AB Geomorphologic information, topographic maps(dated 1967), aerial photographs (dated 1999 and 2008), andspatial analysis procedures were used to investigate a 90 kmlong coastal sector in South Sicily (Italy). Information wasobtained on coastal erosion/accretion areas, general sedimentcirculation pattern and littoral cell distribution. Human-madestructures and natural headlands constituted important artificiallimits dividing littoral in morphological cells. Ports andharbours were observed at Scoglitti, Punta Secca, Marina diRagusa, Donnalucata and Pozzallo. Most of them worked as“transit” limits which interrupted predominant, eastward directedsedimentary transport, this way generating accretion inupdrift (west) side of mentioned structures and erosion indowndrift (east) side. During the 1967–2008 period, about62,000 m2 and 42,000 m2 of beach surface were respectivelyformed updrift of Scoglitti and Donnalucata ports. The constructionof Pozzallo port gave rise to the formation of a“convergent” limit which favoured large accretion(94,000 m2) east of port structure. Most important naturalstructures were observed at Punta Zafaglione, P. Braccettoand Cava d’Aliga. The knowledge of littoral cell distributionacquires a great importance for appropriate management ofcoastal erosion processes which may be mitigated installingby-passing systems in ports and harbours and carrying outnourishment works in eroding areas, often located downdriftof ports and harbours (when these structures work as transitlimits) and in central part of littoral cells (when these structureswork as convergent limits).
