Abstract
Two analytical solutions are presented for a problem of solute transport in transient flow in an unconfined aquifer. The source of the solute is a strip recharge basin, infinitely long and symmetrically placed in the middle of the aquifer which is bounded on either side by a constant-head drain. The governing equations are simplified so that they are amenable to solution by conventional analytical methods. The major assumption used is that the rise of the free surface above the initial saturated depth is much smaller than the initial saturated depth. The solutions are compared with available experimental data and results from numerical models and are shown to be useful provided the dimensionless recharge parameter is below a certain critical value.
