ABSTRACTImpacts in reshaping coastlines as a result of sea level rise and changes in wave climate are assessed in this paper. The methodology proposed combine SWAN and SWASH wave models to resolve the wave processes at deep water area up to the swash zone in a beach shoreline (Cala Millor, Mallorca, Western Mediterranean). In a first step, the modelling approach was validated with observations obtained during a field experiment that included shallow wave gauges and a video system providing coastline data. Then, the modelling system was applied to two different climate scenarios (rcp 4.5 and rcp 8.5). Projections of mean sea level rise by 2100 were retrieved from state of the art regional estimates, while wave projections were obtained from regional climate models. Changes in the coast were explored under both mean and extreme wave regime conditions. Our results indicate that the coastline migration in Cala Millor beach shows a loss among 5% and 10% of aerial beach. As a consequence, a loss in biodiversity in the native species (especially in Posidonia oceanica), in the beach user comfortability and in the tourism economy is anticipated.
