The work presents the results of a field and numerical study aimed to investigate the resistance and resilience, associated to an artificial shoreline perturbation, on a sandy beach. A temporary groin was deployed on a micro-tidal sea-breeze dominated beach to induce a shoreline perturbation. Wave conditions during the field experiment were highly correlated with sea breeze wind events, inducing a persistent alongshore sediment transport. A new one-line numerical model of beach evolution was calibrated and verified with the field surveys, reproducing both the sediment impoundment and subsequent beach recovery after the groin removal. Thus, the numerical model was able to simulate the mechanisms controlling the growth and decay caused by an artificial perturbation.
