[Tagging] Incorrectly tagging locks on rivers as canals

[Dave F]

Hi

This maybe UK specific but it's a tagging problem & maybe wider spread.

To allow navigation, rivers occasional have lock gates, usually as a 
separate channel. Some contributors tag these incorrectly as 
waterway=canal for the centre line.

However, they are still rivers, they just have canalized sections. If 
this logic was applied to all lengths of river every one that passes 
through a city, such as the East River, Seine or Thames would be tagged 
as canal, which is of course, ridiculous.

Canals are man-made channels to allow water to flow where it naturally 
wouldn't
If the locks were removed from rivers the water would still flow.

Canal is a noun.
Canalise is a verb.
