dune in Saudi Arabia while Fenwick (1991)
presented particle-size data from the cross-profile
of a single linear dune at Natab. Livingstone (1987)
provided particle-size data from the Visitors’ Dune
site along with data from eight transects on the two
dunes on either side of Visitors’ Dune. All of these
have demonstrated a general pattern of finer crests
sitting on coarser plinths which has commonly
been attributed to a coarse creep population blown
onto the dunes from the interdunes. Lancaster
(1981, 1989), who included transects close to
Gobabeb, confirmed this observation for the wider
Namib.
