RESUMO
The study of the water quality in natural or artificial reservoirs is constituted of utmost importance to hinder cultural eutrophication and develop projects for multiple uses. According to Kent et al. (2000) the understanding of cultural eutrophication is an important problem in developing interfaces between civilization and environment. Through the knowledge of reservoir functioning flow diagram and the hierarchy of the factors that act on this it can be proposed management systems with the objective of maintain the quality of water. The energy is the more relevant limit factor for an ecosystem, and the flow energy concept provides not only ways to compare diverse ecosystems, but also enables a relative evaluation of each component of the system. Thus in this present study utilizing the energy fluxes language developed by Odum (1983) it proposes to represent a reservoir as a system. This system provides a general view of reservoir structure and its functions beyond organizing dates and concepts for the eutrophication understanding. Two models had been evaluated and simulated in the time to consider questions related to the process. This process consists to keep inflow of phosphorus in the system in the long term and thereservoir daily metabolic. The models were tested on the basis of the data observed in the Lobo Reservoir. It is verified from the work, that the use of energy flows language, as a tool of the ecology of systems, makes possible the construction of models to represent structures and important functions of the water reservoir system. In this manner the understanding of the real system is facilitated. The systems models are excellent instruments of integration of information and society and can serve to test hypotheses that are difficult to carry out in the field, transforming numerical results into significant messages to theoretical research and for regional planning.
