Application of diffusion-advection equations to in-field monitoring of soil suction profiles

Structures built on expansive soils are susceptible to damage arising from the shrink-swell behaviour of soils. Due to this issue and the limitations of the existing methods that estimate displacement demand on structures, a new diffusion–advection equation that adequately models the variation of soil suction, responsible for shrink-swell movements has been proposed. A numerical scheme in MATLAB code has been presented in the paper. To validate...
