yup, a much better design that rests on dry land rather than on the sea bed while not in use; reducing corrosion rates and making maintenance a much cheaper procedure. "Ah, but what about the landscape!" cried the politicos when greasing this pork barrel for their industry friends. Yeah, right... I bet they had the same scruples when they broke ground for Pordo Marghera. SMH

  The MOSE consists of 3 separate installations for 3 different harbor mouths, so in principle it wouldn't have been that much different from the Dutch scenario.

    It's actually four sections, each longer than the entire Maeslantkering.

  The Maeslantkering is only one of a series of structures to control the water flow, the Delta Works[1]. The Oosterscheldekering[2] is a much bigger structure, about nine kilometers long with four kilometers of openable sluices that were added after protests against closing off the water way. Similarly gigantic is the 5 kilometers long Haringvlietdam[3]. These projects are quite old, though, so some innovation to water control is always welcome. The system used by MOSE seems to be quite easy to hide compared to the massive steel and concrete structures of the Dutch system. If it turns out there is no penalty to longevity and maintenance, a system similar to the Italian project might just show up in the Netherlands as well.

Venice is a series of islands that is 100% developed. There is no open dry land, aside for a few small (<1 city block) sized parks. https://upload.wikimedia.org/wikipedia/commons/3/38/Venice_as_seen_from_the_air_with_bridge_to_mainland.jpg https://upload.wikimedia.org/wikipedia/commons/3/38/Venice_a...

  Sure but a double-digit amount of the entire Netherlands was water, and remains below sea level. Hence the name. I haven't a clue if it's practical/economical for Venice to build more land, however; without more information, I'll assume their solution is right for them, as the Dutch solution is for the Netherlands.

    Rotterdam was almost completely rebuilt after WWII, Venice has been there almost unchanged for about 15 centuries. It's much more fragile than practically any other city in the World and needs a particular care. Building modern structures on it (choosing carefully where, since it's built on over 400 islands) would ruin it forever.
