Basin=detention requires/implies intermittent=yes?

Good idea! … I could have thought of that too :thinking:
At the moment we have a total of 183 relations, 19.040 ways and 19 nodes with basin=detention. Of these:

  • 9.000+ with intermittent=yes
  • 200+ with intermittent=no
  • 40+ with seasonal=yes
  • 2 with seasonal=no
  • 30+ with intermittent and seasonal Tag
  • 29 with intermittent=yes and seasonal=yes Tag
  • 2 with intermittent=yes and seasonal=no Tag
  • 9.800+ with no intermittent and no seasonal Tag

If neither intermittent=* nor seasonal=* is tagged, then intermittent=yes is implied because that is the (numerically) normal case and corresponds to the definition “The basin is normally not filled with water”?
Otherwise is intermittent=no or seasonal=* required?
