Long-term data on shoreline evolution and nourishment operations in the Tarragona coast (Spain, NW Mediterranean) are analyzed. Results show a regional shoreline retreat during the last 20 years in spite of using nourishment to counteract erosion problems. Moreover, under a highly probable scenario of climate change, expected SLR rise will induce additional erosion which may produce the disappearance of some beaches. To assess the sustainability of an adaptation strategy based on the use of beach nourishment we have estimated required volumes for different climate scenarios and existing borrow sediment resources to be considered in a long-term sediment management plan.
