Fig. 2From: Simple stochastic cellular automaton model for starved beds and implications about formation of sand topographic features in terms of sand fluxCalculated topographies from the oblique view. a Isolated ripples (barchan ripples) and b continuous ripples; shown for the same time (105 steps), with average sand thicknesses of 1.0 and 30, respectively. The movement of particles is from the left to right, and in the graphics, the light is cast from the upper left. The height of one slab is one-tenth the length of one cellBack to article page
