Fig. 3. Estimated and fitted distributions for selected particle-size data. In each plot, the solid line is the estimate 
given by Eq. [4] and the dashed line is the fitted distribution P defined by Eq. [8]. The circles are the measured particle-size data, with the three filled circles in each plot corresponding to the values used as input in Eq. [4]: cl, cl + si, and cl + si + fvfs. Table 1 contains parameter and goodness-of-fit values for each plot. cl, clay fraction; fvfs, fine plus very fine sand fraction; si, silt fraction.
