Análisis morfológico de las dunas primarias costeras y definición de los parámetros controladores de su forma de equilibrio

Abstract

The morphology of equilibrium foredunes profile was evaluated in this thesis. The results indicated that the size of foredunes vary significantly, however their shape is quite constant. Their morphometric parameters volume, height, width and maximum slope are highly correlated, allowing the proposition of equations (allometric relationships). Marine and wind dynamics were evaluated to determine the parameters that control the foredune equilibrium morphology: its size is related to the aeolian sediment drift potential and marine dynamic, while its location depends on the marine dynamics. Based on these results a long-term functioning model was proposed. This model explains different morphological characteristics of the foredunes in equilibrium as a function of the joint action of the marine and wind dynamics. Finally, an equilibrium foredune profile model was proposed.
