1. Analysis of solar photovoltaic energy potential in Brazilian hydroelectric reservoirs through floating panels
Abstract Sustainability, a concept used to exploit natural resources without harming future generations, is being applied to power generation. In Brazil, the main source of electric energy comes from hydroelectric plants, due to abundant water resources. However, the implementation of these plants causes irreversible impacts on the environment and society.

2. Modelo de PrevisÃo de VazÃo Aplicado ao Nordeste Brasileiro Utilizando a InformaÃÃo ClimÃtica para Auxiliar a OperaÃÃo de Hidrossistemas. / Streamflow Prediction Model Applied to Northeastern Brazil Using Climate Information to Support Hydrosystems Operation
Sabe-se que a Ãgua à um recurso essencial à sobrevivÃncia da humanidade. Gestores ambientais do mundo inteiro vÃm chamando atenÃÃo para o problema da sua escassez e mà gestÃo. O presente trabalho destacou que no Nordeste Brasileiro, particularmente no semiÃrido, a escassez hÃdrica acentua-se por conta das caracterÃsticas peculiares que o diferem

3. Impacto da RecuperaÃÃo dos Investimentos na Infraestrutura HÃdrica (Barragens e Adutoras) sobre a CobranÃa pelo Uso da Ãgua. / Impact of the recovery of investment in water infrastructure (dams and water pipelines) on charging for water use.
The works of water infrastructure often clash over the issue of lack of financial resources for the construction and operation. It then becomes the hypothesis of obtaining the funds for water infrastructure construction by charging for the raw water. Then, comes up the question: what is the impact on water charges if the cost of water infrastructure construc

5. Ferramenta para Avaliação da Energia Firme Baseada em Técnica de Pontos Interiores / A tool for Evaluation of Firm Energy Based on Interior Point Technique
The energy sector planning is fundamental to assure the energy supply at the smallest costs and risks and with the smallest socioeconomic and environmental impacts for the society. These factors as well as the aspects complexity involved in the industry operation of the electrical energy production explain the importance of the energy sector planning. Nowada

6. Simulating the use of the agricultural sector water in the Jundiá creek basin / Simulação do uso da água do setor agrícola na bacia do Córrego Jundiá
In the past, the occurrence of the territorial occupation in Brazil was extremely disordered and the inadequate use of the natural resources caused serious negative impacts on the water resources, such as the deterioration of the water and the consequent reduction in the water availability. Nowadays, there are few tools that allow the users and management ag

7. DEVELOPMENT OF A METHODOLOGY FOR THE COORDINATION HYDROTHERMAL-TERM IN ELECTRIC MARKET COMPETITIVE / Desenvolvimento de uma metodologia para a coordenação hidrotérmica de longo prazo em mercado elétrico competitivo
In this work a methodology based on linear programming for long-term hydrothermal scheduling of electric power systems is proposed. The objective of the hydrothermal scheduling is to find an optimal operation for a specific time interval and with high reliability and minimum cost. That is equivalent to determine an optimal generation scheduling for the power

8. Derivation of hedging operation rules of reservoir systems using genetic algorithms / Derivação de regras operacionais de proteção contra déficits de suprimento de sistemas de reservatórios via algoritmos genéticos
The operation rules constitute one of the main elements in the planning and management of water resources systems. The application of the standard operational rules can be present unsatisfactory in periods of drought or imminent drought. These rules can result in periods with deficits of great magnitude, leading the system to a highly vulnerable situation. M

9. Hydrothermal scheduling with storage guide-curves / Planejamento da operação energetica via curvas-guias de armazenamento
The Brazilian electric sector has been passing through successive reforms in the search for an institutional model that allows the optimization of the use of the energetic resources, concealed with the goal of achieving a sustaining development. The energetic planning plays a fundamental roll in this context, thus studies and researches designated to support

10. AnÃlise dos efeitos dinÃmicos em reservatÃrios de grande extensÃo : estudo de caso : ReservatÃrio de Sobradinho
The work deals with dynamic effects analysis in big reservoirs, having as case study the Sobradinho reservoir. From the generation of numerical model of the land using database of the SRTM-90 (Shuttle Radar Topographic Mission, in cooperation of NASA, NIMA, DLR and ASI), tools created by Danish Hydraulic Institute (DHI) for hydrodynamic simulations had been

12. Otimização da operação de sistemas de distribuição de agua abastecidos por bombeamento e reservatorios de regularização
In the present work it was developed an optimization model to water distribution systems operation, supplied by multiple pump stations and multiple reservoirs regulation. The difficulties to reach an appropriate modelling and the excessive simplification of the models have been delaying the appearance of practical solutions more adapted to dimensioning and o
