The outcome of the cluster analysis of all measured variables
resulted also in the formation of two clusters C1 and C2, in which
C1 is divided in two sub-clusters C1-1 and C2-2 (Fig. 3). Thereby,
C1 contains the majority of the studied variables. It summarizes
variables of groups 2–4 of descriptive statistics, stated as drivers
of erosion processes and entries from the tributaries Mulde and
Saale in Table 1. C2 includes B, U and Cl. This is comparable to
the group 1 – dilution derived from Table 1.
One element from each group of Table 1 was selected
exemplarily for display of the variation of element proportions in
sub-fractions (particulate,
