Abstract
In the southern regions of Mediterranean Europe, the greatest part of water resources for supply systems are derived from artificial reservoirs. A simplified approach to the need of inserting water quality aspects in the mathematical optimization model can be achieved considering the trophic state of reservoirs. In recen91t years, Trophic State Index (TSI) based on Carlson’s (1977) classification appears to have obtained general acceptance as a reasonable manner of classifying stored water in reservoirs; it enables to insert quality constraint in the water management optimization model also considering large size multi-reservoir and multi-user systems. Using TSI index and concentration density values of the most toxic algae, water quality aspects can be easily considered in an optimization model specifically designed for large system management optimization. The usefulness of a mixed quantity-quality optimization approach has been confirmed by WARGI application to a real multi-reservoir water resources system in southern Sardinia
