This Special Issue presents the work of 30 scientists from 11 countries. It confirms that the impacts of global change, resulting from both climate change and increasing anthropogenic pressure, are huge on worldwide coastal areas (and critically so on some islands in the Pacific Ocean), with highly negative effects on coastal groundwater resources, which are widely affected by seawater intrusion. Some improved research methods are proposed in the contributions: using innovative hydrogeological, geophysical, and geochemical monitoring; assessing impacts of the changing environment on the coastal groundwater resources in terms of quantity and quality; and using modelling, especially to improve management approaches. The scientific research needed to face these challenges must continue to be deployed by different approaches based on the monitoring, modelling and management of groundwater resources. Novel and more efficient methods must be developed to keep up with the accelerating pace of global change.

Groundwater Contamination in Coastal Aquifers: Assessment and Management first describes groundwater contamination in coastal aquifers and then delves into specific topics surrounding various hydrogeochemical processes. Next, the book covers case studies of groundwater quality assessment using recent techniques, explains the various pollutants and contaminants in coastal aquifers, and covers management and remediation methods to control contamination in coastal aquifers. This key reference encompasses various topics in broader perspectives on groundwater contamination in coastal aquifers, providing a significant contribution to the field of hydrogeology. - Presents global case studies that show the reader how this issue is affecting sites around the world - Includes a remediation plan that solves problems surrounding the management of groundwater, water treatment techniques, and the management of available groundwater resources - Provides advanced techniques that can be applied and used as methodologies for solving groundwater issues

From the western United States to the Indian subcontinent, water issues have always been economic issues. Considered ubiquitous under the continents, groundwater varies considerably in depth, quality, accessibility, and availability. A unified discussion of groundwater and its economic importance, Groundwater Economics explores the application of e

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

Groundwater is becoming increasingly scarce while the demand for water continues to grow at a global scale. Understanding groundwater resources and their sustainable management is imperative for the future of groundwater use, conservation and protection. This revised and updated two-volume set, focused on sustainability, covers the economic values of groundwater production and use, including micro- and macroeconomic factors, groundwater markets, economic evaluation tools, climate change, transboundary issues and policy evaluation. It explores numerous applications and describes ways to evaluate the economics of groundwater use in the context of the larger ecosystem and the natural capital it provides. FEATURES OF THIS VOLUME Includes an important new chapter on groundwater sustainability management Addresses new examples of groundwater use that are applicable at both the local and international levels Provides the foundation for policy, program and project analysis for all major uses of groundwater Updates groundwater use data along with explanations of major production costs and use benefits Gives a new perspective on users’ competition for the subsurface environment Production, Use, and Sustainability of Groundwater, Second Edition, the first volume of the two-volume set Groundwater Economics, is a must-have for any professional or student who needs to understand, evaluate and manage water resources from a range of production and use perspectives affecting groundwater resource sustainability.

This book discusses how emerging groundwater risks under current and potential climate change conductions reduce available groundwater resources for domestic use, and agriculture and energy production. The topics discussed throughout this book are grouped into five sections; (i) Sea Level Rise, Climate Change, and Food Security, (ii) Emerging Contaminants, (iii) Technologies and Decision Support Systems, (iv) Surface Water-Groundwater Interactions, and (v) Economics, and Energy Production and Development. This book is unique and different from other groundwater hydrology books in that it uses a holistic approach in investigating the risks related to groundwater resources. This book will be of interest to a wide audience in academia, governmental and non-governmental organizations, and environmental entities. This book will greatly contribute to a better understanding of the emerging risks to groundwater resources and should help responsible stakeholders make informed decisions in this regard.

Groundwater management and conservation becomes a more and more important issue in the heavily urbanized coastal zones of the Asia-Pacific region. This volume presents a comprehensive overview of the status of coastal groundwater research in this diverse region. It includes latest methodologies and technologies to assess processes associated with coastal groundwater development. Case studies and local examples from a broad geographical range of continental shoreline and island settings give an understanding of the diversity of coastal aquifers and the groundwater recourses they harbour. Audience: By providing a clearer understanding of the hydrogeological and hydrochemical processes, this volume offers a critical tool to coastal researchers, geoscientists in related fields, water engineers, groundwater managers and decision makers as it illustrates the human and environmental impacts on coastal groundwater resources and the relationship to coastal zone management strategies and the development of sustainable management approaches.

Arid and semi-arid regions face major challenges in the management of scarce freshwater resources under pressures of population, economic development, climate change, pollution and over-abstraction. Groundwater is commonly the most important water resource in these areas. Groundwater models are widely used globally to understand groundwater systems and to guide decisions on management. However, the hydrology of arid and semi-arid areas is very different from that of humid regions, and there is little guidance on the special challenges of groundwater modelling for these areas. This book brings together the experience of internationally leading experts to fill a gap in the scientific and technical literature. It introduces state-of-the-art methods for modelling groundwater resources, illustrated with a wide-ranging set of illustrative examples from around the world. The book is valuable for researchers, practitioners in developed and developing countries, and graduate students in hydrology, hydrogeology, water resources management, environmental engineering and geography.
