Abstract
The transport theory accounting for an abrupt pressure change applied to compressible and variable density fluid in saturated porous media (Sorek 1996), is used to analyze the effects of pressure change on solute migration. The modified balance equations of the solute mass in the porous medium and of the fluid mass and its momentum, during the evolution period when nonlinear wave equations dominates, are solved analytically for a 1-D simplified model. The cases of expansion and compression waves produced by the change of pressure (or pumping/injection rate) are considered. Closed form solutions demonstrate the possibility of considerable solute withdrawal from the upper layer of the porous medium due to the change in pressure or pumping/injection rate.
