Table 4: Percent area of significant coherence (PASC) between rainfall and coefficients between SWC and topographic or edaphic indicators at different temporal scales (\(<\) 1 year, 1–4 years, and \(>\) 4 years). There are more pronounced differences between coal mining and non-coal mining areas at a depth of 30 cm (Figure 4).
