Lire la suite >Sediment budget data from an 18-month topographic survey were analysed with data frombrief experiments on wind parameters, beach moisture contents, bedforms and sand mobili-zation in order to monitor conditions and patterns of embryo dune development over a flat150–1000 m wide accreting upper beach. The surface conditions over the upper beach locallyaffect aeolian transport, but net dune development over time depends on sustained strongwinds and their orientation. Incoming marine sand supplied by storms and onshore windsis reorganized by the dominant offshore to longshore winds into elongated embryo dunesover this upper beach, imprinting a regional morphology of long-term longshore dune ridgedevelopment.Lire moins >
