Abstract
Souza et al. (2022) based on grain size analyses, Optical Stimulated Luminescence (OSL) ages in fluvial sediments, and regional topography affirmed that most of the Paraiba do Sul River Delta (PSRD) has been deposited during the Little Ice Age (LIA). Souza et al. (2022) also inferred that after the LIA, PSRD presents shoreline erosion, using OSL undetermined results, regional topography, and field photographs, suggesting the direct connection of erosion and human intervention along river basin. As the results obtained by Souza et al. (2022) present several inconsistences about coastal evolution, and question previous works about PDRD developed in the last 30 years, we discuss these in three different sections, covering geological, historical, and recent geomorphological changes in PDRD.
