Análise da segurança hídrica do Açude São José II no Sertão Pernambucano.

Abstract

Water is indispensable to human activities and, consequently, to the economic and social development of a society However, water is a scarce commodity and must be well managed to avoid situations of collapse. The Brazilian Northeast faces drought cycles in wich population suffers from the adversities arising with water scarcity. The optimization of reservoir operation coupled with efficient management of water resources contributes to the rational use of water, increasing the water supply capacity during periods of drought. In view of the described, the research aims to use a reservoir simulation technique, through the Hidro worksheet, to study the future water availability, in certain contexts of analysis, of the production of São José II, in São José do Egito, in the interior of Pernambuco. Three scenarios of simulation were elaborated and the capacity of supply for the future population, in a horizon of up to 10 years, of the municipality was projected. The results led to the conclusion that the dam is able to continue supplying the city and should have its operation optimized.
