  • 摘要:This paper presents the results of an update of the Andalusian shoreline data model with inclusion of the concept of ‘accommodation space’. This variable, together with the erosion rates, is essential for understanding the current dynamics and future evolution of Andalusian beaches. The results calculated for the 2013 shoreline (extracted from the 2013 orthophoto, IECA Institute of Statistics and Cartography of Andalusia) show how 40% of Andalusian beaches do not have accommodation space, mainly due to occupation of such space by urban development and the existence of cliffs. Conversely, 60% of Andalusian beaches do have accommodation space, allowing regression of the shoreline and hence adjustment of the beach to erosion and flooding processes. About 85% of those spaces are situated on the Atlantic façade, where they attain great length, mainly due to less anthropic pressure and the presence of protected natural areas which have prevented their intense occupation. The beaches on the Mediterranean façade have the smallest accommodation spaces and are consequently more vulnerable to flooding or erosion processes, including, in some cases, higher risk of disappearance in the future.
