Proposal talk:Flood assets
Unphysical and not purposeful
The vals are redundant with what feature they are, natural=* or barrier=* , and you are reinventing the data structure already found in eg natural=wetland + wetland=mangrove , or whatever *=mixed_forests is supposed to be. Even for eg flood_assets=yes , how do you determine this on the ground? They may be natural not built specifically, or be multi-purpose. Aside from erosion, is tsunami or wave overtopping considered as related to flooding? The latter is not the same as storm surge, inundation, or river runoff.
You should simply select these features to be included in your database. A buffer and DEM can do.

I work in flood risk. A couple of observations:
For man-made assets, like barrier=*, the tag would add that it was built for a specific purpose....however, you wouldn't know that on-the-ground.
For natural assets, they can be used deliberately for flood prevention elsewhere as there is a sluice gate that can be opened to redirect water into it.
A natural asset may naturally act as a flood prevention asset by flooding. These assets might need maintaining which would then lead to a tag....again, not known on-the-ground Jnicho02 (talk) 14:56, 4 February 2024 (UTC)
- To be clear, I'm not opposing to eg a insulation=floodproof (the closest format I can think of from Proposal:Insulation proposal that mentions water) or flood_defence=yes (can be expanded as eg flood_defence=dedicated , flood_defence=shared for whether they are purpose-built, or multi-purpose). But even then, this is defined for "contributing to flood defense or coastal protection functions." . It's already not limited to flooding, ie erosion if waves are included in "flooding". "Flooding" is also not as clear as showing whether it is for "natural" weather causes, or low-lying land (viz Netherlands) and perhaps sea level rise.

man_made=dyke
What about man_made=dyke? Should that tag be replaced by flood_asset=levee? What main tag is suitable then? --Romwriter (talk) 17:41, 4 February 2024 (UTC)
Is this tag in addition to existing tags?
I was assuming that this is additional to existing tagging, eg. Barrier:bank is also a flood_asset.because it was built for that purpose. Can you clarify please? Jnicho02 (talk) 18:06, 4 February 2024 (UTC)
