Hydrogeology of hard-rocks in the Portuguese Iberian Massif : Porto urban area and Serra da Estrela mountain region

An integrated multidisciplinary approach will be adopted in order to carry out a broad characterisation of the groundwater in the Porto urban area and Serra da Estrela mountain region (Iberian Massif, Northern and Central Portugal). Such an approach will contribute to improve groundwater management and protection, under the sustainability framework. Research will include the following main tasks: a) presentation of a geologic, morphotectonic, hydrologic and climatic outline; b) hydrogeologic inventorying and definition of a network of surface and ground water monitoring points; c) fieldwork campaigns, in order to collect water samples for chemical and isotopic analysis

Hydrogeological study of A High Mountain Area (Serra da Estrela, Central Portugal) : a multidisciplinary approach : uma abordagem multidisciplinar

The results of a preliminary hydrogeological study of the river Zêzere catchment upstream of Manteigas (Serra da Estrela Natural Park, Central Portugal) are presented. In this mountain region, different types of groundwater and surface water (used in several economic activities) occur. The methodology adopted in this study emphasizes the way how Geology, Geomorphology, Geophysics, Geochemistry, Soil Science and Hydrogeology contribute to the description of the hydrological phenomena taking place in the catchment, such as infiltration and aquifer recharge and groundwater flow and geochemistry - allowing to develop better hydrogeologic conceptual models. The hydrological modelling in course includes the use of the VISUAL BALAN code, which is being coupled to a GIS. The hydrogeochemical techniques are highlighted as well as its preliminary results concerning major and minor elements. The thermomineral water study includes the identification of the reservoir’s geologic material, the characterization of water-rock interaction and geothermometry
