TL;DR: In this article , the authors analyse barchan dunes migration patterns and their effect on urban and agricultural areas in the Ain Salah region in southern Algeria using a supervised classification of Landsat images.

TL;DR: In this paper, a bar on the Brazos River near Calvert, Texas, has been analyzed in order to determine the geologic meaning of certain grain size parameters and to study the behavior of the size fractions with transport.

TL;DR: In this article, a detailed mapping of the sedimentary geology of Saudi Arabia by the Arabian-American Oil Co. (Aramco) began in 1933, and by 1959, exploration parties of one type or another had surveyed more than 1.3 million square kilometers (500,000 square miles).

TL;DR: In this article, the third moment (skewness) of a normal curve is used to distinguish between dune, beach, and river sand, and the difference between the two types of sand types can be numerically stated by computing the third moments of the distribution curve.
