indeed -- I somehow never notes that the standard names use "sea_water"
rather than just "water". So yes, you wouldn't want to use that for
flooding in river, etc, where it is indeed, not seawater.
though may it's time to introduce "water" names, rather than adding
"flood+water", then "river_water", then "estuary_water", etc...
But there is difference in nature:

actually, wetting-=drying in tidal areas is often a big deal, as is storm
surge, so it's not out of the question to use the same names for these.
I don't see any names with "storm" or "surge" in them -- I wonder what the
storm surge modelers use?
So there are concepts only used in flood simulation, not in oceanography.

yes, because it's not, in fact sea water generally...

well, trying to keep name proliferation down, but yes, clearly the
sea_water names are not appropriate.

Indeed -- it started with climate modeling, and extended to general
oceanographic and meteorological modeling, but hydrology is new.
I'd rather see some more cross-discipline names, but adding a set for
hydrological modeling is a fine idea as well.
