O trabalho final de mestrado consiste no projeto de um sistema hidráulico para reforço de alimentação da albufeira de Fagilde, localizada no rio Dão, distrito de Viseu, a partir da albufeira da barragem de Vilar, em Moimenta da Beira. A albufeira de Fagilde é a origem de água do abastecimento público às populações dos concelhos de Viseu, Mangualde, Nelas e Penalva do Castelo.
A situação dramática do período de seca que ocorreu no fim da estação de verão do ano de 2017, demonstrou a existência de um problema de falta de água para abastecimento público daquela região que é urgente solucionar. A grave carência implicou tomar medidas de recurso para ultrapassar o problema, tendo-se recorrido a camiões-cisterna para transportar água tratada e bruta de outras regiões próximas. As chuvas do inverno de 2018 compensaram a seca de 2017, mas o ano de 2019 surgiu como novo ano de seca, voltando a reacender a discussão sobre o mesmo problema da escassez de água na região.
Fazem parte deste projeto a avaliação do caudal de dimensionamento do sistema (com base na análise dos registos das necessidades do sistema de abastecimento das populações servidas e do regime de caudais afluentes à albufeira de Fagilde), o estudo de 3 soluções técnicas alternativas para o sistema de reforço à albufeira de Fagilde e a conceção e dimensionamento do sistema hidráulico para o reforço de alimentação pretendido.
This final master's work will consist of the design of a hydraulic system to reinforce the supply to the Fagilde reservoir, located on the Dão river, Viseu district, from the Vilar dam reservoir in Moimenta da Beira. The Fagilde reservoir is the source of public water supply to inhabitants spread over the municipalities of Viseu, Mangualde, Nelas and Penalva do Castelo. The dramatic drought situation occurred at the end of the summer season 2017 demonstrated the existence of a serious water availability problem for public supply in that region that need urgently be solved. The serious shortage implied taking remedial measures to overcome the problem, with tank trucks being used to transport raw and treated water from other nearby regions. The 2018 winter rains redressed the 2017 drought, but 2019 emerged as a new year of drought, rekindling the discussion about the same problem of water scarcity in the region. The main objectives of the project were the assessment of the design flow (based on the analysis of water need records for the served populations and on the flow regime affluent to the Fagilde reservoir) and the conception and design of the reinforcement hydraulic system. In this planning phase of the Final Master's Work, three alternative technical solutions for the Fagilde reservoir reinforcement system were considered. These solutions were the target of a comparative technical-economic study.
