Venice is sinking

Integrated solution for a complex system km 2 of salt marshes reconstructed 40 km of industrial canals secured and 7 former dumps confined 100 km of urban shores raised and reinforced 4 mobile barriers realized (85%) to defend from floods km of new beaches and 12 km of coastal dunes rebuilded Control and management Made in Italy know-how 567

Sea level rise and Mose barrier operation Mose will carry out its protective action for a growing number of ordinary and exceptional storm surges. With a 30 cm sea level rise there could be flooding storms (at present 5 storms per year). The risk of extreme events, will increase of 8 times and return period will be reduced from 250 to 30 years only. The number of complete closures will be limited to 30%, thanks to the flexibility of the Mose system by the use of partial closures. The environmental effects of the closures will remain limited, given the short duration of 4 hours and the season of the year with cold windy weather and therefore low risk of anoxia in comparison with the usual three day neap tide stagnation occurring all over the year. The effects on port traffic will be limited by the redirection of traffic through the Malamocco locks
