Cluster analysis use for processing of the results of suspension's grain composition occurring in rainfall and snowfall

Abstract

Grain composition of suspensions was determined in precipitation samples collected at five sites in the Upper and Lower Silesia region (southern and south-western Poland) over a period of three years (2003-2005). Laser diffraction particle size analyzer was used in this study. Variety of probability density distribution functions of particles size in snow and rain waters obtained during analysis suggests the necessity of further research in order to systematize the data. Cluster analysis was used to this purpose. Research, presented in this paper, was conducted within the Research Project of Polish State Committee for Scientific Research 3 PO4 GO5125 “Application of the laser diffraction particle size analyzer to monitoring the surface waters”.
