Morphological and sedimentological assessment of submarine dune fields on the coast of Yucatan, Mexico

Abstract: ABSTRACT. Conspicuous sedimentary deposits forming well-structured and prominent submarine dunes are found on the coast of Yucatan (Mexico), close to the ports of Dzilam de Bravo, San Felipe, and El Cuyo. The objective of this study was to evaluate the morphological and sedimentological features of these submarine dunes. Sub-bottom seismologic profiles were obtained and standardized sedimentological analyses were performed on sediment samples collected at the three study sites. Both the height and wavelength o… Show more

“…According to Mendoza et al (2013), the Yucatán coast is more vulnerable to flood than to erosion during the impact of storms. Dzilam de Bravo is characterized by submarine dune fields (Cuevas et al, 2013) that induce a complex nearshore wave transformation. Cuevas et al (2013) characterized the submarine dunes by means of sub-bottom seismological profiles, finding at Dzilam de Bravo a mean dune height ranging from 0.8 to 1.0 m and a mean dune wave length of 98-120 m, predominantly moving northwestward.…”

“…Por su parte, en ELC se reconocen diferencias entre las características sedimentológicas aquí reportadas y lo señalado por Cuevas et al (2013), lo cual es explicable por la diferencia en las temporadas climáticas de las colectas entre estudios, así como por las características de oleaje y orientación de la costa descritas para esa localidad en particular por Appendini et al (2012), reconociéndole como una zona de acumulación de sedimento con características de circulación excepcionales al encontrarse influenciados por la entrada a la Laguna Yalahau al oriente de ELC.…”

“…En el estado de Yucatán, México existen dunas submarinas comúnmente conocidas como 'bajos' o 'blanquizales', que representan ecosistemas en equilibrio dinámico y que se sugiere tienen una función determinante en la protección de la línea costera y los ecosistemas así como de los asentamientos humanos cercanos (Cuevas et al 2013). …”

“…Non-hydrostatic NL-SWE models (e.g., SWASH (Simulating WAves till SHore)) allow us to overcome some of the limitations in classic NL-SWE models by incorporating wave dispersion in the simulations. This numerical approach has been employed for the study of extreme water levels on a fringing reef lagoon (e.g., Torres-Freyermuth et al, 2012), wave run-up on beaches (e.g., Ruju et al, 2014;Guimarao et al, 2015), and infragravity shoreline dissipation (e.g., de Bakker et al, 2014). Furthermore, the potential for the run-up parameterization has been shown in Brinkkemper et al (2013).…”
