ON USING THE LOG-HYPERBOLIC DISTRIBUTION TO DESCRIBE THE TEXTURAL CHARACTERISTICS OF EOLIAN SEDIMENTS

Abstract

ABSTP~CT: Following the early work of Bagnold (1941) h has recently been suggested that the log-hyperbolic distribution offers a better description of grain-size distribution than the log-normal distribution. This paper undertakes a comparison of the suitability of the log-hyperbolic and log-normal distributions in describing the textural characteristics of desert-dune sediments. A statistical analysis of the results shows that no apparent gain is obtained when using the parameters of the log-hyperbolic distribution to describe such sediments.
