RT Journal Article T1 Regeneración dunar en la Reserva de la Biosfera de Urdaibai (Bizkaia, País Vasco) T1 Sand-dune regeneration in the Biosphere Reserve of Urdaibai (Biscay, Basque Country) A1 Monge Ganuzas, M. A1 Iriarte, Eneko A1 Cearreta, Alejandro AB Promoted by local authorities, a sand-dune regeneration project in the Laida beach (Biosphere Reserve of Urdaibai) started in October 2001. 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 environment PB Sociedad Geológica de España YR 2003 FD 2003 LK http://hdl.handle.net/10272/9080 UL http://hdl.handle.net/10272/9080 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
