%X Located in Tarifa, near the Strait of Gibraltar, the
migration of Valdevaqueros dune was controlled by
sand extractions for building purpose. As the Spanish
Shore Act was approved in 1988, the sale of sand was
forbidden and the dune started to move forward,
burying the leeward pine wood and the only road to
Maspalomas village.
Consequently, six topographic levellings have been
taken during the last eleven years. Sedimentary
granulometries and meteorological features were taken
into account. D50 values have been calculated for dune
foot, windward and dune top. Wind speed threshold is
estimated above 15 km/h. East winds are responsible
for dune movement, whose advance rate has reached
very high values (over 18 m/year). Slope and
volumetric changes have been determined, providing a
clearer explanation of the dune evolution
