Saltwater upconing under freshwater producing wells is a classical result of underground water development in coastal regions. Traditional approaches to solving the upconing problem assume a sharp interface between the fresh and saline water. They suffer from a lack of coherence with the physical phenomenon which includes a transition zone between the two fluids and a non-negligible vertical flow below the well.Subjects--Topical Terms:

520 $a Saltwater upconing under freshwater producing wells is a classical result of underground water development in coastal regions. Traditional approaches to solving the upconing problem assume a sharp interface between the fresh and saline water. They suffer from a lack of coherence with the physical phenomenon which includes a transition zone between the two fluids and a non-negligible vertical flow below the well.
520 $a In the present study, efforts have been directed toward a better representation of the physical phenomenon. A transition zone has been represented between the freshwater and the saltwater, and the effect of partial penetration of the well has been considered, allowing the representation of vertical flow above and under the well. The governing equations of continuity, motion, and solute transport are solved simultaneously, subject to specific boundary conditions. The result is the development of three-dimensional partial differential equations describing the drawdown distributions, the growth of the saltwater mound, the development of the transition zone, and the chloride distribution in the pumping region. These equations are formulated into a finite-difference numerical model which is solved using a three-dimensional ADI method.
520 $a The mathematical formulation of the model is well detailed so that it can be adapted to solving the upconing problem under various field conditions. The model accounts for a variety of the aquifer's physical conditions that occur in the field, such as homogeneous or non-homogeneous, isotropic or non-isotropic, and leaky or non-leaky. The model can easily be adapted to simulate water table conditions as well. The model has been verified using existing analytical solutions and field data.
520 $a While the model is specifically designed for simulating the saltwater upconing phenomenon, the approach used can easily be adapted to solving other groundwater transport problems.
