“…This study was successfully undertaken through the combination of several major steps, where all the data collection techniques can be classified into two main categories ( Figure 2) [21,22,26,47,48]: (i) mapping data: which include topography, remote sensing, morphotectonics, structural geology, land use and climatology; (ii) field and laboratory data: which comprise rock mass geotechnics, hydrogeological inventory, and hydrogeochemical and isotopic analysis.…”

Hard-rock catchments are considered to be source of valuable water resources for water supply to inhabitants and ecosystems. The present work aims to develop a groundwater vulnerability approach in the Caldas da Cavaca hydromineral system (Aguiar da Beira, Central Portugal) in order to improve the hydrogeological conceptual site model. Different types of information were overlaid, generating several thematic maps to achieve an integrated framework of key sectors in the study site. Thus, a multi-technical approach was used, encompassing field and laboratory techniques, whereby different types of data were collected from fields such as geology, hydrogeology, applied geomorphology and geophysics and hydrogeomechanics, with the fundamental aim of applying the so-called DISCO index method. All of these techniques were successfully performed and an intrinsic groundwater vulnerability to contamination assessment, based on the multicriteria methodology of GOD-S, DRASTIC-Fm, SINTACS, SI and DISCO indexes, was delineated. Geographic Information Systems (GIS) provided the basis on which to organize and integrate the databases and to produce all the thematic maps. This multi-technical approach highlights the importance of groundwater vulnerability to contamination mapping as a tool to support hydrogeological conceptualization, contributing to improving the decision-making process regarding water resources management and sustainability.

“…When trying to manage a resource in the face of uncertainties, it is important to assess the seriousness and type of the assumed problem and must be seen in the overall framework of global sustainable development and towards inclusive ethics of using georesources responsibly [1,17]. Water resources all over the world are subjected to increasing pressure in terms of both quantity and quality [1]. Dal Lake catchment has been under tremendous anthropogenic pressure since more than three decades.…”

The current study was carried out to monitor the changing land use/cover and assess the impact of solid waste on water quality of Dal Lake in Srinagar city (India). Various data sets were used for analysis of geomorphology studies such as socioeconomic changes and water quality status. The study reveals that agriculture land decreased from 13 to 11.39%, forests from 2.55 to 1.41%, water from 22.05 to 19.85%, and plantation from 22.28 to 14.65%. Although the study also reveals there has been an increase in built-up from 8.87 to 23.90%, aquatic vegetation increased from 10.25 to 17.03%. Finally, changes in all categories were correlated and it was found that the wards surrounding the Dal Lake show the dynamic change in land use/cover and solid waste parameters which in turn changed the water quality of Dal Lake. It was observed that solid waste generated varies from ward to ward depending upon land use cover and socio-economics. In order to protect the lake basin, controlled human activities, land use and water resources within the catchments are to be done in cooperation between the government departments, local authorities and the general local community around Dal Lake catchment.

“…As flutuações dos níveis de água (NA) subterrâneos são o resultado de processos como mudanças do volume de água armazenada no aquífero (recarga por infiltração de chuva e rios, influência de poços vizinhos, áreas de irrigação), mudanças na pressão atmosférica e mudanças causadas por deformação do aquífero (efeitos de maré ou terremotos). Alguns autores consideram que a explotação de aquíferos deve ser norteada pela sustentabilidade ambiental do sistema hídrico no sentido de equilibrar as condições de bombeio à mitigação de suas consequências (MAI-MONE, 2004;ZHOU, 2009;CHAMINÉ, 2015).…”

A mensuração dos componentes do balanço hídrico de uma bacia do ponto de vista temporal e espacial é extremamente relevante na gestão dos recursos hídricos e no entendimento das flutuações de níveis da água subterrânea. O aquífero Urucuia vem sendo monitorado por dataloggers instalados em poços dedicados que mostram um declínio contínuo nos níveis d’água atingindo até 1,1m/ano. Foi realizada a análise isotópica em conjunto com a simulação numérica de fluxo em estado estacionário e transiente na porção meridional do aquífero Urucuia-Bahia (23% da área aflorante total) para descrever a dinâmica dos componentes do balanço hídrico entre 2005 e 2018. A análise isotópica evidencia a interação rio-aquífero e o efeito da evapotranspiração na recarga. Os resultados mostram diminuição progressiva da recarga entre 2012 e 2017, sendo fortemente influenciada pela evapotranspiração e diminuição das chuvas, causando o declínio nos níveis d’água subterrâneos e do fluxo de base dos rios, também influenciado pelo bombeamento dos poços. Adicionalmente o modelo numérico foi desenvolvido para gerar respostas degrau a uma diminuição de recarga em 10% mostrando que cargas hidráulicas e fluxos de base tardam aproximadamente uma década para se reequilibrarem. Os resultados evidenciam a importância de monitoramento hidroclimatológico contínuo e mensuração das retiradas, visando acompanhar a dinâmica entre demandas e disponibilidades hídricas.
