To increase access to sustainable supplies of safe water for the poor, groundwater resources need to be exploited successfully, sustainably and economically on a much larger scale than they are at present. Unfortunately, techniques for finding and exploiting groundwater are not widely available. This book sets out to be a user-friendly guide to developing groundwater for rural water supplies. It is specifically designed and developed to meet the needs of rural water supply project staff in developing countries. It provides information on simple, effective techniques for siting wells and boreholes, assessing resource sustainability, constructing and testing the yield of boreholes and wells, and monitoring groundwater quality. The authors endeavour to set the technical aspects of rural water supply firmly in the relevant socio-economic context, so that guidance given is not in conflict with community aspects.

This book deals with the challenges for efficient groundwater management, with a focus on South Asia and India, providing a balanced presentation of theory and field practice using a multidisciplinary approach. Groundwater of South Asia is increasingly confronted with overuse and deteriorating quality and therefore requires urgent attention. Management of the stressed groundwater systems is an extremely complex proposition because of the intricate hydrogeological set-up of the region. Strategies for sustainable management must involve a combination of supply-side and demand-side measures depending on the regional setting and socio-economic situations. As a consequence, the challenges of efficient groundwater management require not only a clear understanding of the aquifer configuration, but also demand for the development of a comprehensive database of the groundwater occurrences and flow systems in each hydrogeological setting. In addition, drilling and well construction methods that are appropriate to different hydrogeological formations need to be implemented as well as real-time monitoring of the status of the groundwater use. Also corrective measures for groundwater that is threatened with depletion and quality deterioration need to be installed. Finally, the legal framework of groundwater needs to be rearticulated according to the common property aspect of groundwater. These challenges should revolve around effective groundwater governance by creating an atmosphere to support and empower community-based systems of decision-making and revisit the existing legal framework and groundwater management institutions by fostering community initiatives. This book is relevant for academics, professionals, administrators, policy makers, and economists concerned with various aspects of groundwater science and management.

Groundwater is Africa’s most precious natural resource, providing reliable water supplies for many people. Further development of groundwater resources is fundamental to increasing access to safe water across the continent to meet coverage targets and reduce poverty. There is also an increasing interest in the use of groundwater for irrigated agriculture as the climate becomes more variable. Sustainable development of the resource is not a trivial task and depends crucially on an understanding of the hydrogeology and people with the skills to make informed decisions on how groundwater can best be developed and managed in a sustainable fashion. Despite these obvious needs, however, little attention has been paid to the systematic gathering of information about groundwater resources in the past few decades, with the result that data are patchy, knowledge is limited and investment is poorly targeted. This book was written to start to bridge the knowledge gap. The 29 chapters are written by a combination of practitioners and researchers mainly from within Africa using experience from recent and ongoing projects. The chapters highlight the complexity and variety of issues surrounding the development and management of groundwater resources across Africa, and provide a snapshot of groundwater research and application in the early 21st century. Chapters range from strategic discussions of the role of groundwater in development and poverty reduction, to case studies on techniques used to develop groundwater, and modelling methods for managing groundwater systems.

Groundwater is an indispensable resource in many parts of the world, where it supports domestic water supply, irrigated agriculture and industry. Its increased, and often intensive, use during the last half century has created problems and raised concerns regarding the potential depletion of local aquifers, water quality degradation and various geologic hazards such as land subsidence and sinkholes. This volume includes contributions by experts from several countries who describe different groundwater management practices in their part of the world and discuss measures and actions in response to the challenges associated with the sustainability of groundwater use and the protection of the groundwater environment, as well as the evolution of legal and institutional framework needed for their implementation. It discusses past and present practices and various aspects of the regulatory and legal framework of groundwater management in Japan, China, India, Iran, Australia, the United States, Spain, Denmark, Switzerland and the European Union, and reviews recent efforts to improve the management of transboundary aquifer resources.

This paper reviews policy-related issues discussed in recent conferences that will affect groundwater development and management efforts in South Asia. Emphasis is given to policy issues surrounding emerging groundwater depletion and quality concerns, and issues concerning the equitable development of groundwater for poverty alleviation. The paper outlines the range of services that depend on groundwater resources and outlines the range of services that depend on groundwater resources to provide these services, and the complications stemming from the fragmented approach taken to water management throughout the region. A range of responses dealing with the management of the physical system is identified. In conclusion , the paper discusses institutional frameworks through which management responses could be implemented, in relation to both the range of approaches theoretically applicable and the existing institutional frameworks in place throughout South Asia

The importance of groundwater to India's economy and development prospects should not be underestimated. The resource is of importance as a source of drinking water and food security for the 950 million inhabitants of India, supplies 80 percent of water for domestic use in rural areas and perhaps 50 percent of water for urban and industrial uses. Over the last three decades, the rapid expansion in use of groundwater primarily for irrigation has contributed significantly to agricultural and overall economic development in India. Groundwater irrigation potential, the number of wells, and the number of energized pump sets have grown exponentially since the early 1950s. Groundwater now supplies more than 50 percent of the irrigated area and, due to higher yields in groundwater-irrigated areas, is central to a significantly higher proportion of total agricultural output. In addition, in drought years, groundwater represents the primary reliable source of irrigation. This rapid development in groundwater, however, has had a price. In many arid and hard-rock zones, increases in overdraft areas and associated water-quality problems are emerging. Sustainability of the resource base is thus critical for meeting an array of basic needs -from health to economic development.

