The case study regards about 70 km long southern Adriatic coast of Apulia (Italy). Shoreline retreat has affected the economy of the tourism activities as well as forced environmental changes in lagoons and coastal moist areas. The study was carried out using field surveys and interpretation of map, orthophots and satellite images. Shoreline mobility changes in space and in time are stressed. Mean shoreline retreats of 10 (±5) m from the late 1940s to the late 1980s, and of 5 (±2.5) m from the late 1980s to the early 2010s have been estimated. Retreats up to 50 (±10) m have affected portions of beach of tens of meters long and particularly prone to erosion. A pocket beach was in dynamic equilibrium over the last twenty years and most likely progradated over the last six decades. The collected data allow for the determination of changes in the possible main cause of erosion occurred in the early 1990s. In view of climatic changes, the economic relevance of the coast for the tourism industry, the importance of several habitats and the uncertainty about the magnitude of erosion processes make the development of tools for the integrated management of the coastal zone an engaging challenge

Medium-term Erosion Processes of South Adriatic Beaches (Apulia, Italy)

The case study regards about 70 km long southern Adriatic coast of Apulia (Italy).
