Kunci (key) waterway atau jalur air digunakan untuk menggambarkan aliran air baik itu yang alami maupun buatan, seperti sungai, kali atau kanal, demikian juga dengan elemen-elemen yang digunakan untuk mengendalikan aliran air seperti bendungan besar dan bendungan kecil.
Penggunaan
- Lihat juga: Waterways, Relation:waterway
Secara definisi, sebuah waterway atau jalur air diasumsikan memiliki sebuah arah aliran. Arah aliran seharusnya menuju hilir (dari sumbernya menuju muara atau mulutnya).
Untuk jalur air yang kecil, sebuah way yang mengindikasikan arah aliran dan jalurnya dirasa sudah cukup. Ketika sebuah jalur air menjadi cukup lebar (mungkin sekitar 5m atau 16.5ft), pemetaan area yang dilaluinya menjadi lebih dibutuhkan.
Jika sebuah jalur air diketahui tidak memiliki aliran air dalam lingkup satu tahun, maka selalu harus di tandai dengan intermittent=yes. (Aliran air yang tidak permanen dapat digambarkan lebih lanjut dengan penanda seasonal=* untuk menggambarkan kapan aliran air tersebut ada, namun intermittent=yes tetap harus ada dalam kasus demikian).
Sebagaimana highway atau jalan, jalur air yang panjang dapat dibagi menjadi beberapa segmen way, berbeda berdasarkan tipenya (sebuah stream akan berubah menjadi sebuah river pada titik tertentu), width=*, boat=*, dan lainnya. Jika sebuah jalur air diberi nama dari sumber hingga tujuannya, maka sangat disarankan untuk menempatkan semua segmennya ke dalam sebuah waterway relation.
Nilai (values)
Nilai waterway=* yang utama dibedakan berdasarkan rezim aliran berikut:
| Aliran Bebas | Aliran Pipa | ||||
|---|---|---|---|---|---|
| Buatan | Terbuka | tunnel=culvert |
tunnel=flooded terowongan |
man_made=pipeline
| |
waterway=canal (air yang dimanfaatkan)
|
waterway=pressurised
| ||||
waterway=ditch
| |||||
waterway=drain (air limpasan)
| |||||
| Alami | Terbuka | Gua | |||
waterway=river
| |||||
waterway=stream
| |||||
waterway=tidal_channel
| |||||
Satu-satunya pertanyaan yang diajukan untuk mendapatkan perbedaan antara aliran bebas dan aliran pipa adalah apakah air mengalir di dalam ruang tertutup dan udara dapat masuk ke dalam pipa konduit? Jika YA, maka air tidak termasuk aliran pipa dan Anda harus memilih waterway=* yang sesuai dari tabel yang ada di atas.
Bahkan jika nilai (value) waterway=* dapat diperbaiki atau diganti, maka akan sangat baik untuk mempertahankan perbedaan aliran bebas/terbuka dan fitur aliran pipa. Hal ini menjadi data yang penting untuk pengelolaan air dan perencanaan sumber daya.
Ketika memetakan beberapa fitur aliran air buatan, ingat untuk memberikan penjelasan tentang sumber masuknya air dan keluarannya dengan inlet=*, outlet=* dan man_made=outfall.

Artificial waterways | ||||||
| waterway | canal |
|
An artificial open flow waterway used to carry useful water for transportation, waterpower, or irrigation. (Other languages). | |
 | |
| waterway | pressurised |
|
A waterway where water is flowing in a fully enclosed conduit and subject to pressure; this includes gravity-driven penstocks and siphons and pump-driven pipelines, for example. |  | ||
| waterway | drain |
|
An artificial free flow waterway used for carrying superfluous water like storm water or industrial discharge, usually lined with concrete, stones or similar. | |
 | |
| waterway | ditch |
|
A small artificial free flow waterway used for carrying superfluous water for drainage or irrigation purposes, usually unlined. | |
 | |
| waterway | fairway |
|
A navigable route in a lake or sea marked by buoys. The navigable area marked by the buoys can be mapped with seamark:type=fairway.
|

| waterway | fish_pass |
|
A  fish pass, also known as a fish ladder, a fishway or fish steps, is a structure on or around artificial barriers (such as dams and locks) to facilitate diadromous fishes natural migration.
