AB  - The stability of cut slopes is greatly influenced by seasonal pore water pressure variations underthe combined effect of rainfall and vegetation. However, predicting soil-atmosphere interactionis not straightforward, due to the complexity of both the boundary conditions involved and thehydro-mechanical behaviour of soils, which is coupled and highly nonlinear, rendering the use ofnumerical tools, such as finite element analysis, necessary. The paper discusses the numericalmodelling of soil-atmosphere interaction and presents the analysis of a slope cut in London clayin a highly vegetated area. The whole life cycle of the slope is considered with phases of lowand high water demand vegetation and vegetation clearance. The analysis results indicate thatdense vegetation is associated with high factors of safety, but may induce large differentialdisplacements which are likely to affect the serviceability of the slope. Vegetation clearance,however, may initiate instability, highlighting the need for effective vegetation management inorder to achieve a balance between serviceability and ultimate limit states. Although the caseconsidered is representative of South East England, it introduces the necessary tools forrealistic numerical analysis of soil-atmosphere interaction.
