In confined aquifers, in which its thickness and hydraulic conductivity is constant, and that there is no storing, with an essentially horizontal flux, the water flow is described by the Laplace equation.

In the saltwater intrusion problem presented here it is necessary to determine the separation line between freshwater and the saltwater. We will consider that both fluids are not miscible, and that the freshwater inflow is done with a constant flux, supposing that the level of the saltwater does not change with time.

In the simplified situation, we will not consider a zone of mixture of both saltwater and freshwater, and trough an iterative process supported in both the kinematic and static conditions that prevail in the interface, it is possible to determine its movement to an equilibrium configuration.
