Abstract

ABSTRACT Tereszkiewicz, P.; McKinney, N., and Meyer-Arendt, K.J., 2018. Groins along the northern Yucatan coast. Coastal erosion is a global issue, putting increasing physical and socioeconomic stresses on coastal communities. While shoreline protection structures are typically seen as potential solutions, negative environmental impacts often result. Groins, a shore-normal type of structure, can successfully impound sediment; however, improper design can lead to downdrift erosion and create hazardous rip currents. Widespread construction of groins on the northern coast of the Yucatan Peninsula is thought to have caused significant morphologic change to the shoreline, raising questions as to their effectiveness. The objective of this regional survey was to collect geodata on shoreline position and existing shoreline protection structures. Methods included (1) GPS mapping of the shoreline and groin structures along a 13-km stretch of coastline; (2) developing a classification for groin construction, conditi...
