Description :
Using the Coral Pink Sand Dunes in southern Utah as a model, this study tests nearest neighbor analysis adapted as a method to objectively identify and characterize differences in two dimensional dune patterns within a dune field and to identify changes in dune patterns over time. Reducing transverse and barchanoid dunes from linear to three-point features in planar space emphasizes the clustering that occurs when dune lengths and wave lengths are more disorganized or random. This clustering may be in response to a system perturbation, such as an influx of sediment, and is reflected in lower nearest neighbor index values.
