Abstract

A sandy beach in the south of Portugal (Faro beach, Ria Formosa) was surveyed from the dune crest seaward to 15 m depth 20 times over a period of 26 months. Wave time-series between surveys were analysed to obtain relationships between wave height and vertical profile variations and to define wave thresholds for important morphological changes. Results show that the active zone of the profile lies between 5 m above and 10.4 m below mean sea level. Based on the pattern of vertical variability, the AA. divided the profile into 4 cross-shore sectors and calculated thresholds for significant wave height generating important morphological changes in each sector
