Can Moses Save Venice?

Is the $7 billion project to save the coastal city from rising waters working?

Global warming, climate change or whatever you wish to call the syndrome that is causing polar ice to melt and sea levels to rise are of concern to the world's low-lying coastal cities. These concerns are particularly urgent in magnificent Venice every winter with its rains. MOSES (Modulo Sperimentale Elettromeccanico) is a massive (and massively controversial) $7 billion engineering project begun in 2003 to construct 79 movable underwater gates designed to regulate the tidal flows in the city's lagoon (right) to prevent flooding and yet allow large cruise and container ships to pass through.

Venice, founded in the fifth century, rose to be Europe's leading maritime power and center of Renaissance art and architecture, is a UNESCO World Heritage site.

Tourist interests and architectural preservationists are pro-MOSES. Environmentalists continue to oppose it because they are concerned with with a closed system of stagnant water with prevented from flushing out the Venice lagoon. Several months ago, contractjournal.com reported that the mile-long rock and concrete system has caused a new coral reef to form and species previously unseen there to find habitat there. These include the endangered giant pen shell (Pinna Nobilis), an endangered bivalve that can grow to about a yard long and the Dustbin Lid jellyfish (Rhizostome Octopus), the largest in the Mediterranean.
