Abstract
Stability of an unsaturated soil slope under rainfall is usually assessed by a combined numerical
seepage and slope stability analysis. However, such analysis may not be possible in practice due to time and
cost constraints. In this paper, a practical framework that consists of simplified infiltration analysis and slope
stability analysis using explicit equations is presented. The analysis only requires easily determined parameters (e.g., saturated permeability, soil porosity, initial and final degree of saturation) and the total cohesion approach. Application of the practical framework is illustrated by reanalysing slope stability problems that have
been solved by numerical methods.
