Introduction
SEEP/W simulates water transfer in response to spatial variability in elastic and gravitational potential energies. Density-driven flow, also known as free-convection, can be simulated by giving consideration to spatial variations in fluid density. Fluid density affects the gravitational energy. Interpreting the results of a density dependent flow analysis can be challenging. For instance, the pore-fluid pressures and volume based fluid fluxes (L3/t/L2) in a vertical column with steady-state flow are both non-linear if the fluid density is variable. Fluid fluxes are generally assumed constant in the steady-state scenario; however, this assumption is only correct if the fluid density is constant. The purpose of this example is to demonstrate how to interpret these seemingly contradictory results in the context of the mass conservation statement on which SEEP/W is formulated and the governing flow law for a variable density fluid in a porous medium.
