Book Synopsis Hydrogéologie d'un aquifère karstique dans les calcaires carbonifères (Néblon-Anthisnes, Belgique) by : Philippe Meus
Download or read book Hydrogéologie d'un aquifère karstique dans les calcaires carbonifères (Néblon-Anthisnes, Belgique) written by Philippe Meus and published by . This book was released on 1993 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse est avant tout consacrée à l'étude des circulations karstiques dans les calcaires carbonifères du Sud de la Belgique. Son objectif est double : d'une part, approfondir la connaissance de l'aquifère à partir de l'étude d'une région limitée située dans le Condroz à l'extrémité Est du synclinorium de Dinant (bassins d'Anthisnes et du Néblon), d'autre part mettre au point des méthodes de mise en oeuvre et d'interprétation des traçages permettant de caractériser le comportement de l'aquifère lié à sa "double perméabilité". Dans ce but, plusieurs aquifères fissurés et karstiques sont comparés. L'introduction générale présente une synthèse des conceptions actuellement utilisées en hydrogéologie karstique et définit le calcaire carbonifère en tant qu'aquifères carbonatés du Sud de la Belgique. La première partie est consacrée à l'étude de la structure et du fonctionnement de deux systèmes karstiques drainant la même nappe dans les calcaires du Tournaisien et du Viséen : le bassin d'Anthisnes, dont l'exutoire est la résurgence de Comblain-au-Pont, et le bassin du Néblon drainé par les sources du Néblon. Les structures de ces deux systèmes sont comparées à l'aide de diverses méthodes géophysiques et à partir d'observation en surface. Les différences de comportement sont liées au développement de la karstification. Elles apparaissent de manière très nette en considérant les réponses naturelles (hydrodynamique, hydrogéochimie) et provoquées (traçages). Dans la seconde partie, une série de tests en écoulement naturel et en écoulement radial convergent permettent d'étudier les propriétés de transport des traceurs au sein de différents aquifères fissurés et karstiques et de dégager des tendances liées à la structure du milieu. Trois types d'aquifère sont envisagés : les calcaires dévoniens et carbonifères, les craies du Crétacé et les tuffeaux du Landénien. Un examen critique des lois d'écoulement et de transport utilisées, ainsi que des différents types de traçages et types de traceur, est effectué au préalable. Plusieurs solutions analytiques sont envisagées pour déterminer les paramètres hydrodispersifs des aquifères. Les dispersivités longitudinales des calcaires sont comprises entre 10 et 100 m, celles des craies entre 2 et 14 m et celles des tuffeaux entre 2 et 5 m.

Book Synopsis Computational Methods in Water Resources X by : Alexander Peters
Download or read book Computational Methods in Water Resources X written by Alexander Peters and published by Springer. This book was released on 1994 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume work constitutes the edited proceedings of the Tenth International Conference on Computational Methods in Water Resources (formerly Finite Elements in Water Resources), held at Heidelberg University, Germany in July 1994, organized jointly by Interdisziplinäres Zentrum für Wissenschaftliches Rechnen (Interdisciplinary Center for Scientific Computing) and Sonderforschungsbereich 359 of Heidelberg University and the Institute of Supercomputing and Applied Mathematics of IBM Heidelberg. The 1994 proceedings present the work of authors from 23 countries. Numerical methods, mathematical modeling and applications to subsurface and surface hydrology are covered by a wide variety of papers. Issues of formation description and modeling, including parameter estimation, heterogeneity, and scaling up continue to attract the attention of a large number of researchers. Several papers edited in this book concern the solution of the Navier--Stokes equations. For applied mathematicians, engineers and geoscientists working in the fields of numerical methods, hydrology, ecology, water resources planning and management, remediation design, porous media research, petroleum engineering and coastal engineering.

Book Synopsis The Norman Frontier in the Twelfth and Early Thirteenth Centuries by : Daniel Power
Download or read book The Norman Frontier in the Twelfth and Early Thirteenth Centuries written by Daniel Power and published by Cambridge University Press. This book was released on 2004-12-16 with total page 660 pages. Available in PDF, EPUB and Kindle. Book excerpt: The twelfth-century borderlands of the duchy of Normandy formed the cockpit for dynastic rivalries between the kings of England and France. This 2004 book examines how the political divisions between Normandy and its neighbours shaped the communities of the Norman frontier. It traces the region's history from the conquest of Normandy in 1106 by Henry I of England, to the duchy's annexation in 1204 by the king of France, Philip Augustus, and its incorporation into the Capetian kingdom. It explores the impact of the frontier upon princely and ecclesiastical power structures, customary laws, and noble strategies such as marriage, patronage and suretyship. Particular attention is paid to the lesser aristocracy as well as the better known magnates, and an extended appendix reconstructs the genealogies of thirty-three prominent frontier lineages. The book sheds light upon the twelfth-century French aristocracy, and makes a significant contribution to our understanding of medieval political frontiers.

Book Synopsis Quantitative Hydrogeology by : Ghislain de Marsily
Download or read book Quantitative Hydrogeology written by Ghislain de Marsily and published by . This book was released on 1986 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to combine two separate themes: a description of one of the links in the chain of the water cycle inside the earth's crust i.e., the subsurface flow; and the quantification of the various types of this flow, obtained by applying the principles of fluid mechanics in porous media. The first part is the more descriptive, and geological of the two. It deals with the concept of water resources, which then leads us on to other links in the cycle: rainfall, infiltration, evaporation: runoff, and surface water resources. The second part is necessary to quantify groundwater resources. It points the way to other applications, such as solutions to civil engineering problems including drainage and compaction; and transport problems in porous media, including aquifer pollution by miscible fluids, multiphase flow of immiscible fluids, and heat transfer in porous media, i.e., geothermal problems. However, the qualitative and the quantitative aspects are not treated separately but combined and blended together, just as geology and hydrology are woven together in hydrogeology.

Book Synopsis Hydrodynamics and Transport for Water Quality Modeling by : James L. Martin
Download or read book Hydrodynamics and Transport for Water Quality Modeling written by James L. Martin and published by CRC Press. This book was released on 2018-05-04 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrodynamics and Transport for Water Quality Modeling presents a complete overview of current methods used to describe or predict transport in aquatic systems, with special emphasis on water quality modeling. The book features detailed descriptions of each method, supported by sample applications and case studies drawn from the authors' years of experience in the field. Each chapter examines a variety of modeling approaches, from simple to complex. This unique text/reference offers a wealth of information previously unavailable from a single source. The book begins with an overview of basic principles, and an introduction to the measurement and analysis of flow. The following section focuses on rivers and streams, including model complexity and data requirements, methods for estimating mixing, hydrologic routing methods, and unsteady flow modeling. The third section considers lakes and reservoirs, and discusses stratification and temperature modeling, mixing methods, reservoir routing and water balances, and dynamic modeling using one-, two-, and three-dimensional models. The book concludes with a section on estuaries, containing topics such as origins and classification, tides, mixing methods, tidally averaged estuary models, and dynamic modeling. Over 250 figures support the text. This is a valuable guide for students and practicing modelers who do not have extensive backgrounds in fluid dynamics.
