Summary: | Closed-form solutions are derived for steady state density-dependent fluid flow and solute transport problems in a one-dimensional vertical soil column. Transport mechanisms considered are advection, molecular diffusion, and velocity-dependent dispersion. Solutions can be obtained for a wide variety of cases. Characteristics of density-dependent solutions, including effects of variations in density and the thickness of transition zones, are investigated for a simple case. Unique features not found in density-independent solutions are observed. Nonuniform concentration profiles with vanishing density effects are also identified |
