Abstract

Drought management should be constructed from three pillars: the monitoring and early warning, risk assessment and impacts and the development of actions and/or programs of preparation, mitigation and response to drought. This work deals with the definition of the dry States and which indexes and indicators that should be used to monitor the occurrence of these dried States. The monitoring system is key to trigger the measures associated with each State of drought. The indicators serve as a watch pointers that indicate which stage of drought. It is observed, however, that in this special clock time can go back, that is, the drought may lose severity before reach more severe levels. In this work the analysis of indicators to identify the States of drought in various temporal scales in order to discover more appropriate indicators for drought, which impacts the accumulation of water in reservoirs. This analysis includes an assessment of the difference on the classification of the severity of the hydrological drought, in order to provide future actions in accordance with each State of drought. In the second time sought through this job perform the construction and deployment of the reservoir operation policy and from this study to analyse and propose levels with goals of operation to the Jucazinho system, a major dam that serves approximately a total of 15 cities located in the wild of Pernambuco State Northeast region of Brazil. To reach these goals we used a specific software that enables the programming of a simulation and optimization algorithm. With the data obtained from the simulations enables the presentation of various scenarios, with comparison of the results obtained with the values used targets currently in operation of the Jucazinho system and thus enable the decision-making of managers of the water supply system in order to minimize the risks and vulnerabilities hydropower generated by historic droughts in the region of study. 1.
