Venice, Italy, is sinking. The city spent about $6 billion on MOSE – a mobile floodgate system that rises to separate the Venetian lagoon from the Adriatic Sea, blocking high tides from inundating the city. But that might not be enough. Fifty years ago, the lowest point in Venice, St. Mark’s Square, only flooded forty times a year. Now, it floods 250 times a year.

From pumping water into the city to super levees, WSJ asked an expert to explain potential engineering solutions to protect the “floating city” from being overrun by water.
