Ojeda Zújar J., Malvarez García G., Vallejo Villalta I. Morphometric Evolution of the Active Dunes System of the Doñana National Park, Southern Spain (1977-1999). Journal of Coastal Research. 2005; 49: 40-45.

Abstract

Initial results of the morphometric evolution analyses of the active dunes system of the Doñana National Park are presented, emphasizing the volumetric changes occurred between 1977 and 1999. The use of photogrammetric restitution of the imagery from both dates, generation and analyses of DEM’s, and quantification and mapping in a GIS, enabled a calculation of the volume of the entire active dunes, as well as the estimation of advance rates, areal changes and sedimentary balance for a pilot area. In this instance, results illustrate the slowing-down of the advance rates of the slip faces, the areal enlargement of the slacks and the narrowing of the transverse ridges which produces a change in the cross-sectional profile of these, also indicated in the volumetric changes of the pilot area
