Groundwater Geophysics in Hard Rock
by Prabhat Chandra ChandraIn hard rock terrain, shallow water wells generally have a poor to moderate yield. Sinking wells deeply to tap yielding fracture zones often backfires, because the borehole may miss the saturated fracture zones at depths. A wrong approach to groundwater exploration in hard rock has therefore often led to unnecessary recurring expenditures and waste
Groundwater Law and Management in India: From an Elitist to an Egalitarian Paradigm
by Sarfaraz Ahmed Khan Tony George Puthucherril Sanu Rani PaulThis book presents a comprehensive analysis of the existing nature of India’s groundwater laws. In the backdrop of the gravity of groundwater crisis that threatens to engulf the country, the book examines the correlation between the imperfections in the law and water crisis and advocates a reform agenda to overhaul the legal framework. It accomplishes this objective by examining how some of the States and Union Territories regulate and manage groundwater through the legal instrumentality against the backdrop of the two conflicting paradigms: the “elitist” and the “egalitarian.” The book’s fundamental premise is that despite being an extraordinarily critical resource that supports India’s burgeoning population’s ever-increasing water demands, groundwater is abused and mismanaged. The key argument that it posits is that the elitist paradigm must give way to an egalitarian one where groundwater is treated as a common property resource. To place this message in perspective, the book’s introduction explains the dichotomy between the two paradigms in the context of groundwater. This sets the stage, after which the book is divided thematically into three parts. The first part deals with some of the general groundwater management concerns brought to the fore by the operation of the elitist paradigm. Since water is constitutionally a State subject, the second part analyses the groundwater legislations of different States and Union Territories set against their unique circumstances. As these laws do not dismantle the elitist paradigm that interlocks groundwater rights to land rights, the next part articulates the legal reform agenda where a case is made to re-engineer groundwater laws to reflect a more sustainable basis. The findings and arguments resonate with the situation in many developing countries around the world due to which the book is a valuable resource for researchers across disciplines studying this area, and also for policy makers, think tanks, and NGOs.Groundwater Management–Inter-state Water Conflicts–Aquifers–Water Markets–Water Security–Water Law Reform–Groundwater Law–Water Law–Sustainable Development–Hydrology

Groundwater Radon in the Taiwan Subduction Zone: A Natural Strain-Meter for Earthquake Prediction (Advances in Geological Science)
by Ming-Ching Tom KuoThis book presents the mechanism of in-situ radon volatilization and outlines the geological requisites to site a radon monitoring well for earthquake warning. A small fractured aquifer under undrained conditions is an effective natural strain meter for earthquake prediction. It shows significant merit on a local basis, and most importantly, the analysis can also be applied globally in subduction zones with similar tectonic settings and physical–chemical relationships.Between 2003 and 2010, anomalous declines in groundwater radon concentration were recurrently recorded at Antung, Taiwan, which are considered as precursory to local major earthquakes. The correlations between radon decline and earthquake magnitude are useful for early warning of local main earthquakes. The book consists of 7 chapters. Chapter 1 presents background information and the objectives of the book. Chapter 2 illustrates the methods of monitoring groundwater radon and a brief review of earthquake prediction research using groundwater radon. Chapter 3 provides the details of anomalous decrease in groundwater radon before the Taiwan Mw 6.8 Chengkung Earthquake of 2003. Chapter 4 provides the description of the mechanism of groundwater-radon volatilization. Chapter 5 shows the recurrent anomalous declines in groundwater radon concentration consistently recorded at Antung, Taiwan, prior to local main earthquakes that occurred between 2003 and 2010. Monitoring groundwater radon in small, unconfined fractured aquifers is explained in Chapter 6, followed by an analysis of correlating precursory declines in groundwater radon, precursory time with earthquake magnitudes for small, confined fractured aquifers in Chapter 7.

To wit, the book combines remote sensing and GIS techniques, runoff modeling, aquifer mapping, land use and land cover analyses, evapotranspiration estimation, crop coefficients, and water policy approaches. This will be of use to academics, policymakers, social scientists, and professionals involved in the various aspects of sustainable groundwater development, planning, and management.
Groundwater Sustainability: Conception, Development, and Application (Palgrave Studies in Environmental Sustainability)
by Robert E. MaceThis book will provide a comprehensive discussion of groundwater sustainability, including what it is, how its definition has changed over time, why traditional assessments of it are wrong, how assessments of it are ideally multidisciplinary efforts recognizing that policy is more controlling of outcomes than science, and why achieving it is difficult once pumping exceeds sustainable levels of pumping. The book will provide a nontechnical background of hydrogeology relevant to groundwater sustainability and present several case studies from around the United States and the world. The book has been designed to appeal to academics, students, and practitioners. Academics, particularly those just getting into the subject, will find the book a useful entry in terms of management concepts and political realities of attempting to achieve groundwater sustainability. It will also be useful to academics in that the book will include discussions on the history and development of groundwater sustainability and the practical aspects of aspiring to and achieving sustainable production. Although not a textbook, the book could be used as the basis for teaching a course or as a supplement to a hydrogeology or groundwater management class. Accordingly, the book will include questions and additional reading materials at the end of each chapter. This book will also be useful to practitioners through non-technical explanations of the sciences, discussions of the nuances of defining sustainability in aquifers, and the presentation of case studies where sustainable management has failed and succeeded.

