abstract = {Many attempts have been made to characterize particle size
distribution (PSD) curves using different mathematical
models, which are primarily used as a basis for estimating
soil hydraulic properties. The principle step in using soil
PSD to predict soil hydraulic properties is determining an
accurate and continuous curve for PSD. So far, the
characteristics of the PSD models, their fitting accuracy,
and the effects of their parameters on the shape and
position of PSD curves have not been investigated. In this
study all developed PSD models, their characteristics,
behavior of their parameters, and their fitting capability
to the UNSODA database soil samples were investigated.
Results showed that beerkan estimation of soil transfer
(BEST), two and three parameter Weibull, Rosin and Rammler
(1 and 2), unimodal and bimodal Fredlund, and van Genuchten
models were flexible over the entire range of soil PSD.
Correspondingly, the BEST, two and three parameter Weibull,
Rosin and Rammler (1 and 2), hyperbolic and offset
renormalized log-normal models possessed a high fitting
capability over the entire range of PSD. The few parameters
of the BEST, Rosin and Rammler (1 and 2), and two parameter
Weibull models provides ease of use in soil physics and
mechanics research. Thus, they are seemingly fit with
acceptable accuracy in predicting the PSD curve. Although
the fractal models have physical and mathematical basis,
they do not have the adequate flexibility to contribute a
description of the PSD curve. Different aspects of the PSD
models should be considered in selecting a model to describe
a soil PSD.},
