Talk:Key:water system

polder = land or canals/ditches ?

@Multimodaal:In the definition of water_system=polder, it is written "Low-lying tract of land enclosed by dikes". But in the use of these tags, nobody put them on the lands but on the waterways (see https://overpass-turbo.eu/s/1rrI). Maybe the definition needs some improvement, no ?

Hi @Krako73: tanks for pointing this out, you are right. Just tried to improve the definition, please feel free to improve the wording yourself as well. Cheers! Multimodaal (talk) 19:58, 12 July 2023 (UTC)

Ok, thanks. I just tried to improve it: I'm not a specialist of polders so feel free to improve it again. Best regards. Krako73 (talk) 14:02, 13 July 2023 (UTC)

Thanks for your contribution. You were right that the first definition focussed to much on the land only (and did not mention) , but actually "polder" is a property that can refer to the water but also the land and also the whole (entire island: water + land in it): one island may be a polder, while the neighbouring island may very well be a boezem. I will revert it to the former version and try to take some of your changes along

Hi @Krako73: , you might like this image from a water board (link) that illustrates the scope of the terms boezem and polder (zee = sea, rivier=river). I asked their permission to use it on the wiki. Cheers Multimodaal (talk) 11:06, 24 July 2023 (UTC)
