The study looked at how beaches and dunes in Menorca Island will be affected by rising sea levels and storm waves. By using advanced computer models, the researchers found that sea level rise is the main factor causing erosion, leading to a 25% increase in erosion by the end of the century. They also discovered that features like the berm on the beach help protect the shoreline from retreat and dune vulnerability. This shows the importance of understanding how beaches change over time to predict and mitigate coastal impacts.
