Heavy rainfall events data - search for fitting inspire schema/feature type for flow paths

[rihertle]

Hello, we have data representing flow paths and sinks of heavy rainfall events derived from topographical modeling. Data can be accessed here.

The sinks (MultiPolygon) represent areas where water can accumulate during heavy rain events. We thought of a mapping according to Annex III NZ (HazardArea).

For the flow paths (MultiLineString) we couldn't find a fitting featuretype inside the schema. We had the idea of a mapping according to Annex I HY-Physical Waters - "Watercourse" (as you could use the value dry under persistence) but it doesn't seem to fit the general Idea of a "A natural or man-made flowing watercourse or stream.".

Does anybody have an idea for where to fit the "flow paths".

Thank you in advance,
Rico

@sMorrone Do you maybe have an idea to whom we could reach out on that?

While I'm not a domain expert here and have no suggestions as to who you might contact, I would agree that HY-PhysicalWaters/Watercourse expects features with actual hydrological flow, so it's not quite appropriate for potential or modelled flow paths that are typically dry. The modelling of flow paths is best suited to a hazard domain, but also in my opinion the NZ theme does not have an appropriate feature type, so a specific extension should be made. I will add the community input label here, hopefully there will be some suggestions.
