• Resumen

  • Promoted by local authorities, a sand-dune regeneration project in the Laida beach (Biosphere Reserve of Urdaibai) started in October 2007. 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 mIs. On the other hand, semester 2 (spring and summer) exhibited SE-dominant winds with average velocities between 7-2 mIs. 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 environment.
