Abstract:
|
Examining grain-size distributions of deposits in rivers is an important component in understanding sediment transport systems. We analyze data obtained from a high-resolution laser analysis of particle sizes in samples obtained from three modern rivers and three ancient rivers. Exploratory data analysis is carried out to examine possible clusters and variation in the empirical distributions of the grain sizes. We next discuss modeling the data using hyperbolic distributions.
