RT Journal Article T1 Fases de crecimiento y estructura interna de una duna costera en regeneración (Reserva de la Biosfera de Urdaibai, País Vasco) T1 Formation and internal structure of a regenerated coastal sand dune (Biosphere Reserve of Urdaibai, Basque Country) A1 Iriarte, Eneko A1 Monge Ganuzas, M. A1 Cearreta, Alejandro AB During a 3 year sand-dune regeneration project in the Laida beach (Biosphere Reserve of Urdaibai) both dune formation process and sedimentary features have been monitorized. The measured bimodal wind regime controls both the formation of bipolar sedimentary structures at different scales and the growth of the sand dune. Main depositional and erosiona! processes controlling sand dune development and the preserved internal sedimentary structures are shown in this paper PB Sociedad Geológica de España YR 2004 FD 2004 LK http://hdl.handle.net/10272/8938 UL http://hdl.handle.net/10272/8938 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 30 may 2026
