waterway key 用于描述水流，如河流、溪流或 boat-yards，或与水相互作用的元素，如大坝、堰等。
用法
- See also: Waterways, Relation:waterway
根据定义，假设水路具有流向。道路的方向应该是下游（从水道的源头到它的尽头）。
对于小水道，指示水流方向及其路径的方式就足够了。当水道变得足够宽（最好是 5m 或 16.5ft）时，需要绘制它流经的区域。
如果已知一条水路全年没有水流，则应始终将其标记为 intermittent=yes. (非永久流可以进一步地使用 seasonal=* 标记来描述何时存在水流，但是 intermittent=yes 在这些情况下应该仍然存在。）
如果一条水路是从源头到目的地命名的，强烈建议将其所有路径置于水路关系中. 这样做允许 Nominatim 将这些方式组合在一起，并为 OpenStreetMap 中存在的每个命名水道准确返回一个命名结果。
Values
The main waterway=* values are distinguished according to the flowing regime as follow:
| 明渠流 | 管流 | ||||
|---|---|---|---|---|---|
| 人造的 | Open air | culvert | flooded tunnel | pipeline | |
| canal (useful water) | pressurised | ||||
| ditch | |||||
| drain (superfluous water) | |||||
| 天然的 | Open air | cave | |||
| river | |||||
| stream | |||||
| tidal_channel | |||||
The only questions to ask to get the difference between Free flow and Pipe flow is Does water flow inside a closed space and can air get inside the conduit? If yes, the water can't be pipe flow and you'll have to choose for an according waterway=* value from the table.
Even if waterway=* values can be refined or replaced, it would be really nice to preserve the distinction between free/open channel and pipe flow features. It's really important data for water management and resource planning.
When mapping some human made water channelling features, remember to describe particular intakes and outfalls with inlet=*, outlet=* and man_made=outfall.
水道
用于描述不同类型的水道。在绘制河流，溪流，排水渠，运河等路径时，需要与水流方向保持一致。请参阅水道，以获取有关其用法的简介。
