Granulometry of Mangrove Sediments

Abstract

The grain size analyses of estuarine sediments give an idea of the depositional environment in the estuaries. Values of graphic mean size, median, standard deviation, kurtosis and skewness are determined from the cumulative curves drawn by plotting size values. The statistical size parameters of the Sunderbans estuarine sediments indicate that the estuarine banks, flanks of the mid channel bars and point bars where depositional energy is low, are characterised by muddy sediments.
