Gestão de reservatórios com sistema de apoio à decisão espacial: o caso do açude Castanhão

Abstract

In Brazil, the Water Law in 9433, of 08/01/1997, based on the National Policy of Water Resources, defines water as a limited natural resource and economic value added, whose management is subject to analysis and operation, according its multiple uses. As an indispensable asset to life, water, in its abundance or scarcity, creates conflict and differing opinions as to its use, because of its limited nature and given to her vocation to foster relations and human actions. Distributed irregularly in time and space, even under conditions of geography, climate and weather, the water thus assumes crucial importance for living beings. Despite being considered a good nature, characteristic of renewable, no overriding need for it to be preserved and managed well, earning a realistic analysis of which is a finite resource and random occurrence. Nowadays, that global climate change pose to the strong showing aggression to the environment, with the requirement of positive responses in their favor, the management of this well, as precious as threatened, it becomes a point of reflection, pointing to the importance of acquiring new knowledge and new forms of governance. The different viewpoints agents and decision makers involved in the process, eventually causing disagreements, given the complexity of the scenarios under consideration, which transcends the mathematical modeling and requires increasingly persistent storage of individual experiences and knowledge or group, in time and space, these knowledge only capable of consolidation, with the use of the tools of rapid digital computing. We understand that both the management, the planning of water resources only become possible to optimize results, if there is an integration of various technologies, collaborative environment that promotes overcoming obstacles and meeting the demand for rational water reserves , joining technique and common sense in the service of the community. The integration of real and imaginary, in the constant struggle for the improvement of human conditions, anticipated future needs of humanity in the face of uncertainties that are announced at the time that it makes possible the conscious orientation to support aspects involved, focusing on freedom of action.
