Abstract:
It is common to find descriptions of optimization models to analyze water resources
systems at corresponding literature, but most of them present model approximations that limit
their use, when analyzing complex systems of reservoirs. Therefore, this work is concerned
with the development of an optimization model to couple with an integrated analysis of
reservoirs and irrigated perimeters, among other water uses, system targeting the
establishment of multi-objective optimal operational policies for water allocation to multiple
users. The nonlinear behavior of hydraulic components were implemented and solved via an
iterative process, through the use of sequential linear programming.
This model was applied at the study of two reservoirs system, Catolé II and Poço
Redondo, which are connected in series at the Piancó river basin. The system’s behavior was
analyzed for five established objectives (to meet water requirements of human supply,
ecological river flow, reservoir target storage volume, net profit and labor required for
agricultural activities) and three hydro-climatic scenarios (dry, normal and rainy) for a time
span of 1 and 5 years. The results have shown that the model is efficient at the selection of
multi-objective optimal operation policies for water allocation, according to established
objectives and constraints.
