Assuring the sustained availability of groundwater from all parts of an aquifer system is analagous to assuring that the potentiometric surface does not change over the long term. Such a steady-state surface is maintained by a specific spatially distributed pattern of groundwater withdrawal. The finite difference form of the linearized Boussinesq equation for steady two-dimensional flow through porous media is used in models that design optimal regional potentiometric surfaces and the conjunctive water use/sustained yield strategies that maintain them. Presented objectives of such models include minimization of unmet water needs, minimization of the regional cost of attempting to satisfy water needs and bi-objective optimization.
