Perché i Paesi Bassi non hanno costruito diverse dighe sulle isole Frisone invece della diga di Zuidurzee?

You’ve gotta leave something for the kids…
Why did they need to?
The wadden zee is a place to fish
“Afsluidtijk”? Lmao.
I don’t know the exact reason, but there are two reasons I can think of.
The afsluitdijk also functions as a road between Frisia and Holland. Your proposed dam would not serve that purpose.
The Wadden Sea is a unique ecosystem, creating dams between the islands would turn it into fresh water and prevent migration of sea animals and change it completely.
Is Schiermonnikoog really necessary?
would destroy a unique natural habitat: de waddenzee
For ecological (and probably econimocal too) reasons. The Waddenzee is quite a unique ecological system. It’s protected.
Not sure if it was already protected back then. But it would’ve made an ecological catastrophy for the coastlines of Fries;and, North Holland, Groningen and Germany
The sounds in between the islands are comparatively quite deep as opposed to the entry to the Zuiderzee. Especially in between the mainland and the island of Texel, the sound reaches depths of close to 30m, caused by tidal forces. These tidal forces in turn would cause significant erosion, requiring múch more maintenance, and therefore bringing much more costs to any project of the sort. Finally, the idea was with the Afsluitdijk to create essentially one giant ass polder which would then by made dry and usable for large scale agriculture. Only the Noordoostpolder and the two polders that make up the Province of Flevoland were realised of that plan in the end. Every now and then there are still ideas being floated of finishing the poldering of the Zuiderzee/IJsselmeer, but it’s never really made it beyond the realm of political speculation.
The real answer is that all those drainage channels between the islands are really deep and have a lot of erosive presures on them. while the zuiderzee channel was shallow and not directly exposed to the elements because it was sheltered behind the islands
Sand vs clay? The Flevopolder’s purpose was agricultural land, I would imagine the Waddenzee would become a dustbowl..
