Resumo

The Bocaina dam, in the semi-arid region of the State of Piauí, with a capacity of 106 hm³ of water, was built with the objective of regularizing the Guaribas River, among other uses. Over the past three decades, use for irrigation and water supply in neighboring cities has increased significantly. The objective of this study is to analyze, by means of several multicriteria methods, the alternatives of operation of the afore mentioned reservoir in order to meet multiple uses. Five alternatives for reservoir operation, socioeconomic and environmental development were analyzed. For this, four different multicriteria techniques were used: i) weighted average method (WAM); ii) compromise programming (CP); iii) Promethee method with weighted averages (Promethee_WAM) and iv) Promethee method.
