The medieval city of Venice is situated in the heart of a lagoon on the coast of northeast Italy. It was built on a large area of low-lying marshland. A system of wooden poles driven into the soft mud created an underwater forest. It still forms the foundations of the city we see today. For centuries the City has had to battle with ‘aqua alta’ or high tides from the Adriatic sea. And the gradual combination of water erosion and rising sea levels means the City is now facing a more urgent battle to stay afloat. In recent years a series of barriers which sit on the sea floor and which are raised when an ‘aqua alta’ is expected have been successful in keeping the majority of the city dry. But its already been acknowledged that the Mose Barrier, as it’s known, is not a permanent solution for the future. An idea designed to complement the Mose Barrier, one which was suggested more than a decade ago, is to inject seawater into wells underneath the city. The scientists behind the project are confident that
