A finite element formulation for flow of fluid in a porous elastic media has been derived from a Gurtin type variational principle. Biot's field equations for porous media have been used in which the constitutive relations include the compressibility of the fluid. It is shown that by proper choice of the form of the compressibility of the fluid as a function of the state variables, this option of formulation can be used to treat the partially saturated soil.
