Análise da operação de reservatórios na bacia do Acaraú: estudo de caso nos açudes Ayres de Sousa e Taquara

Abstract

Among the many aspects presented by the Northeast Region, what stands out most is drought, caused by the scarcity of rainfall, providing poverty and hunger. In this way, the methodology for the simulation of drainage of the Ayres de Sousa and Taquara reservoirs was utilized using the set of sheets of the supplement SAGREH version 10.021 - System of Support to the Management of the Water resources. Regarding the deliberate flow into the Taquara dam, water savings were observed almost throughout the period defined in the allocation. In the month of January a significant contribution of the water supply was verified. In the case of the Ayres de Sousa dam, we observe an inverse situation to the Taquara dam. For the same period, the reservoir was inefficient in terms of saving water in the System. In this way, it is concluded that, as far as the quantitative analysis of the Taquara dam is concerned, it was verified that the flow approved for the dam is compatible with the uses demanded for the system, obtaining reserve values higher than expected. When compared to Ayres de Sousa, where there was an inverse behavior. That is, the installed demand for the dam does not match the observed reality. It is necessary to re-evaluate the data obtained in the first moment, followed by new emptying simulations until obtaining the ideal adjustment for the dam.
