The impact of operating the mobile barriers in Venice (MOSE) under climate change

Results show that the barriers will be able to keep the water level below the safeguarding level of 110 cm nearly all of the time if SLR does not exceed 50 cm. However, with a SLR of 50 cm the barriers will be closed on average once a day, and with a SLR of 75 cm the lagoon will be on average more hours closed than open. The flux reduction at the inlets are quite moderate (10 % for a SLR of 50 cm). Finally, partial closures are shown to be ineffective for the flood defense of the city and only a complete closure will guarantee a noticeable reduction of the water levels in the lagoon.
