Low-elevation areas along the Mediterranean coastline are at high risk as a result of extreme storm surge events. Coastal flooding is often caused by extreme storm surge events, inducing significant problems on coast populations, infrastructures and environment. Storm surges reveal significant differences between Mediterranean regions, due to the topography, storm magnitude and direction characteristics of each area. Nicholls and Hoozemans (1996) showed that coastal management at Mediterranean region needs to address long-term problems and especially, the impact of climate change on the sea level rise. Conte and Lionello (2013) based on a climate change study covering the period 1951-2050 found that the climate change in the Mediterranean Sea may bring a likely attenuation of storminess. We seek to explore the trends of sea level extremes for a period of 150 years under a future climate scenario (A1B) with highly increasing concentrations of atmospheric greenhouse gases.
