Distinction between dune, beach, and river sands from

Dune sands commonly can be distinguished from beach sands on the basis of such plots. The distinction between the sand types can be numerically stated by computing the third moment (skewness) of the distribution curve. On the phi scale the third moment (skewness) for dune sands is generally positive, whereas that of beach sands is generally
