I'm coming late to this discussion, so this has probably already been
discussed to death, but...

A canal is an artificial waterway which may be used for water conveyance of
for transportation.  In my part of
the world "canal" almost always means a navigable channel (strictly called
a navigation canal or just a
navigation) and doesn't convey water in meaningful amounts.  In my part of
the world, an artificial waterway used
for conveying water is almost always referred to as an aqueduct.  And yes,
occasionally an artificial waterway may
be constructed for both purposes, but it's not common.

Does that help or make matters worse?
