Deriving the 100-Year Total Water Level around the Coast of Corsica by Combining Trivariate Extreme Value Analysis and Coastal Hydrodynamic Models

As low-lying coastal areas can be impacted by flooding caused dynamic components that are dependent on each other (wind, waves, water levels—tide, atmospheric surge, currents), the analysis of return period a single component is not representative total level at coast. It important to assess joint all components. Based semiparametric multivariate extreme value analysis, we determined probabilities significant wave heights (Hs), wind intensity 10 m above ground (U), and still (SWL) exceeded jointly imposed thresholds along Corsica Island coasts (Mediterranean Sea). We also considered covariate peak direction (Dp), (Tp), (Du). Here, focus providing scenarios populate hydrodynamic models, SWAN SWASH-2DH, in order compute 100-year (100y-TWL) coasts. show how proposed help more accurately define zones potentially exposed flooding, especially where unique 2 was taken into account previous studies. The computed 100y-TWL values between 1 eastern maximum 1.8 western calculated below 2.4 threshold recommended when considering sea rise (SLR). This highlights added performing full integration offshore conditions, together with their dependence simulations for screening out flooding.
