A Statistical Analysis of the Occurrences of Critical Waves and Water Levels for the Management of the Operativity of the MoSE System in the Venice Lagoon

The particular structure and configuration of the Venice lagoon represents a paramount case study concerning coastal flooding which affects natural, historical/cultural properties, together with industrial, commercial, economical port activities. In order to defend (and other sites) within from severe floods, Italian Government promoted construction complex hydraulic/maritime system, including movable storm surge barrier named Experimental Electromechanical Module (MoSE), be activated when specific water levels occur. When MoSE barriers are raised, only access for commercial cruise ships is represented by Malamocco lock gate, provided that suitable safety conditions (involving significant wave height) satisfied. addition, has recently established that, in near future, large will always have enter/exit through entrance. turn, navigation (will be) controlled combined MoSE-Malamocco ruled both univariate bivariate paradigms/guidelines. As novelty, present work, first time, statistics heights (both ones) investigated: particular, these variables turn out dependent, their joint occurrence (statistically modeled via Copulas) can determine stop ship navigation, yielding economic losses. Here, Return Periods Failure Probabilities used thoroughly model statistical behavior levels, provide useful quantitative indications management tricky hydraulic, maritime system lagoon.
