Abstract
We present a simple one-dimensional model to describe the evolution of a
transverse dune field. The model is characterized by the distances
between the dunes and their heights, which determine the inter-dune sand
flux. The model reproduces the observation that the dunes in a given
field have approximately all the same height. We find that this result
is independent on the initial configuration of the field, as well as on
coalescence effects between migrating dunes. The time for the final
state to be reached is studied as a function of the relevant
phenomenological parameters. (C) 2003 Elsevier B.V. All rights reserved.
