well 3.
4. Results and Conclusions
A simulation-optimization model for development and management of
groundwater in coastal areas is developed. The proposed model can be
used to evaluate not only the optimal freshwater pumping rates and the
well locations but also the freshwater injection or the saltwater pumping
rates to protect freshwater pumping wells from saltwater intrusion. Integrity
of the groundwater environment is represented by three parameters indi-
cating changes in the freshwater head, the saltwater intrusion area and
the saltwater volume. The use of a numerical sharp interface eliminates, at
the expense of more computer time, most of the limitations of analytical
solutions that are used in previous optimization models.
