The paper discusses three-dimensional problems that include a denser fluid overlain by water in an unconfined aquifer. The two fluid regions are bounded by two-dimensional surfaces, including a nonlinear free surface as well as a nonlinear moving interfacial boundary separating the fluids. Numerical examples include pumping wells located in each fluid layer. The wells are modeled as point sinks in this paper, although a more complete representation is possible. The fluid response due to one or both of the wells operating is considered in order to maximize the withdrawal of one fluid from the porous material.
