Table 2 Kolmogorov–Smirnov (KS) test p-values comparing the erratic and persistent regimes; Kruskal–Wallis (KW) test p-values comparing the four empirically classified streamflow regime types, and post-hoc Dunn’s test results showing the number of pairs of streamflow regime types exhibiting significant differences (p-value < 0.05) in catchment characteristics.
