I disagree. As I understood it, monitoring:water_level is for regularily
*monitoring* of the level, whereas the tagging searched for is for markers
of exceptionell historic high water levels. Of course, sometimes the high
water marks are placed at water level monitoring stations, but often they
are placed at buildings that are quite distant from the water, to display
the impact of the high water.

IMO historic=memorial + memorial:type=plaque is the right direction.

it appears there is already this tag in use, which might cover part of what
you are after:
monitoring:water_level

isn't this information already available when you measure the distance
and position from the marker node to the way representing the river ?
OSM is a geographical database, and e.g. Postgis will allow you to do
certain queries based on the coordinates of the objects. There is no
need to explicitly add information like distance. You can compute this
from the coordinates of the objects
To determine left/right bank you will also need the direction of the
way representing the river.

Perhaps you need a relation with the marker and the river to indicate
that the marker is for that particular river. When there are many
rivers/streams/... in an area this might not be obvious without an
explicit relation containing both elements.

So, IMHO, you should not add tags for riverbank=left/right nor
waterway:kilometer.

[Tagging] How to tag high water marks (flood marks)?

[Filip Mleczek]

Hello

I'm writing master thesis about high water marks in Cracow in Poland.
https://en.wikipedia.org/wiki/High_water_mark I have to put high water
marks to OSM.

What tags i should i use? In taginfo i only found one tag: flood_marker. It
is used only once. But term "flood mark" is not correct. It should by
called "high water mark", because this term is in International Glossary of
Hydrology.

My propositions discussed in OSM/PL forum:

Main:
high_water_mark=yes
flood_marker=yes

Location:
location=
=indoor (inside the building)
=outdoor (outside the building)
=wall (in the wall)

Mark height from the ground/floor:
height_water:height= [m]

Flood date:
flood_date=

Inscription in the mark (or part):
inscription=

History:
memorial:type= high_water_mark
memorial:type=plaque
historic=highwater_mark

Tourism:
tourism=attraction

How to describe whether it is left or the right bank of the river?
Can I use riverbank=left/right?
Or better will be riverbank:side=left/right?

Water mile https://en.wikipedia.org/wiki/River_mile is waterway:kilometer?

How to describe distance from the river?

Can you help me?

All the best.
