Nearly 30% of all surface soils in Australia can be classified as expansive. These soils shrink or swell due to changes in moisture content between dry and wet seasons and result in ground movement. Such movements can apply substantial additional stresses to shallow-depth structures like pavements, lightweight buildings, pipelines and other underground utilities. The situation is expected to worsen due to climate change. To ensure structures designed today last their design life and to develop climate-resilient infrastructure, it is important to understand the interactions at the soil-vegetation-atmospheric boundary and how they contribute to ground movement. Numerical simulations can be very effective tools in such situations. This paper discusses an approach for modelling the soil-atmosphere-vegetation interaction and some related challenges. Interactions at an instrumented research site in South Australia were modelled under current and future climate scenarios (years 2050 and 2090). The observations from and limitations of the modelling strategy are highlighted.
