ontario (Canada) changes its course and continues due north into Canada proper. The Mississipi River marks the boundary between the respective states it runs between pretty much all the way to Louisianna, which is marked by something else. I can't think of a single major river that marks the boundaries between two independant nations in its entirety, except perhaprs the Jordan river (between Israel and Jordan as of 1967), which is too small to really count.

I'm not concerned about rivers marking state or other boundaries within a single country, and the question does not ask about frontiers marked 'in entirety'. I don't know how many rivers do form part of an international frontier. It's an interesting question, and I'll post it to see if there's any response. Certainly there are some rivers which form part of the frontier between two independent countries. Possibly the best known of these is the Rio Grande between Mexico and USA. Also, to name a few others, the Rio del Plata between Argentine and Uruguay, Rio Parana between Paraguay and Brazil, Senegal River between Senegal and Mauritania, and the River Congo between Congo and Zaire.

I suspect many languages don't have punctuation marks at all but apart from subtle changes (like European style quotation marks) does any language use an entirely different system of punctuation marks to English? Which US president called his program the 'New Frontier?' Watching people in an airport this afternoon,still waving when the aircraft was a dot on the horizon,made me wonder if there is some deep-seated reason why we all wave at passing trains and departing 'planes? Why did Kenya change its pronunciation from 'Keenyer' to 'Kenya'? Were we just asked to use the proper local pronunciation when it became independent or is it a more complicated reason?