Hydrological drought is a textbook for university students, practising hydrologists and researchers. The main scope of this book is to provide the reader with a comprehensive review of processes and estimation methods for streamflow and groundwater drought. It includes a qualitative conceptual understanding of drought features and processes, a detailed presentation of estimation methods and tools, practical examples and key aspects of operational practice. The methods are demonstrated using sample data sets and tools that are provided on the accompanying CD. The drought phenomenon and its diversity across the world are illustrated using a global set of daily streamflow series, whereas regional and local aspects of drought are studied using a combination of hydrological time series and catchment information. The book concludes with human impacts, ecological issues and examples of procedures for designing and operating water resources schemes. The majority of the examples are taken from regions where the rivers run most of the year. The material presented ranges from well established knowledge and analysing methods to recent developments in drought research. Its nature varies accordingly, from a more traditional textbook with its clear overview to that of a research paper, which introduces new approaches and methodologies for drought analysis. Also available in paperback, ISBN 0-444-51767-7.

The primary groundwater management issue in many countries today is pollution. The key to understanding the transport of a pollutant from the ground surface or near surface into an aquifer is an understanding of recharge. This allows the vulnerability of aquifers to pollution to be classified and appropriate land zones to be defined. This text provides an up-to-date description of the relationship between pollution, recharge and vulnerability set against the current groundwater protection policies of the UK and Ireland. There are keynote overviews for each topic.

Hydrodynamics of Time-Periodic Groundwater Flow introduces the emerging topic of periodic fluctuations in groundwater. While classical hydrology has often focused on steady flow conditions, many systems display periodic behavior due to tidal, seasonal, annual, and human influences. Describing and quantifying subsurface hydraulic responses to these influences may be challenging to those who are unfamiliar with periodically forced groundwater systems. The goal of this volume is to present a clear and accessible mathematical introduction to the basic and advanced theory of time-periodic groundwater flow, which is essential for developing a comprehensive knowledge of groundwater hydraulics and groundwater hydrology. Volume highlights include: Overview of time-periodic forcing of groundwater systems Definition of the Boundary Value Problem for harmonic systems in space and time Examples of 1-, 2-, and 3-dimensional flow in various media Attenuation, delay, and gradients, stationary points and flow stagnation Wave propagation and energy transport Hydrodynamics of Time-Periodic Groundwater Flow presents numerous examples and exercises to reinforce the essential elements of the theoretical development, and thus is eminently well suited for self-directed study by undergraduate and graduate students. This volume will be a valuable resource for professionals in Earth and environmental sciences who develop groundwater models., including in the fields of groundwater hydrology, soil physics, hydrogeology, geoscience, geophysics, and geochemistry. Time-periodic phenomena are also encountered in fields other than groundwater flow, such as electronics, heat transport, and chemical diffusion. Thus, students and professionals in the field of chemistry, electronic engineering, and physics will also find this book useful.

This book presents a unique and up-to-date summary of what is known about groundwater on our planet, from a global perspective and in terms of area-specific factual information. Unlike most textbooks on groundwater, it does not deal with theoretical principles, but rather with the overall picture that emerges as a result of countless observations, studies and other activities related to groundwater in all parts of the world. The focus is on showing the role and geographical diversity of groundwater—a natural resource of great importance in daily life, but poorly understood by the general public and even by many water sector professionals. The book starts by analysing groundwater in the context of the hydrological cycle. Subsequently, groundwater systems as physical units, with their boundaries mainly defined by geological conditions, are reviewed. The next chapter looks at groundwater as a resource, paying attention, among others, to its quantity and quality, to the differentiation between renewable and non-renewable resources, and to the techniques for withdrawing groundwater. This is followed by a systematic documentation of the quantities of groundwater withdrawn and used around the world, and of the corresponding shares of groundwater in each of the main water use sectors. After that, steadily growing needs for groundwater management interventions are identified, resulting from local human activities and global change (including demography, economic development and climate change). Finally, groundwater resources management is addressed and real-life cases are described that illustrate actions taken and experiences with different issues in different parts of the world. The authors attempted to write this book in such a way that it is accessible to a wider readership than just groundwater professionals. It will also benefit non-groundwater specialists who work in groundwater-related fields (water managers, land use planners, environmentalists, agronomists, engineers, economists, lawyers, and journalists), by broadening their understanding of groundwater and making them aware of the huge variety of groundwater settings. Groundwater specialists will use the book as a convenient reference on the geographical diversity of groundwater. Part of the contents or interpretations offered may even be new to them or enhance their knowledge of some aspects. The many maps, tables, and references will save much time for those who would otherwise have to search elsewhere for basic information on the globe’s groundwater.
