Abstract

Extreme weather events have significant impacts on coastal human activities and related economy. In this scenario, the forecast of sea storms and sea level alteration in order to mitigate the effects of waves on shores, piers and coastal structures, is a challenging goal. To this end, we investigated the atmospheric pressure drop and sea level increase as a result of 29-30 October 2018 storm event. The dataset used to analyze these phenomena consists of wind-wave numerical modelling and in-situ measurements, validated with National Mareograph Network (RMN) and Tuscan regional wave network. The results of the numerical model give severe wave heights and a pressure drop at the peak of the storm, which produced many coastal damages with coastal defences collapses, loss of property and infrastructure.
