Hello, there.

I would like to map some waterways and related features in karst regions, but I have some questions to do so:

  • isn't there a way to distinguish the different types of sinkholes? As far as I know, there is only natural=sinkhole, but that can designate the same a karst spring, an estavelle, a doline, (which is a sinkhole filled with clay of such materials, so there is no real hole), and a losing stream. How to distinguish them when mapping?
  • I know some partly or totally losing streams; I suppose I have to set the stream bed between them as intermittent, but, when a stream loses to reappear in a different stream bed, shouldn't I map this link? If so, how?
  • I also know a place where a closed iron mine collapsed, creating a funnel-like formation, similar to a sinkhole, but man made; should I still map it as natural=sinkhole?
  • when mapping an estavelle, how should I map the intermittent connected stream, as it can be an input as an output of the estavelle? Should I map the stream in one way, then remap it the other way, both as intermittent?

Hoping you can enlighten me,
