- Groundwater Vulnerability Mapping and Ancestral Systems of Water Galleries (Porto Urban Area, NW Portugal): A Design on Nature-Based SolutionsPublication . Freitas, Liliana; Afonso, Maria José; Devy-Vareta, Nicole; Pereira, Alcides J. S. C.; Carvalho, José Martins; Chaminé, Helder I.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 multidisciplinary approach was applied in Porto urban area (NW Portugal), to assess the urban groundwater supply and ancestral network of water galleries and springs. The infiltration potential index in urban areas (IPI-Urban) is dependent on several parameters (e.g. lithology, structure, weathering grade, morphotectonics, land use, drainage, slope, rainfall, anthropogenic and urban hydraulic features, like the water supply, the sewer and the stormwater networks) which can be overlapped and cross-linked in a GIS environment. Moreover, several vulnerability indexes (DRASTIC, GODS, DRASTIC-Fm, SINTACS and SI) were outlined within a combined approach, and an evaluation of urban recharge was performed. All these permitted to improve the hydrogeological conceptual model for Porto urban area. Therefore, those old underground structures could be a positive asset as socio-economic, environmental and heritage drivers if are used nature-based solutions and good geoethical practices.
- Over Fifty Years of Hydrogeological Practice and Geoethics: An Intergenerational View of a Changing WorldPublication . Carvalho, José Martins; Chaminé, Helder I.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 hydrogeology practice must encompass the geoethical approach. Water supply and infrastructure design and construction for groundwater monitoring are not popular nowadays around the scientific and technical community. However, thousands and thousands of wells and boreholes are drilled worldwide annually, without appropriate hydrogeological support. A professional hydrogeologist cannot support, for example, policies of abandon of fieldwork, leaving the aquifer exploitation restrained to high levels of management and governance. Those practices must be developed through proper conceptual site modelling based on field and laboratory data, complemented by GIS mapping, geovisualization techniques, numerical tools to predict scenarios and climate change understanding. On the ethical point of view, this systematic methodology underpins personal scientific integrity but also a comprehensive understanding of the problem to solve. That includes the moral decisions to be made regarding the undertake of the pure and applied hydrogeology in the practice, as well as the professional appropriate use of the scientific advancements in groundwater science, technology, and management.
