A study of global sand seas

TL;DR: In this article, the authors propose a method to solve the problem of "uniformity" and "unweighting" of the problem: this article...,..

TL;DR: In this paper, the deformation of crescentic-shaped dunes was investigated under alternating water flow, and new deformation features in addition to rear slipfaces were observed. But the results were in agreement with those of Fenton et al. [Fenton, L.K., Toigo, A.D., Richardson, M.I., 2005.

TL;DR: In this paper, the authors analyzed a dark erg on Mars that could be considered a mega-dune (draa) where secondary dunes of different morphology are superposed over a main crescent-shaped bedform (primary dune).

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.
