The chapter illustrates a Decision Support System (DSS) for multi-reservoir water resource systems, named WARGI (Water Resources system optimization aided by Graphical Interface). WARGI was upgraded in the SEDEMED II Project to implement a mixed approach that uses optimization and simulation techniques which identifies short and medium-term actions to be implemented in system management according to a proactive approach. Under drought conditions, the DSS aims to predict in advance the consequences of management assumptions in a predefined system configuration. The optimization module considers future hydrological and demand scenarios to modify the set of decision variables to be adopted by the simulation module. Lastly, WARGI’s application to the water resource system of Southern Sardinia (Italy) is illustrated
