 good values, water_management might be good. Some of these are for purely 
storm surge control (to prevent short term flooding), but canals and aqueducts 
often have controlled land in certain places and are not related to storms. 

https://www.openstreetmap.org/#map=19/36.28920/137.88271 


Here is a place where an aqueduct crosses a river. the office next to it is the 
local “drainage” office that handles the aqueduct. 

the land around the crossing has two overflow drains that lead to the river. 

I could merely map the grass and riverbank areas, letting the fences and water 
features imply the usage, but I could also try to show that this junction is:

- a man-made feature
-for management of the water features inside the area
- has no other uses beyond water management. (no parks, etc).
- an area people normally don’t enter except for maintenance. 
- this one also has access control (fencing, gates, etc)

To me, this is another use of this landuse.

They often have fences or other barrier= features along with access ways. 

Smaller ones are defined by the bordering boundaries (farmland, residential 
walls, road guardrails, etc).  

All my examples were chosen because they basically have this.  One doesn’t - 
but still is a man-made structure.

I often do, but most of these are totally surrounded by concrete/asphalt (and 
often times fences to keep people from drowning).

I’m not interested (for this tag) to map any natural features - just the land 
altered and/or fenced that surrounds the basin/reservoir.

it’s to map the constructed objects that surround the water feature.

Perhaps industrial=water_management or =flood_control or something
elsemore specific would be better?

I would mainly do this for areas covered in concrete, asphal, stones,
roads, levees and other obvious man-made features, surrounded by a
fence or wall probably? And map the fence with barrier=fence lines if
known.

(You can also map the vegetation of the area (grass, scrub, woodland)
if it's present, especially if this covers a large area. That would
make more sense than describing a large are of woods as
industrial=flood_control if it is outside of the levees/dykes and
wouldn't actually be flooded.)

[Tagging] tagging the landuse of resevoirs & basins.

[John Willis via Tagging]

When mapping stormwater reservoirs and basins here in Japan, they often have a 
mappable landuse around them - the land around the basin is controlled, often 
with an access road and and fence of some type. 

Mapping the water feature is easy, but what is the landuse of the entire 
facility? it is 10% larger than the basin itself.


Here is a good example - the small amount of land around this basin “belongs” 
to the basin. the access road belongs to it. It is not a park nor are the 
access roads for private property. they are just there to access the basin in 
an emergency (a breach, cleaning etc).

In many instances, emergency stormwater basins are in parks or large factories 
- making them a feature of that larger landuse.
I'm not talking about these. 

Examples of what I’m not talking about:

https://www.openstreetmap.org/#map=16/36.1037/139.6329 



I’m talking about the dedicated land only used for the man-made basins and no 
other usage, controlled via barriers, and mappable via imagery. 

I suggest landuse=industrial + industrial=water  or similar for all man-made 
water related features that isn’t a plant of some kind (ones dedicated to 
filtering, treating, or pumping the water). 

similar to landuse=railway, there is more land dedicated to these features than 
just the mappable feature itself.

taginfo says this combination currently has 60 uses (#2 for all “water” 
values), and “water_storage” has 1.
