The MOSE project of Venice

The global warming would bring negative influence (e.g. sea level rise) for all over the world, such as flooding in Venice. In fact, floods are common in November and December at Venice, which become a one of most difficult and ongoing problems for Venice. According to data, the citizens who living in Venice would suffer from floods more than 60 times in every year. Rising seas and tides now flood the Venice, thus Italian government began the MOSE project (Experimental Electromechanical Module). The MOSE project could protect the city of Venice and Venetian Lagoon from flooding. The project has been set up at the Lido, Malamocco and Chioggia, which could obstruct sea level rise in Venice during high tides. The MOSE project include 78 mobilizable embankments which has built by Venezia Nuova consortium. The figure shows the theory of MOSE project. 
The Italian government spend more than 54 billion Euro to build MOSE project start with 2003. At the same time, the Venezia Nuova consortium also infuse seawater into deep underneath the surface (700-meter-deep) of Venice. The sandy soil layer (700-meter-deep of Venice) would swell due to seawater, which could lead to surface rising in Venice. Thus, the MOSE project may become a solution of flood in Venice.

However, there are some opponent who believe the MOSE project would bring negative influence to ecological environment in Venice.
