Beach and Structure Interactions
The Yucatan coast has experienced beach erosion over the past decades. The study area is characterized by intense and persistent northeasterly sea breezes, which drive a net westward littoral transport. Thus, we investigate the morphological effects caused by four detached breakwaters constructed in 2016-2017. The combined use of high-resolution DGPS measurements and DEM derived from UAVs flights allow an assessment of the structures’ performance behind the structure and in adjacent beaches. Seasonal beach variability was more drastic on beaches located behind impermeable structures. However, downdrift erosion was observed in all cases regardless of the structure characteristics and shoreline orientation.
