Multiscale Interactions between Climate and Land Use Change in the Hydrological Dynamics of the Ribeira de Iguape Basin (SP/PR) Supplementary Material This supplementary material provides a detailed overview of the statistical results and graphical outputs used to assess hydrological variability and regime shifts in the Ribeira de Iguape Basin (SP/PR, Brazil). It accompanies the manuscript “Multiscale Interactions between Climate and Land Use Change in the Hydrological Dynamics of the Ribeira de Iguape Basin (SP/PR)”, submitted to Hydrology (MDPI). The document compiles the outcomes of non-parametric statistical tests (Mann–Kendall, Pettitt, SNHT, and Buishand) applied to annual mean, maximum, and minimum streamflow series (1930–2023), provided by ANA and DAEE. It also includes illustrative figures summarizing non-significant series behavior and temporal discharge variability across the basin. The supplementary material is organized as follows: S1. Table S1 – Summary of Detected Breakpoints and TrendsTable S1 presents the results of the Mann–Kendall, Pettitt, SNHT, and Buishand tests applied to the annual mean streamflow series. It lists test statistics, p-values, trend direction, and the detection of significant breakpoints for each station analyzed. S2. Figure S1 – Mean Streamflow SeriesFigure S1 shows the annual mean streamflow values for stations without statistically significant trends, including station IDs 1 (A), 3 (B), 7 (C), 5 (D), 6 (E), 10 (F), and 4 (G). S3. Figure S2 – Maximum Streamflow SeriesFigure S2 illustrates the annual maximum streamflow for stations without significant trends: IDs 1 (A), 3 (B), 7 (C), 2 (D), 6 (E), 10 (F), and 4 (G). S4. Figure S3 – Minimum Streamflow SeriesFigure S3 presents the annual minimum streamflow for stations without significant trends: IDs 1 (A), 3 (B), 7 (C), 6 (D), 10 (E), and 4 (F).
