Cambios morfológicos y sedimentológicos en playas del sur del Golfo de México y del Caribe noroeste

This study aims to compare morphological and sedimentological variations between the beaches of the Southern Gulf of Mexico and the Riviera Maya (Northwest Caribbean) by conducting two regional samplings of foreshore sediments, measuring topographic profiles of the beaches, and analyzing the potential impact of sea level rise from global warming. The time lapse between samplings was 26 and 32 years. Beach profiles, shoreline changes, textural parameters and composition of surficial beach sands from the foreshore were compared. This study considers the state of tide, rainfall and meteorological events. A total of 23 beach locations were studied: 19 for the Southern Gulf of Mexico and 4 for the Riviera Maya. The beach profiles show variations, with recent beaches sometimes being wider than the ancient ones. The concavity of the recent exposed beach profiles suggests that many of them are eroding. The
