Unless you're being facetious, you might want to read up on things like the Delta Works[1], the Zuidersee Works[2] or the smaller project of Maeslantkering[3].

Unless you're being facetious, you might want to read up on things like the Delta Works[1], the Zuidersee Works[2] or the smaller project of Maeslantkering[3]. If there's one country that has had long experience in dealing with the threat from the oceans, it's the Netherlands. And these kinds of projects don't really lend themselves to organizations that require profit for their investments. (I'm not dutch, but I have biked across the 32 km long causeway of Afsluitdijk[4] and parts of the Delta Works.)
