Fig. 1: Schematic representation of hazards for Venice lagoon.

The relation between the sea level and the flooded area as a function of the estimated damages (filled coloured circles). The horizontal dashed-dotted black lines mark significant flooding levels corresponding to the sea level flooding St. Mark’s square (120 cm), the level at which foodbridges are needed to walk across the square (140 cm), and the level at which water will enter the St. Mark’s Basilica (160 cm). The red dashed-dotted line marks the level reached by the 04/11/1966 event known as “Great Flood of Venice" and studied in this work. The inset shows the location of the two tide gauge stations used to evaluate the sea levels within the lagoon (Punta della Salute, yellow circle) and outside (Piattaforma, white circle). The pink circles mark instead the position of the MoSE barriers at the three inlets (Diga Nord, Malamocco, and Diga Sud).
