Sedimentary dynamics and erosion on tide-modified mixed beaches in Northeast Brazil

Coastal erosion is a relevant concern along the semi-arid coast of Northeastern Brazil, where tide-modified mixed siliciclastic–carbonate beaches exhibit seasonal variability and increasing anthropogenic pressure. This study aims to analyze the seasonal sedimentary dynamics of Peroba and Picos beaches, located in Icapuí, Ceará. Sediment samples were collected during four field campaigns, in March,…
