The issue of managing the water needs during periods of deficits can be studied in terms of optimization
between the various users (Georgiou et al., 2006), or though the simulation of hypothetical scenarios (Strzepek et
al., 1989). In this model, the logic of optimization has been made more flexible in terms of operational
management, to obtain an instrument that can be adapted to the political and economic issues related to the various
uses and in the territorial features.
