Venice has co-existed with the sea throughout its 1,500-year history, perhaps better than any other city on earth. Yet over the past century it has flooded increasingly often, as the sea rises and the city itself sinks under its own weight.
We recently published an academic analysis of the various options Venice has to ensure its long-term survival.
Our study compares a range of possible strategies against different degrees of sea-level rise. These include maintaining the current system of mobile barriers, building ring dykes to separate the city from the lagoon in which it sits, enclosing the whole lagoon within a much larger defence system, or – in the most extreme case – relocating much of the city and its population inland.
