An approximate analytical solution is presented for steady flow of salt through soil with a nonuniform distribution of the water content. The solution is in good agreement with a numerical computer solution, provided by the CSMP simulation language. Both solutions also agree with the analytical solution for soils with a uniform distribution of the water content. It is shown that effluent curves from soil profiles, with the same average water content and leached at the same steady rate, are basically the same and thus independent of the variation of the water content in such profiles.
