Partially saturated flow in a poroelastic medium
Ralph E. Showalter, Ning Su · Discrete and Continuous Dynamical Systems - B · 2001
The formulation and existence theory is presented for a system modelingdiffusion of a slightly compressible fluid through a partially saturated poroelasticmedium. Nonlinear effects of density, saturation, porosity and permeabilityvariations with pressure are included, and the seepage surface is determined by avariational inequality on the boundary.
