Development of a Combined Quantity and Quality Model for Optimal Management of Unsteady Groundwater Flow Fields

摘要

Alternative techniques are presented for incorporating conservative solute transport equations into computer models designed for optimizing groundwater extraction rates. The equations assume unsteady two-dimensional flow, and dispersed conservative solute transport. Implicit and explicit finite difference equations for solute transport are compared for practicality. After calibration, the equations are used in a MODCON procedure, an integrated series of five optimization or simulation modules. Results of the calculations are compared with those resulting from a model based upon the method of characteristics. The procedure is applicable for an entire aquifer system, or for a subject.
