Abstract

Valdevaqueros dune is located in one of the windiest points of Europe. The high dune mobility and the frequent occurrence of strong east winds have caused a serious problem of a massive and continuous sand invasion over a regional road towards the village of Punta Paloma (Tarifa). Despite the existence of various formulations to compute aeolian sand drift power, they seem not to fit with the actual situation of Valdevaqueros. To determine real transport rates in Valdevaqueros dune system, an anemometer tower and a hand-made sand trap have been placed to retain the drift sands at different heights or levels. The in-situ average transport rate for moderate wind power has been up to3 times higher than the theoretical computation. Grain-size results have been of great help for the understanding of the sand grain distribution at different heights.
