Determination of Wadell's sphericity of sediment grains in comparison with granulometric circularity measure
Present research in progress is a continuation of our recent studies on morphological granulometric analysis of sediment images (Balagurunathan et al., 2001) and of real siliceous and calcareous estuarine and marine sediments (Frančišković-Bilinski et al., 2003). The possibility of using image-based granulometries, not yet widely used in the earth sciences was presented to characterize granulometric composition of unconsolidated estuarine and marine sediments. Digital imaging could be also used as one of the methods to characterize grain shape by granulometric circularity measure, as an alternative to Wadell's sphericity. This parameter gives an important information on the history of formation and transportation of clastic sediments. The variation of such measure is studied along different streams.
