ABSTRACT: This paper presents a numerical modelling exercise that investigates the effect of hysteresis of the soil water characteristic curve (SWCC) on an unsaturated slope. Multi-year climate data is applied as a soil-atmosphere boundary condition on a two-dimensional finite element unsaturated slope model. The results obtained for hysteretic and non-hysteretic simulations are analyzed in terms of water balance at ground surface and temporal storage. Detailed slope stability analysis is performed considering the porewater pressures that are obtained from the hysteretic and non-hysteretic simulations. The research will contribute to existing literature and provide a better understanding of the impact of hysteresis in the SWCC on slope stability under an atmospheric boundary condition.
