Studies were conducted to determine the salinity profiles in a freshwater layer stored over saline water in ground-water aquifers. The one-dimensional difusion equation was taken as the governing equation and the diffusion coefficient was assumed to be dependent upon concentration. Using this experimental data, the functional form of the diffusion coefficient was determined. An implicit finite difference solution was used to solve the nonlinear diffusion equation. The solution has been used to determine the salinity profiles in the freshwater layer.
