This study presents a preliminary assessment of its potential presence along the Galician coast, based on fieldwork, sedimentological analysis of aeolian levels, and photointerpretation of aerial imagery. Fieldwork was conducted in two sectors: Monte Branco - A Barra (Anllóns River estuary, Ponteceso) and Seiras - Porto Nadelas (Porto do Son). Sediment samples were obtained at different depths for subsequent sedimentological analysis (granulometry, morphometry, loss on ignition, biogenic carbonate content, and pH). Sampling locations were selected using aerial imagery (from 1956 to 2023), identifying the different evolutionary phases of aeolian levels since the mid-20th century. The results obtained enable the define geomorphological parameters and methodologies for the identification of HIC 2150*, develop a preliminary estimate of its potential occurrence on the Galician coast, and evaluation of its implications for the management and planning of coastal systems.spaDerechos de autor 2026 Congresos UEx.
