As well as presence other options for a new tag would be:
*persistence eg:
http://inspire.ec.europa.eu/codelist/HydrologicalPersistenceValue
*permanence eg:
https://cfpub.epa.gov/si/si_public_record_report.cfm?dirEntryId=159984
Permanence seems to be the more commonly used term.
I wouldn't include the seasonal value as there is already a seasonal key
and we should use that.
In effect what I think we need is to generalise the existing stream key:
https://wiki.openstreetmap.org/wiki/Key%3Astream
so it can be used on other water objects (assuming that people would
think that natural=wetland + stream=ephemeral would look odd--otherwise
no need for a new key).
