Abstract

This research focuses on the evolution of a block beach into a barrier along a lagoon on the island of São Jorge. The Azores islands are exposed to high wave energy conditions. The geomorphological response of this sector has led to the development of a monitoring program to assess short-term morphological variations and sediment transport dynamics/patterns. To this end, block mobility was monitored in 2022 with the introduction of 30 RFIDs. In the first recovery campaign (2023), 15 blocks were located. The maximum displacement exceeded 25 m with an average of 7.7 m, which varies significantly throughout the analyzed area. The directions of the displacements match the dominant wave regime (W-NW). After these first results, the number of monitored blocks was increased to learn more about the sediment transport process.
