Wikidata:WikiProject Rivers
This is the project that will try to maintain and improve river items in Wikidata.
The project started with lists taken from English Wikipedia, en:List of rivers of Europe and similar articles.

River Properties
[edit]In Wikidata there are several properties to describe rivers and other waterways.

How to use
[edit]- Add one of the properties P31 (river, canal, stream) to the watercourse.
- Add the mouth of watercourse to the watercourse. This might be the next larger river, an estuary or a sea.
- The coordinate of the watercourse is usually placed at its mouth, where it discharges to the next river or sea.
Notes
[edit]- OpenStreetMap relation ID (P402) can be used to link a watercourse or body of water to its corresponding relation in OSM but there are no properties for nodes or ways (previous proposals were rejected because OSM IDs are not stable enough). If you want to link OSM and Wikidata, it's a good idea to add Wikidata tags to the objects in OpenStreetMap.
Watercourses, waterbodies and systems
[edit]Waterways can flow into other waterways like rivers, canals and stream or into waterbodies.
Here is a list of different watercourses: main stream (Q573344), river (Q4022), stream (Q47521), tidal creek (Q27250), canal (Q12284), gracht (Q523166), watercourse (Q355304),
Here is a list of geographical objects (mostly waterbodies) where a watercourse might flow into (mouth of the watercourse (P403) possible values) : ocean (Q9430), sea (Q165), mediterranean sea (Q986177), adjacent sea (Q1973404), marginal sea (Q204894), strait (Q37901), gulf (Q1322134), bay (Q39594), bayou (Q812585), harbor (Q283202), inlet (Q1172599), sound (Q491713), cove (Q31615), firth (Q558116), fjord (Q45776), fjard (Q319714), estuary (Q47053), wetland (Q170321), group of lakes (Q5926864), lake (Q23397), glacial lake (Q211302), salt lake (Q188025), salt pan (Q935277), rift lake (Q6341928), volcanic crater lake (Q204324), endorheic lake (Q12779976), pluvial lake (Q7205721), Rift Valley lakes (Q2915867), meromictic lake (Q1165822), monomictic lake (Q4862338), reservoir (Q131681), ribbon lake (Q2623499), artificial pond (Q3253281), lagoon (Q187223), estuarine lagoon (Q3705882)
Watercourses are part of watersystems: drainage basin (Q166620), drainage system (Q285451)
