Even since the 14th century, Italian +engineers have dreamed of ways to control the water. Now +a solution may be at hand: the Moses project, a vast series +of sea gates that may finally the sodden city dry. + +The need for Venetian water control has never been greater. +Especially high tides have caused major floods 10 times in +the past 67 years alone, most diastrously in 1966 when the +water in parts of the city climbed to more than 1.83 m. +Compression of sediment under the city, along with rising sea +levels, often causes smaller floods, shutting down businesses +and making sidewalks and squares impossible. + +The source of the problem is geography. Venice is primarily a +small cluster of interlocked islands set in the northern end of +a 536-sq.-km lagoon. A long ridge of land seperates the lagoon +from the far larger Gulf of Venice except at three major inlets. +These openings allow high gulf tides to become high Venetian tides, +with the water sometimes climbing far enough to swamp the city's +seawalls. + +In 1984 a commission composed of Italy's 50 largest engeneering and +construction firms was formed to find a way to control the water +flow through the inlets, and Moses is it. Moses, an acronym for the +plan's technical name as well as a lyrical reference to the parting of +the Red Sea, calls for 78 hollow sea gates---each up to 5 m thick, 20 m +wide and 27.5 m long---to be hinged to foundations, or caissons, in the +seabed and to lie flat there. The gates would usually be filled with +water, but when tides rises to a height of 1 m or more, compressse air +would pump the water out. The free end of the gates would then float +upwards, breaking the surface after about 30 minutes and sealing off +the inlets. Sea locks would permit permit ships to pass while the gates +are up. + +The project---which would take as long as ten years and cost at least +\$2.7 billion---could still run into obstacles, especially given the +fickle nature of Italian politics. Concerned that gates would be raised +so frequently and remain there so long that they would cause water in the +lagoon to grow stagnant, Greens are making that argument in an +environmental-impact review that could delay or even scuttle construction. +Even so, this is the closest Venice has come to a permanent solution to +its water problems in 700 years. By local bureaucratic standards, that's +not too bad. + +%---By Jeffrey Kluger. Reported by Jeff Israely/Rome---Time, June 2, 2003 +\end{document} |
