The Mediterranean is a micro-tidal sea, where storms may hit the coast over several hours or longer, and not only during high tides . Projected changes of winds, storms and waves are small, and confidence in these changes is limited by the quality of climate models applied to the Mediterranean . Overall, sea level rise is projected to increase the risk of coastal flooding despite the potential slight reductions of marine storms  . Risks of erosion and flooding will be amplified with climate change, particularly in river deltas , on low-lying floodplains, on sandy beaches around the basin and in many coastal cities . Impacts are projected to increase nonlinearly during the 21st century with higher sea level rise, because coastal flooding will progressively change from overtopping to overflow, high-tide flooding and ultimately permanent flooding and shoreline retreat  . These risks may be amplified further in areas with poor storm water management and sealed urban surfaces .
