Venice flood barriers tested for first time

13 October 2013 Last updated at 00:38 BST

Mobile flood barriers designed to protect the Italian city of Venice from flooding during high tides have been tested for the first time.

Four large floodgates rose out of the water creating a temporary sea barrier.

Once the project is completed, the floodgates will extend for more than a mile, blocking the three inlets to the lagoon in the event of rising sea levels and winter storms.
