Insights from a comparative GIS-MCDA groundwater vulnerability assessment in a ...

This work proposes a comprehensive methodology for evaluating fssured hard-rock groundwater resources through an integrative approach based on feldwork techniques, Geographic Information System (GIS)-based mapping, geospatial analysis and multiple-criteria decision analysis (MCDA). The study sites comprise distinct geological settings and geographic contexts, i.e. granitic rocks (NW Portugal) and metasedimentar...

Geothermal energy use, country update for Portugal

The presence of high-temperature geothermal resources, and the production of electricity from geothermal resources in Portugal, are restricted to the volcanic islands of the Azores Archipelago located in the North Atlantic Ocean. Three geothermal binary power plants are installed and running normally in the islands of S. Miguel and Terceira, the most economically developed, with a total capacity running of 26 M...

Over Fifty Years of Hydrogeological Practice and Geoethics: An Intergenerationa...

The exercise of professional hydrogeology is a privilege that requires sound scientific and technical knowledge, field training and interpersonal skills. A skilled hydrogeologist is required to have ethics, deontology, integrity, eco-responsibility, leadership, and behaviour but also the acceptance of the high-standards and codes of ethics and boundaries to avoid discrimination and harassment. In addition, the ...

Groundwater Vulnerability Mapping and Ancestral Systems of Water Galleries (Por...

Groundwater resources are crucial to the settlement of populations, and their quantity and quality are essential to the development of urban areas. In fact, nature-based solutions for water were considered in many places using ancestral systems of water galleries and springs to supply urban areas. That design based in natural solutions had proven during centuries to be much less demanding and resourceful. A mul...

Site appraisal in fractured rock media: coupling engineering geological mapping...

Geotechnical surveys are based on collecting data from fieldwork and are a key element of rock-mass quality assessment in rock engineering. The lessons learned in several engineering projects underline the value of the accuracy of the basic geological and geotechnical data information related to the rock masses description and evaluation. An evaluation based on engineering geosciences, hydraulic and geotechnica...

Groundwater Favourable Infiltration Zones on Granitic Areas (Central Portugal)

The Infiltration Potential Index (IPI) was used at Castelo Novo (Fundão, Central Portugal) to delineate favourable infiltration zones. The Infiltration Potential Index is a valuable tool to include in integrated water resources management in crystalline fractured rocks. An integrated approach combining hydrogeomorphology and GIS was developed applying multiple layers of information (tectonic lineaments, hydroge...

Forecasting and Mass Transport Modelling of Nitrates in the Esposende–Vila Do C...

Esposende–Vila do Conde, a nitrate-vulnerable zone, in the littoral north of Portugal, is contaminated by nitrates of an agricultural origin. Measures have been implemented to reduce that contamination. The effectiveness of the measures was evaluated, predicting the time required for the groundwater body reach the quality standard, i.e., less than 50 mg/L for dissolved nitrates. Two methodologies were used, gro...

From engineering geosciences mapping towards sustainable urban planning

Maps are of key topical importance in urban geoscience and engineering practice, mainly in field data synthesis and communication related to a number of fields, such as geomatic techniques, applied geology and geomorphology, engineering geology, soil and rock geotechnics, slope geotechnics, subsurface site geotechnical investigations, urban hydrology, hydraulics and sanitation, coastal zones management, urban g...
