Abstract(s)
A água sendo um recurso natural, fundamental e com extrema importância para a
sobrevivência humana, assim como para a economia mundial, seria necessária a
preservação da mesma com uma gestão eficaz como um recurso hídrico. As águas
subterrâneas são um caso singular desse “lato recurso hídrico” e têm um papel
fundamental para uma vida saudável e sustentável do ser humano. Sendo assim, é a
Hidrogeologia ou a Geohidráulica, que estuda as águas subterrâneas, que permite
caracterizar de forma fiável, as várias etapas e processos associados à circulação das
águas que se infiltram no sub-solo, assim como as reservas aquíferas e sua qualidade.
Assim, a presente dissertação debruça-se sobre o estudo de ocorrências de águas
subterrâneas especiais, como origem em sistemas aquíferos relativamente profundos,
em rochas graníticas, de uma região interior de Portugal que está a ter um
despovoamento e uma tendência de desertificação, e onde é fundamental conhecer este
tipo de recursos, que podem ajudar a fixar populações e criar riqueza.
Sendo assim, no Capítulo 1, Introdução, apresentam-se os objetivos do presente
trabalho, descreve-se a importância das águas subterrâneas especiais, assim como a
organização do trabalho e os seus aspetos metodológicos, nomeadamente sobre a
pesquisa bibliográfica, o trabalho de campo e o trabalho de laboratório/gabinete. No
Capítulo 2, Águas subterrâneas, apresentam-se alguns conceitos fundamentais e
históricos, como a classificação utilizada neste trabalho, o contexto legal deste tipo de
águas assim como outros elementos importantes que servem de base ao desenvolvimento
do caso prático. No Capítulo 3, Caso de estudo: Região de Tabuaço, primeiramente
caracteriza-se a região em estudo, como os vários tipos de enquadramento, desde
geográfico, geomorfológico, geológico e hidrogeológico, tendo-se verificado a existência
de duas principais áreas de interesse à exploração de águas minerais: o Setor da Ponte
do Fumo, e o Setor de São Torcato. Nestes setores desenvolveram-se os aspetos
hidrogeológicos, apresentando-se elementos de reservas aquíferas e de locais potenciais
a futuras captações. Por último, no Capítulo 4, Conclusões, abordam-se os aspetos mais
relevantes em termos conclusivos, sendo de salientar a particularidade da água da Ponte
do Fumo ser já uma realidade como água do tipo Sulfúrea, água que pertence ao mesmo
grupo da água termal de São Pedro do Sul e de outras termas de importância relevante
no interior de Portugal.
As water is a natural resource, fundamental and extremely important for human survival, as well as for the world economy, it would be necessary to preserve it with an effective management as a water resource. Groundwater is a unique case of this “large water resource” and has a fundamental role in the healthy and sustainable life of human beings. Therefore, it is Hydrogeology or Geohydraulics, which studies groundwater, which allows to reliably characterize the various stages and processes associated with the circulation of water that infiltrates into the subsoil, as well as the aquifer reserves and their quality. Accordingly, this dissertation focuses on the study of occurrences of special groundwater, as an origin in relatively deep aquifer systems, in granitic rocks, in an interior region of Portugal that is experiencing depopulation and a tendency towards desertification, and where it is essential to know these types of resources, which can help to settle populations and create wealth. Therefore, in Chapter 1, Introduction, the objectives of this work are presented, the importance of special groundwater is described, as well as the organization of work and its methodological aspects, namely on bibliographic research, field work and laboratory/cabinet work. In Chapter 2, Groundwater, some fundamental and historical concepts are presented, such as the classification used in this work, the legal context of this type of water, as well as other important elements that serve as a basis for the development of the practical case. In Chapter 3, Case Study: Region of Tabuaço, the region under study is first characterized as the various types of framing, from geographic, geomorphological, geological and hydrogeological, having verified the existence of two main areas of interest to the exploration of mineral waters: the Sector of Ponte do Fumo, and the Sector of São Torcato. In these sectors, hydrogeological aspects were developed, presenting elements of aquifer reserves and potential sites for future captures. Finally, in Chapter 4, Conclusions, the most relevant aspects are addressed in conclusive terms, highlighting the particularity that the water from Ponte do Fumo is already a reality as Sulphurous water, that belongs to the same group as thermal water of São Pedro do Sul and other thermal stations of relevant importance in the interior of Portugal.
