Download or read book Groundwater and the Environment written by Igor S. Zektser and published by CRC Press. This book was released on 2000-06-21 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, water has been treated as an inexhaustible resource. However, with the growth of population and development of industry and agriculture, freshwater demand has increased drastically, and its shortage felt in roughly 60% of the Earth. As early as 1931, renowned Russian scholar A.P. Karpansky wrote: "Water is not only a mineral resource, not only a means for developing agriculture. Water is a real culture bearer, it is a living blood, that creates life where there was none". Groundwater and the Environment: Remediation Applications and the Global Community covers one of the most important ecological problems - the impact on the environment of intensive groundwater pumping out. Drawing on more than a quarter century of study, Zektser analyses and makes conclusions about groundwater exploitation throughout the world. He focuses on the close connection of groundwater to the environment - its affect on surface water streams, reservoirs, seas, landscapes, and vegetation. The author demonstrates the importance of groundwater to the potable water supply, and its interaction with the environment. He stresses the significance of groundwater as a mineral resource. He provides techniques for assessing and mapping natural groundwater resources and develops these principles for studying water and hydrochemicals in coastal zones. In the last twenty years, the global awareness of groundwater as one of the most important natural resources has grown. Any changes in the groundwater causes changes in the environment. Groundwater and the Environment: Remediation Applications and the Global Community increases your ability to predict the possible changes to the environment and to follow the principle: "When using - protect, when protecting - use!"

Download or read book The Many Facets of Israel s Hydrogeology written by Uri Kafri and published by Springer Nature. This book was released on 2020-11-09 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a collection of essays that address various facets of the hydrogeology of Israel. Despite its small geographic size, Israel exhibits a variety of climates and is located between two regional fluctuating base levels. The respective chapters discuss the variety of hydrogeological configurations and hydrological processes produced by these geographical circumstances. In some cases, the interpretation of these aspects is deliberately left open to debate, because the authors were asked to provide, in addition to their own views, also alternative and even conflicting ones. Hydrogeological configurations similar to those in Israel can be found in other countries around the world. Therefore, researchers, scholars and professionals in this interdisciplinary field can benefit from and directly apply the considerable experience and expertise that has been gathered in Israel over the past few decades.

Download or read book Groundwater Surface Water Interactions written by Habil. Jörg Lewandowski and published by MDPI. This book was released on 2020-12-10 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen a paradigm shift in our understanding of groundwater–surface water interactions: surface water and aquifers were long considered discrete, separate entities; they are now understood as integral components of a surface–subsurface continuum. This book provides an overview of current research advances and innovative approaches in groundwater–surface water interactions. The 20 research articles and 1 communication cover a wide range of thematic scopes, scales, and experimental and modelling methods across different disciplines (hydrology, aquatic ecology, biogeochemistry, and environmental pollution). The book identifies current knowledge gaps and reveals the challenges in establishing standardized measurement, observation, and assessment approaches. It includes current hot topcis with environmental and societal relevance such as eutrophication, retention of legacy, and emerging pollutants (e.g., pharmaceuticals and microplastics), urban water interfaces, and climate change impacts. The book demonstrates the relevance of processes at groundwater–surface water interfaces for (1) regional water balances and (2) quality and quantity of drinking water resources. As such, this book represents the long-awaited transfer of the above-mentioned paradigm shift in understanding of groundwater–surface water interactions from science to practice.

Download or read book The Mediterranean Sea in the Era of Global Change 1 written by Christophe Migon and published by John Wiley & Sons. This book was released on 2020-02-19 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to its particular characteristics, the Mediterranean Sea is often viewed as a microcosm of the World Ocean. Its proportionally-reduced dimensions and peculiar hydrological circulation render it susceptible to environmental and climatic constraints, which are rapidly evolving. The Mediterranean is therefore an ideal site to examine, in order to better understand a number of key oceanographic phenomena. This is especially true of the Ligurian Sea where, due to its geology, oceanic conditions are found close to the coast. As such, 30 years ago, an offshore time-series site provided a fresh impetus to a long history of marine biology research, which has generated a very important body of data and knowledge. This is the first volume, in a two-volume series, that summarizes this research. Across these two books, the reader will find 13 chapters that examine the geology, physics, chemistry and biology of the Ligurian Sea ? always with the goal of providing key elements of oceanography in a changing world.

Download or read book Isotope Hydrology written by Joel Gat and published by World Scientific. This book was released on 2010 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the realm of the newly evolving discipline of environmental sciences, the stable-isotope methodology is being used to an ever-increasing extent, especially in the study of the water cycle and of paleo-climatology. This book introduces the rules of the game, by reviewing the natural variability of stable isotopes in the hydrosphere, describing the physico-chemical basis of isotope fractionation, and applying this knowledge to natural waters as they move through the hydrologic cycle from the ocean to the atmosphere, the biosphere and the lithosphere. There is a special focus on the processes at the surface?atmosphere and land?biosphere?atmosphere interfaces, since these are the sites of major changes in isotope composition. In response to the increasing awareness of our changing climate, a discussion on the global view of the changing water cycle, in the past and future, winds up the presentation.

Download or read book Seawater Intrusion in Coastal Aquifers written by Jacob Bear and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal aquifers serve as major sources for freshwater supply in many countries around the world, especially in arid and semi-arid zones. Many coastal areas are also heavily urbanized, a fact that makes the need for freshwater even more acute. Coastal aquifers are highly sensitive to disturbances. Inappropriate management of a coastal aquifer may lead to its destruction as a source for freshwater much earlier than other aquifers which are not connected to the sea. The reason is the threat of seawater intrusion. In many coastal aquifers, intrusion of seawater has become one of the major constraints imposed on groundwater utilization. As sea water intrusion progresses, existing pumping wells, especially those close to the coast, become saline and have to be abandoned. Also, the area above the intruding seawater wedge is lost as a source of natural replenishment to the aquifer. Despite the importance of this subject, so far there does not exist a book that integrates our present knowledge of seawater intrusion, its occurrences, physical mechanism, chemistry, exploration by geo physical and geochemical techniques, conceptual and mathematical modeling, analytical and numerical solution methods, engineering measures of combating seawater intrusion, management strategies, and experience learned from case studies. By presenting this fairly comprehensive volume on the state-of-the-art of knowledge and ex perience on saltwater intrusion, we hoped to transfer this body of knowledge to the geologists, hydrologists, hydraulic engineers, water resources planners, managers, and governmental policy makers, who are engaged in the sustainable development of coastal fresh ground water resources.
