Analysis of overflow and wave overtopping of the Scardovari lagoon levees

This paper studies the Scardovari lagoon (Po Delta, Italy) in relation to the coastal flooding of the low-lying rear area, that is protected by earth levees. The paper aims at identifying the critical stretches, also in view of climate changes. Three different scenarios are investigated considering both the future sea-level rise and the rate of subsidence that affects the area. Field measurements, numerical models and analytical tools are used to define the overflow and wave overtopping. It is found that the critical stretches that require mitigation measures are mainly located in the North-eastern sector.
