Understanding the sensitivity of tidal flats to environmental changes is challenging. Currently, most studies rely on process-based models systematically explain morphodynamic evolution flats. In this study, we proposed an alternative empirical approach explore flat dynamics using statistical indices based long-term time series daily surface elevation development. Surface dynamic (SED) focus magnitude and period changes, while signature (MDS) relate sediment drivers. The analyses were applied intervention site in Netherlands determine effect recently constructed groynes flat. Using these analyses, able (1) detect a reduction SED (2) that predominantly caused by wave impact between rather than currents. Overall, presented results showed combination novel provides new insights into trajectories flats, ecosystem functioning, physical drivers (wind tides). Finally, suggested how MDS may help future climate resilience intertidal habitats.
