Game 1, Round 8: Geography -- River Confluences

All questions ask about two rivers and the places where they meet,
or in some cases, larger cities within a reasonably short distance.
In some cases due to deltas the river junction is not a simple
confluence, but at least part of the flow coming from each river
does merge together.  We won't mention this in the individual
questions.
