Book excerpt: Le bassin molassique de Carpentras est constitué de formations miocènes sablo-argileuses présentant de nombreuses variations de faciès. Il renferme un réservoir aquifère complexe aux caractéristiques hydrodynamiques intrinsèques médiocres (perméabilité comprise entre 10 exposant -4 et 10 exposant -7 m.s exposant -1) mais dont la puissance est importante (600 m d'épaisseur). La qualité chimique de l'eau est excellente (naturellement potable) ; l'exploitation est facile et bon marché. Depuis les années 1960, le nombre de forage a augmenté rapidement et sans contrôle. En 2006, on compte des milliers d'ouvrages sur 600 km2. Dans un contexte de rationalisation des usages de l'eau, il est apparu nécessaire de faire un état des connaissances et d'actualiser celles-ci pour construire un schéma de fonctionnement du système aquifère. Ce travail aborde la géologie, l'hydrodynamique et l'hydrochimie du bassin. Chaque élément fait l'objet d'une revue bibliographique critique et est approfondi par l'acquisition et l'analyse de données nouvelles. L'étude géophysique des bordures du bassin par tomographie de résistivité électrique permet de proposer un schéma de l'organisation des corps sédimentaires. Le suivi mensuel du niveau de l'eau dans 51 ouvrages pendant 20 mois révèle l'influence saisonnière très nette des pompages. Enfin deux campagnes de prélévements et d'analyses des ions caractéristiques des eaux du bassin (100 éch.) ont été menées en 2004 et 2005. La comparaison des résultats avec ceux acquis en 1985 et 1996 permet une approche spatio-temporelle des concentrations (évolution de la concentration nitratée, temps de séjour). On aboutit à un modèle hydrogéologique simple mais complet. La modélisation est alors utilisée comme un outil de synthèse des informations et des hypothèses de fonctionnement. Elle permet ainsi une visualisation générale du fonctionnement de l'aquifère et met en évidence les éléments qui nécessiteraient des investigations supplémentaires pour améliorer la compréhension

Available in PDF, EPUB and Kindle. Book excerpt: By 2050, the demand for water to sustain world agriculture will increase by seventy-five per cent in order to feed an estimated nine billion inhabitants. Increased amounts of water will be required for irrigation and for industrial and domestic use. Natural ecosystems will be threatened by the expansion of agricultural land and by a reduction in water availability, while climate change will exacerbate the situation. Management of available resources, particularly groundwater, will become more critical and aquifers will need to be managed for the benefit of all. These selected papers were first presented at the International Association of Hydrogeologists, Dijon 2006, and are divided into six themes: large aquifers, resource assessment; large aquifers, water salinity and evolution; karstic and carbonate aquifer systems; geothermal aquifer systems; aquifer contamination studies and aquifer monitoring systems and management. The volume also includes a short biography of Henry Darcy and illustrates his contribution to science. Five invited contributions describe modern methods for estimating the hydraulic conductivity of aquifers.

This book was released on 2019-03-14 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprises the selected papers from the 1st Springer Conference of the Arabian Journal of Geosciences (CAJG-1), Tunisia 2018. The volume is of interest to all researchers and practitioners in the fields of Hydrology, Hydrogeology, Hydrochemistry, Water Resources and Hydrologic Engineering. Water is a dynamic, finite, and vulnerable but resilient natural resource to be protected in an environmentally sustainable manner. Water systems in different frameworks requires a comprehensive understanding of climatology, geology, hydrogeology, hydrochemistry, hydrodynamics, and surface hydrology. In addition, it is highlighted the role of the variability and climate change in water systems. Furthermore, water has a vital significance to the entire socio-economic sector. This volume offers an overview of the state-of-the-art related to water science and technology in model regions in Europe, Africa, Middle East, Asia and America, but mainly focuses on the Mediterranean environment and surrounding regions. It gives new insights on characterisation, evaluation, quality, management, protection, modelling on environmental hydrology, groundwater, hydrochemistry, sustainable water resources studies and hydrologic engineering approaches by international researchers. Main topics include: 1. Hydrology, Climatology and Water-Related Ecosystems 2. Hydrochemistry and Isotopic Hydrology 3. Groundwater Assessment and Management: mapping, exploration, abstraction and modelling 4. Water Resources Sustainability and Climate Change 5. Hydrologic Engineering and Urban Groundwater
