Description :
Grain-size distribution patterns in a point bar system of the Usri River, India, were critically analysed in the light of log-normal, log-hyperbolic and log-skew-Laplace distribution models. Sand samples were collected from the cross-bedding foreset of different sizes of bedform; the aims were to : study whether bedforms heights have any role in grain-size distribution patterns, offer a best-fit statistical model, study the downstream variation of size-sorting in a point bar system, and study the mechanism of grain sorting.
