During the first year, two different phases of sedimentary development were observed. Semester 7 (autumn and winter) showed a significant sand accumulation (>3500 m3) due to the dominant NW winds that reached an average velocity greater than 4 m/s. On the other hand, semester 2 (spring and summer) exhibited SE-dominant winds with average velocities between 7-2 m/s. Sand deposition was nill during this period. The final result has been the formation of a supratidal area of 6250 m2 with almost 8 m of maximum height (above national ordnance datum) on this sandy estuarine environmentspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Sand-dune regenerationEstuarine environmentBiosphere ReserveUrdaibaiBasque Countryjournal articleopen access
