I'm following this thread since the beginning. I'm interested in
intermittent river for Madagascar
(http://osm.org/go/lrsj4--?relation=447325). There is mostly a dry
season and a wet/rainy season from December to April. There is also
around 3 cyclones a year.
Some rivers (or part of river) or lakes are permanent.
Some rivers are seasonal and only filled during rainy.
Some rivers, especially in the semi-arid South, are only active after
cyclone or heavy storm.
One may also not that road are also subject to intermittent
(un)usability. Some unpaved one are closed during rainy season. Some
part of road have concrete parts that are flood_prone during cyclone.
> Less work if intermittent is simply used without the frequency extension
.. thus:
intermittent=yes/no/winter/spring/summer/autum/seasonal/ephemeral (default assumption of
"no")
I like this proposal. One may extend it to lakes. How can we (or not)
extend it to roads?
Indeed, winter/spring/summer/autum/ does not apply to Madagascar. One
may define cold/fresh season (May-August), hot season (September,
December) and wet/rainy season (January-April). Or on the East Cost,
only two seasons: the wet one and the rainy one ;-)
