Operação de um sistema de reservatórios para usos de conservação.

Abstract

A simulation model of the reservoir operation is applied to a system composed of two series reservoirs, Ingeniero flvidos and São Gonçalo, located in the semi-arid region of the State of Paraíba, in the Northeast of Brazil. The HEC-3, based on the operational policy of multiple zoning reservoir levels, determines the monthly releases that must be made in order for the demands to be addressed rationally. Emphasis is given to the uses of supply and irrigation, characteristic demands of the system. The study analyzes the situation for the current demands and for the demands of the future, for both cases the series of historical flows and the series created artificially from the generated data are used; which makes it possible to simulate the system against the existence of periods ranging from one year to five consecutive years of drought. The results indicate the system with water scarcity already for the current situation show the importance of operating the system with restrictions linked to the volume stored in the reservoirs and demonstrate the possibility of using a simulation model of reservoirs operation in the management of surface water resources of a region.
