CA model
CA models range from the coarse graining of sand by thinking about clusters of sand grains (sand slabs) rather of person particles. In CA models, the topographic height is taken is the quantity of compiled slabs. The topographic height h(i, j) at site (i, j) inside a two-dimensional field changes as time passes. Previous CA models for aeolian sand dunes used a phenomenological formulation of saltation that’s, it wasn’t according to fluid motion. Although there’s some variation within the formulations of saltation, the prior models determined situational-specific saltation distances, for example defining the jumping length like a purpose of the condition from the sand bed.
