The modelling of particle sizes or grain sizes arises is various disciplines. I describe two such applications, one to data from Petroleum Engineering and the other to data from Sedimentology. Though various distributions have been used for modelling such data including the log-normal and the Weibull, I concentrate on using the log-hyperbolic distribution. The two data sets are accompanied by different modelling issues, the first is collected in a laboratory setting while the second results from the analysis of sediment sampling from river beds, resulting in various measurement errors. The latter is part of a bigger project for characterizing avulsion processes for rivers.
