Abstract
In the present work, we use dune modeling in order to investigate the
evolution of transverse dunes in the presence of vegetation. The
vegetation is allowed to grow up to a maximum height H-max with a growth
rate R that oscillates in time. We find that the presence of the
vegetation establishes a maximum height for the transverse duties. If
the transverse dune is larger than this maximum size, then the
vegetation traps a considerable amount of sand, leading to the formation
of vegetation marks at the upwind side of the dune. We also investigate
the formation of the transverse dune fields from a flat sand beach under
saturated sand flux and vegetation growth. We find that the behavior of
the field is determined by the maximum height, H-max, of the vegetation
cover. (C) 2009 Elsevier B.V. All rights reserved.
