We also note that currently there are particle-size analysers used in Australian laboratories that can provide 10-15 size classes, which allows for a continuous particle-size distribution. However, in order to use this information effectively, we need to parameterise the distribution; a parsimonious yet flexible function that can accommodate multi-modal size distributions is required.
