Download or read book Use of Chlorofluorocarbons in Hydrology written by International Atomic Energy Agency and published by IAEA. This book was released on 2006 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater is used to meet almost half of the global freshwater demand for domestic and agricultural use. Hydrological investigations to assess groundwater resources and to develop sustainable management strategies require a variety of scientific information, including the occurrence and rate of aquifer recharge. This publication explains the chlorofluorocarbon (CFC) technique for dating groundwater, including its scientific basis, sampling and measurement methods, interpretation and limitations of data, and a variety of case studies. It is intended to facilitate a comparative analysis of the CFC and isotope techniques and a wider use of the CFC technique under appropriate conditions.

Download or read book Environmental Tracers in Subsurface Hydrology written by Peter G. Cook and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Tracers in Subsurface Hydrology synthesizes the research of specialists into a comprehensive review of the application of environmental tracers to the study of soil water and groundwater flow. The book includes chapters which cover ionic tracers, noble gases, chlorofluorocarbons, tritium, chlorine-36, oxygen-18, deuterium, and isotopes of carbon, strontium, sulphur and nitrogen. Applications of the tracers include the estimation of vertical and horizontal groundwater velocities, groundwater recharge rates, inter-aquifer leakage and mixing processes, chemical processes and palaeohydrology. Practicing hydrologists, soil physicists and hydrology professors and students will find the book to be a valuable support in their work.

Download or read book Isotope Tracers in Catchment Hydrology written by C. Kendall and published by Elsevier. This book was released on 2012-12-02 with total page 870 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents a new "earth systems" approach to catchments that encompasses the physical and biogeochemical interactions that control the hydrology and biogeochemistry of the system. The text provides a comprehensive treatment of the fundamentals of catchment hydrology, principles of isotope geochemistry, and the isotope variability in the hydrologic cycle -- but the main focus of the book is on case studies in isotope hydrology and isotope geochemistry that explore the applications of isotope techniques for investigating modern environmental problems. Isotope Tracers in Catchment Hydrology is the first synthesis of physical hydrology and isotope geochemistry with catchment focus, and is a valuable reference for professionals and students alike in the fields of hydrology, hydrochemistry, and environmental science. This important interdisciplinary text provides extensive guidelines for the application of isotope techniques for all investigatores facing the challenge of protecting precious water, soil, and ecological resources from the ever-increasing problems associated with population growth and environmental change, including those from urban development and agricultural land uses.

Download or read book Hydrogeology and Groundwater Modeling Second Edition written by Neven Kresic and published by CRC Press. This book was released on 2006-10-26 with total page 836 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coupling the basics of hygrogeology with analytical and numerical modeling methods, Hydrogeology and Groundwater Modeling, Second Edition provides detailed coverage of both theory and practice. Written by a leading hydrogeologist who has consulted for industry and environmental agencies and taught at major universities around the world, this unique book fills a gap in the groundwater hydrogeology literature. With more than 40 real-world examples, the book is a source for clear, easy-to-understand, and step-by-step quantitative groundwater evaluation and contaminant fate and transport analysis, from basic laboratory determination to complex analytical calculations and computer modeling. It provides more than 400 drawings, graphs, and photographs, and a variety of useful tables of all key groundwater parameters, as well as lucid, straightforward answers to common hydrogeological problems. Reflecting nearly ten years of new scholarship since the publication of the bestselling first edition, this second edition is wider in focus with added and updated examples, figures, and problems, yet still provides information in the author's trademark, user-friendly style. No other book offers such carefully selected examples and clear, elegantly explained solutions. The inclusion of step-by-step solutions to real problems builds a knowledge base for understanding and solving groundwater issues.

Download or read book Hydrologic Sciences written by Proceedings of the 1997 Abel Wolman Distinguished Lecture and Symposium on the Hydrologic Sciences and published by National Academies Press. This book was released on 1998-11-25 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrologic science, an important, interdisciplinary science dealing with the occurrence, distribution, and properties of water on Earth, is key to understanding and resolving many contemporary, large-scale environmental issues. The Water Science and Technology Board used the opportunity of its 1997 Abel Wolman Distinguished Lecture to assess the vitality of the hydrologic sciences by the hydrologic community. The format included focus by lecturer Thomas Dunne on the intellectual vitality of the hydrologic sciences, followed by a symposium featuring several invited papers and discussions. Hydrologic Sciences is a compilation of the Wolman Lecture and the papers, preceded by a summarizing overview. The volume stresses a number of needs for furtherance of hydrologic science, including development of a coherent body of transferable theory and an intellectual center for the science, communication across multiple geo- and environmental science disciplines, appropriate measurements and observations, and provision of central guidance for the field.
