Abstract
The interaction of the wetting front, described by the Boussinesq equation, with an impervious wall is considered using a superposition principle. A number of approximate solutions are compared with the numerical solution of the Boussinesq equation. The results show that the superposition approach provides an excellent method for obtaining an approximate solution.
