Survey data from return visits to a linear dune in the Namib Desert provide information about change in dune form over a decade. The data demonstrate that, although change on these large features is slow, there is none the less considerable movement
This paper reports a study of surface change on a large, complex linear dune in the Namib Desert. The dune surface responds to a markedly seasonal wind regime. Despite relatively high levels of activity, especially at the dune crest
