Abstract
A great deal of optimization models have been developed to support aquifer
planning and management with the goal of arriving at the best decisions in
relation to the number and siting of infrastructures to be built and how to operate
them. A mixed-integer multi-objective linear model has been taken from the
literature to define the best decision for the development of the aquifer of
Querença-Silves (Portugal). It identifies efficient solutions for the location and
design of pumping stations and their catchment area to supply a given number of
demand centers, without disregarding the effect of groundwater management on
the piezometric surface of aquifers and the many facets of groundwater
management. The multi-objective model includes two objectives: (1) the
minimization of aggregate water elevation height, and (2) the minimization of
aggregate water transport length, weighted by the flows conveyed from the
facilities to the centers. The effect of groundwater extraction on the piezometric
surface of the aquifer is modelled with a response matrix method, with the
establishment of maximum drawdown to prevent over-exploitation.
Keywords: aquifer systems, multiobjective models, mixed-integer models.
