- Abstract
- Competing interests to water have traditionally been addressed through consultative processes often supported by surface water simulation modelling. Whilst such models are highly effective in demonstrating the effect of changes in system operation, the modelling process is limited to finding one solution at a time for a given set of conditions. Moreover, such traditional approaches have been challenged by the need to develop sustainable water management plans which attempt to meet the need of all users by searching for the optimal operating rules. In recent times there has been growing interest in linking optimisation techniques with simulation models in order to build on the strengths of both modelling approaches in the search for optimal solutions. The modelling approach adopted for this study uses the Elitist Non-dominated Sorting Algorithm (NSGA-II) as the optimisation engine and the REource ALlocation Model (REALM) software as the simulation engine. This optimisationsimulation model is applied to the Wimmera-Mallee Water Supply System which is a complex multireservoir system located in Western Victoria (Australia). The aim of this study is to demonstrate the effectiveness of using an optimisation-simulation modelling approach to develop long-term optimal operating rules. A base case scenario representing the current operating regime is used as a reference point to compare the optimal operating rules produced by the modelling procedure. The results show that by changing certain rules within the current operating regime, the reliability of supply of environmental flows can be improved without affecting consumptive users' reliability of supply, in order to achieve globally optimal operating rules. © 2012 Engineers Australia.; Proceedings of the 34th Hydrology and Water Resources Symposium, HWRS 2012
