Flickr photo of the day: High water in Venice
The Grand Canal is busy with waterbuses, water taxis and gondolas. In this photo by Therese Trinko, taken in the late afternoon from the Rialto Bridge in Venice, it depicts a scene that would be familiar to Canaletto and Giovanni Bellini.
The city of Venice, now threatened by subsidence (buildings sinking very slowly into the Venetian lagoon) and a rising sea level, is taking measures against this threat. The MOSE project, now under construction, is a fantastically complicated barrier of 79 separate 300-ton submerged flaps that will be raised to keep the Adriatic Sea at bay at times of extremely high tides.
