Sandy beaches are complex, highly dynamic, fragile environments that constantly evolving. Understanding the dynamics of these areas is crucial, both for fundamental science and coastal zone management.

A 15 topographic profiles were surveyed perpendicular to coastline during three field campaigns between September 2019 July 2020. The indicate morphodynamic equilibrium beaches, characterized by normal cycle with erosion winter accretion summer. balance primarily attributed physical behavior response wave energy, as well presence developed dune capable supplying sediment periods shortage. Additionally, from 90 samples clearly highlights significance hydrodynamic factors, such waves, tides, currents, littoral drift, winds, distribution sediments on Massa beaches. Atlantic waves NNW sector, accompanied North-South govern transport deposition along while local winds contribute their redistribution across different beach zones (foreshore, backshore, dune). Indeed, conditions, proximity or distance source zones, play critical role providing valuable insights management strategies aimed at mitigating erosion, preserving morphology, ensuring sustainable development zones.
