Abstract: | Contaminant transport in the upper layers of soil during the multiple cycles of short infiltration and prolonged redistribution
is investigated. Analytical solutions for the two typical problems encountered in agricultural engineering are derived. The
first problem considers the penetration of fertilizer initially applied at the soil surface. The second one is the propagation
of contaminant injected with the applied water. Explicit analytical expressions for the solute concentration are obtained
under assumptions of one-dimensional gravitational flow and advective solute transport under equilibrium conditions. The properties
of the solute penetration are analyzed for the case of contaminant initially applied at the soil surface and picked up by
the water flow during ten infiltration–redistribution cycles.
