Abstract
We investigate beach resistance and resilience by means of field observations and a numerical model. A field experiment was conducted on a sea-breeze dominated and micro-tidal beach located in the northern Yucatan peninsula. A temporary groin was deployed for 24 hours to induced a beach perturbation. Beach surveys were conducted with a high spatial and temporal resolution to investigate the beach resistance to the presence of the groin. Moreover, beach surveys continued after the structure removal to estimate the beach resilience. A numerical model was calibrated with the field observation and was further employed to investigate beach resilience and resistance. Numerical results suggest that diffusion is an important mechanism for beach recovery in the study area.
