[Talk-us] Waterway directionality in drainage canals

In many European canals, the convention is for the waterway authorities 
to arbitrarily define a direction so that a 'left' and 'right' bank can 
be defined and the appropriate navigational marks installed. So in those 
cases, where you see red on one side and green on the other, the 
nominated 'direction' can be deduced. If you face in the direction that 
places the red marks on your right & green marks on your left, then you 
are facing downstream.

Of course, that does not help you in the case of non-navigable or 
unmarked waterways.
