Concerns that high tides are becoming more frequent because of climate change have increased the urgency. The system of movable underwater barriers, dubbed Moses, has been beset by corruption, cost overruns and delays. A recent test of the deepest expanse of barriers - at the Malamocco entrance to the lagoon - was declared a success by the New Venice Consortium. The gates can be lifted to create a temporary barrier in high tides. In the 150 years that they have been recording the tide levels in Venice, two high tides above 1.5m have never been recorded in a year.
