This paper introduces Integrated Economic-Hydrologic water modeling at the basin scale, that can provide essential information for policymakers in resource allocation decisions, applied to the Pirapama river basin, in Pernambuco state. Includes hydrologic, institutional, agronomic and economic relationships in a unique framework in order to identify the best allocation of the water resources among their multiple uses before Pirapama reservoir. Furthermore, the best allocation of the alcohol production process’s effluents is also identified. The model has a significant non-linearity level and includes more than 10 thousands variables and equations, so can be considered a complex non-linear system. The piece-by-piece method (Cai et alii 2001) is implemented using the General Algebraic Modeling System (GAMS) to solve this system. GAMS is a high level software to solve mathematical programming problems. The results show the effectiveness of the model for water policy analysis and like a decision support system of the hydrologic questions.
