FIG. 47a. Bedforms with superimposed bedforms migrating in a divergent direction. Dunes with superimposed dunes, Algodones, California; oblique air photograph taken by Gary Kocurek. The main dune at the lower left is migrating from right to left; the dunes superimposed on its lee slope are migrating toward the viewer, a divergence of 90 degrees, as simulated in Figure 46D-N. At other locations, such as where indicated by the arrow, the divergence is roughly 45 degrees, as simulated in Figure 46A. The height of the main dunes is approximately 10-20 m.
