Coordinates

[edit]

There is Nile (Q3392), Mississippi River (Q1497), Amazon (Q3783) and probable others with this property (mouth of the watercourse (P403)) and coordinate location (P625) for its location. I think it could be better if the coordinate location (P625) is a qualifier for mouth of the watercourse (P403). There is opportunity to provide property with coordinates as qualifier as well for the other side (spring (Q124714)) of the river (Q4022). The coordinate location (P625) shall not be used as standalone property for watercourse (Q355304) classes. Paweł Ziemian (talk) 12:11, 2 August 2013 (UTC)[reply]

No, you cannot point to the middle of a river. There is no official source doing that, and how would you proceed to do so? Clicking somewhere into the wild, what appears to be the middle?
Another issue: In some cases rivers have more than one mouth, and they even do not need to be conflucences with the same waterbody. However most official sources cite only one mouth. --Matthiasb (talk) 10:02, 16 October 2015 (UTC)[reply]
I think the problem is resolved with applies to part (P518) as qualifier, see for example Weser (Q1650). Paweł Ziemian (talk) 15:40, 16 October 2015 (UTC)[reply]

Just curious about the currently 4 red entries for "national historic site of Canada (Q1568567)" . Which items are these? Do they have only Q1568567 or is this in addition to the one of the "green" entries? --  Docu  at 14:52, 15 September 2013 (UTC)[reply]

Relationship to tributary

[edit]

This appears to be a compliment to tributary (P974). It seems reasonable that a watercourse should have its (probably) single mouth/outlet as a property. So:

  1. Is there any reason not to add "tributary of", "flows into", and "water mouth is on" as aliases for this property?
  2. Any reason this property shouldn't have {{Constraint:Inverse|property=tributary (P974)}} and tributary (P974) have {{Constraint:Inverse|property=mouth of the watercourse (P403)}}?

Also, just so I'm sure: This property is intended to name the water body that this water body flows into, right? Or was it also designed for cases where a mouth or fork point has its own name also? (I don't know of any of those, but it seems like such a place might have Wikipedia articles or Commons categories.) --Closeapple (talk) 23:01, 6 July 2014 (UTC)[reply]

mouth of the watercourse (P403) values are not only watercourses, but also lakes, seas etc. The latter use inflows (P200) to link back to watercourse, and so such inverse constraint wouldn't work well. 2001:7D0:81F7:B580:D875:2633:4FD3:87B9 06:35, 15 May 2021 (UTC)[reply]

Add qualifiers

[edit]

We should be able to add the qualifier left bank (Q27834806) or right bank (Q27834918). Thx --YanikB (talk) 12:46, 22 February 2017 (UTC)[reply]

Is it OK if I use instance of (P31) as qualifier and add left bank (Q27834806) or right bank (Q27834918) to it (see Rivière Maskinongé (Q20899945) ? --YanikB (talk) 21:08, 6 March 2017 (UTC)[reply]

I've removed the constraint that items with this property should also have country (P17). Rivers don't generally stay within a single country. Deryck Chan (talk) 20:37, 4 November 2017 (UTC)[reply]

Hello. There are many watercourse (Q355304) that have multiple distributary (Q591942). How can we keep the constraint and still manage to take those cases into account? Thierry Caro (talk) 18:58, 23 December 2017 (UTC)[reply]

P4614 (drainage basin) constraint

[edit]

I'm deleting this constraint, since it doesn't seem very relevant: you shouldn't need to know about a river's drainage basin (and create an item for it) before you can name its mouth or tributary. It has 36387 violations. Ghouston (talk) 06:07, 7 November 2018 (UTC)[reply]

Accept more qualifiers

[edit]

May we accept as qualifiers coordinate location (P625) and located in the administrative territorial entity (P131) ?. The draining basin is not enough to know the exact point of mouth of the watercourse (P403) described in terms of coordinates and as administrative territory. Above are an old discussion from 2013 talking about the coordinates points in the middle of the river. In my opinion, this is a concept completely obsolete since we have a much more sophisticated cartography tools to draw starting and ending point of the river. Regarding the P131, is not enough as a main property because the river usually start, cross and ends in different entity and, sometimes, different country. No argued answer, means OK.

Mouth

[edit]

The property mouth only accepts one data. But in this case Q1997895 —there are many more– the mouth changed (this can be, as in this case, by a human intervention, or for other rivers, by the forces of nature). Until 1961 the river ended in the Leybucht, directly in the see. From 1961 on it ended in the new build canal Störtebekerkanal. Both facts are important data to understand the hydrography of that river. Thank you for your help.--Flamenc (talk) 09:54, 10 June 2020 (UTC)[reply]

Left or right?

[edit]

How to specify to which side of the parent body (if sides are applicable) does the current watercourse discharge? Incnis Mrsi (talk) 17:45, 14 July 2020 (UTC)[reply]
Found Property:P3871. Why we see no documentation on availability of this qualifier? Incnis Mrsi (talk) 18:03, 14 July 2020 (UTC)[reply]

Accept start/end time as qualifiers

[edit]

Could mouth of the watercourse (P403) accept start time (P580) and end time (P582) as qualifiers? For example, Niderbach (Q109303067) changed its mouth in 2021. --Sascha (talk) 20:24, 28 October 2021 (UTC)[reply]

Looked as reasonable. Or you can specify the item as exception. — Ivan A. Krestinin (talk) 20:40, 28 October 2021 (UTC)[reply]

Type constraint too generic

[edit]

@YanikB, Saarik: why you added classes "body of water" and "still waters" under type constraint? Currently this property is incorrectly used for 128 lake items (are not watercourses). However constraint now misses these due to these too generic classes. 2001:7D0:81DA:F780:50DE:590:CB16:50C6 13:26, 14 February 2022 (UTC)[reply]

Added start and end time as qualifiers

[edit]

I've added start time (P580) and end time (P582) to the allowed qualifiers constraint (diff). Per Kirkhope Cleuch (Q24640130), the river mouth emptied into Daer Water (Q15212518) until 1956, and into the new Daer Reservoir (Q5208267) from 1956. We need start and end times to represent this common occurrence. --Tagishsimon (talk) 14:58, 6 March 2022 (UTC)[reply]
