The barchan "court" (Fig. 23. 1) is kept partly clear of sand by the intensely
turbulent wake in the lee of the slip face (Knott 1979). The turbulence is
generated both by horizontal-axis roll-vortices shed at the brink, and by the
vertical vortices ...

Geomorphology: The Mechanics and Chemistry of Landscapes
Barchan dunes Perhaps the most distinctive is the barchan dune, an isolated
crescentic form with arms that stretch downwind. Barchans are not huge, often
with heights of only a few meters. They are often found in well- organized fields,
and ...

Geological Survey Professional Paper
The wide spread of dips in barchan dunes reflects the curvature of the slipface of
that type of dune. The narrow spread of dips in the transverse-ridge dune
similarly is the result of a relatively straight slipface. Although laminae within

Mechanics of Wind-blown Sand Movements
Responses of barchan dunes to changes of wind direction and to collisions (from
Elbelrhiti et al. 2005) barchans sustain the instability of the next downwind
medium-sized dunes which then release more small-scale dunes (see Fig. 7.9h).
