Abstract in Portuguese
O presente trabalho apresenta soluções e análises desenvolvidas em estruturas extravasoras em aproveitamentos a fio dágua, envolvendo análises nos critérios de operação de diversos tipos de descarregadores, tais como: soleira normal, labirinto, tulipa e comportas específicas. Para tanto se faz necessário o estudo e comparação de resultados a serem desenvolvidos em cada projeto com relação aos fatores hidráulicos, hidrológicos, geológicos, topográficos e dos riscos envolvendo prejuízos decorrentes de falhas nas estruturas hidráulicas. A avaliação de extravasores labirinto em aproveitamentos hidrelétricos de projetos aprovados pela Agência Nacional de Energia Elétrica ANEEL tem o objetivo de analisar a segurança em relação à construção e à operação, com foco no desenvolvimento de descarregadores adequados para cada estudo de caso presentes neste trabalho. Esta avaliação indica as condições geométricas, econômicas e hidráulicas do extravasor labirinto adequado para cada situação de aproveitamento hidrelétrico a fio dágua.

Abstract in English
This paper studies solutions and analysis developed in spillways structures in hydroelectric development trickle, involving analysis of the operation criteria of several types of dischargers, such as threshold normal maze, morning glory and specific gates. For this purpose it is necessary to study and compare the results to be developed in each project about the factors hydraulic, hydrologic, geologic, topographic and risks involving losses due to failures in hydraulic structures. The evaluation of spillways maze in hydroelectric of projects approved by the National Agency of Electric Energy - ANEEL aims to analyze the safety for the construction and operation, focusing on the development of suitable dischargers for each case study in this work. This assessment indicates the geometric, economic and hydraulic conditions of the most suitable spillways maze for each situation of hydroelectric development trickle.
