ditch vs. drain
How do I decide between the two? The picture and descriptions look very similar
As I see this page included in Category:Way Direction Dependent category, should I assume that the way must be draw so that the direction of the way is downstream?. If so is it better to add, as in page Tag:waterway=stream, the following sentence?
Direction of the way should be downstream.
- In my opinion neither implies the other one (there may be small ditch that is not a barrier, there may be a dry ditch that is a barrier but not a waterway) Mateusz Konieczny (talk) 08:31, 18 December 2014 (UTC)
- Both are distinctive. A waterway=ditch is for draining, a barrier=ditch for denying access. Neither implies the other. Perhaps barrier=ditch should be man_made=ditch/trench? --Jojo4u (talk) 20:40, 25 March 2015 (UTC)
For drainage and irrigation
In Asian countries, ditches are commonly used as minor irrigation channels from a larger canal or pond. How do we differentiate a ditch used for drainage from that used for irrigation? --Planemad/Talk 07:15, 13 April 2016 (UTC)
