“…The PCA proves this, where slope and surface roughness were explanatory variables and reduced runoff (Fang et al, 2015; Pires et al, 2006). Vegetation cover is among the important variables for explaining runoff reduction in the rehabilitation stage, which may be due to its interception of rainwater, impeding the water kinetic energy from reaching the ground and thus reducing runoff (Bessi, Dias, & Tonello, 2018; Freitas, Dias, Silva, & Tonello, 2016; Lorenzon, Dias, & Tonello, 2015). The explanation of the components for the variables SD, R, SPD, MSPR, D, Slope, ma, TP, and VC shows that these are the factors with higher importance during the rehabilitation stage of the mines for reducing runoff.…”
