Resumo(s)
O Parque Empresarial do Barreiro (PEB) localiza-se no concelho do Barreiro e corres-
ponde ao território da antiga Companhia União Fabril (CUF), onde desde o início do século
XX, foram desenvolvidas várias atividades industriais.
Na década de 40, a área foi objeto de expansão através da conquista de terrenos ao rio
Tejo. Foram utilizados como aterro solos arenosos dragados do rio, resíduos de fosfogesso,
resíduos de pirite, lamas diversas, entre outros, resultantes das atividades industriais existen-
tes no local.
Estes materiais possuem características hidráulicas bastante diversificadas, sendo que os
mesmos poderão conter também diversos tipos de contaminantes industriais orgânicos, inor-
gânicos e radiológicos.
Esta expansão causou modificações nos sistemas hidrogeológicos e no modo como o es-
coamento subsuperfícial das águas se desenvolve.
A presente dissertação tem como objetivo principal melhorar o nível de conhecimento
sobre o funcionamento do escoamento subsuperfícial subterrâneo no local, através da cons-
trução de um modelo numérico dos escoamentos ocorrentes nas unidades mais superficiais,
observadas nas sondagens realizadas no PEB em 2010.
Este modelo não só poderá servir de suporte à modelação do transporte reativo de di-
versos tipos de contaminantes como ser atualizado de acordo com as diversas ações de trata-
mento e remediação que sejam preconizadas na área.
The Barreiro Business Park (PEB) is located in the municipality of Barreiro and corre- sponds to the territory of the former Companhia União Fabril (CUF), where since the begin- ning of the 20th century, various industrial activities have been carried out. In the 1940s, the area was expanded through the conquest of lands belonging to the Tagus River. Sandy soils dredged from the river, phosphogypsum residues, pyrite residues, various muds, among others, that resulted from the industrial activities existing at the site were used as landfill. These materials have very diverse hydraulic characteristics, and they may also contain different types of organic, inorganic, and radiological industrial contaminants, this expansion caused changes in hydrogeological systems and in the way subsurface water flow develops. The main objective of this dissertation is to improve the level of knowledge about the functioning of the underground subsurface flow in the area, through the construction of a numerical model of water flow occurring in the most superficial units, observed in the surveys carried out in the PEB in 2010. This model will not only be able to support the modeling of reactive transport of differ- ent types of contaminants, but also be updated according to different treatment and remedia- tion actions that may be advocated in the area.
