A cross-correlation analysis is conducted to determine the impacts of the heterogeneity of hydraulic conductivity K-s, soil cohesion c' and soil friction angle (tan phi') on the uncertainty of slope stability in time and space during rainfall. We find the relative importance of tan phi' and c' depends on the effective stress. While the sensitivity of the stability to the variability of K-s, is small, the large coefficient of variation of Ks may exacerbate the variability of pore-water pressure. Therefore, characterizing the heterogeneity of hydraulic properties and pore-water distribution in the field is critical to the stability analysis. (C) 2017 Elsevier Ltd. All rights reserved.
