Abstract: The one-dimensional (1D) Richards equation is used to model infiltration flow in an unsaturated two-layer soil. Imposing continuities of both flux and pressure head at the interface yields a nonlinear equation for determining ...

Abstract: The efficacy of removal and replacement as a mitigation alternative for expansive soil is discussed in view of numerical unsaturated flow/deformation results. Observations with respect to selection of depth and replacement ...