Groundwater Vulnerability: Chernobyl Nuclear Disaster
by Boris Faybishenko Alexander Bohuslavsky Volodymir Bublias Thomas J. Nicholson Vyacheslav ShestopalovThe Chernobyl Nuclear Power Plant (NPP) disaster that occurred in Ukraine on April 26, 1986, was one of the most devastating in human history. Using this as a case study, the AGU monograph Groundwater Vulnerability: Chernobyl Nuclear Disaster is devoted to the problem of groundwater vulnerability, where the results of long-term field and modeling investigations of radionuclide transport in soil and groundwater, within the Ukrainian part of the Dnieper River basin (Kyiv region of Ukraine), are discussed. The authors provide a comprehensive review of existing literature on the assessment of groundwater vulnerability and then describe an improved methodology, which is developed based on integration of the methods of hydrogeological zonation and modeling of anomalously fast migration of radioactive contaminants from the land surface toward groundwater. This volume also includes the evaluation of the effect of preferential and episodic flow on transport of radionuclides toward the aquifers and risk assessment of groundwater vulnerability, which can further assist future researchers in developing remediation technologies for improving drinking water quality. Further, this volume sheds light on the consequences of groundwater contamination from nuclear disasters and assists with assessing the risks associated with contamination and developing effective remediation technologies. Volume highlights include discussions of the following: - Assessment of groundwater vulnerability to contamination from the Chernobyl nuclear disaster - Novel analytical results of the 25-year investigations of groundwater contamination caused by Chernobyl-born radionuclides - The wealth of data on different modes of radioactive transport in the atmosphere, water, and soils, and along the food chains - The hydrogeological and physico-chemical processes and factors in groundwater contaminated zones - The applicability of commonly used methods of the evaluation of groundwater vulnerability - A unique method of fluid dynamics that involves an anomalously fast migration of contaminants through zones of preferential flow from the land surface toward groundwater - Building confidence in the assessment of migration pathways of radionuclides in the biosphere - Assessment and prediction of the consequences of the nuclear accident, which can shed light on protection from global nuclear accidents - Analogue information for different nuclear waste disposal and environmental projects around the world

Groundwater and Subsurface Environments
by Makoto TaniguchiExcessive groundwater pumping, groundwater contamination, and subsurface thermal anomalies have occurred frequently in Asian coastal cities, greatly disturbing the urban aquifer and the subsurface environment. In this volume, the relationship between the stage of a city's development and subsurface environment issues have been explored. Intensive field surveys were done in Tokyo, Osaka, Seoul, Taipei, Bangkok, Jakarta, and Manila. New, advanced methods, including satellite, tracer techniques, and the social economy model, were developed to evaluate subsurface conditions. Groundwater storage and groundwater recharge rates, as well as the accumulation and transport of pollutants, have been compiled as integrated indices of natural capacities under climate and social changes, and used to evaluate the vulnerability risk for all cities. The indices have been made on a yearly basis for seven cities for a century (1900-2000). Using these indicators it is now possible to manage groundwater resources in a sustainable fashion. This volume is indispensable to researchers in hydrology, coastal oceanography, civil engineering, urban geography, social economy, climatology, geothermics, and urban management.
Groundwater and Water Quality: Hydraulics, Water Resources and Coastal Engineering (Water Science and Technology Library #119)
by Vijay P. Singh Ramakar Jha Vivekanand Singh L. B. Roy Roshni ThendiyathThis book deals with topics of current interest, such as climate change, floods, drought, and hydrological extremes. The impact of climate change on water resources is drawing worldwide attention these days, for water resources in many countries are already stressed and climate change along with burgeoning population, rising standard of living, and increasing demand are adding to the stress. Further, river basins are becoming less resilient to climatic vagaries. Fundamental to addressing these issues is hydrological modelling which is covered in these books. Further, integrated water resources management is vital to ensure water and food security. Integral to the management is groundwater and solute transport. The books encompass tools that will be useful to mitigate the adverse consequences of natural disasters. This book provides many new and innovative methods to assess groundwater and estimate water pollution. Groundwater recharge, solute transport, ground water modelling are some of the important variable used to estimate the groundwater movement, hydraulic gradient and pollution movement. The water quality is another important variable of river Ganga and its tributaries in India and other rivers over the globe.

Groundwater as a Key for Adaptation to Changing Climate and Society
by Makoto Taniguchi Tetsuya HiyamaThe book presents an overview of recent advances in knowledge related to the assessment and management of groundwater resources, giving special attention to the uncertainties related to climate change and variability. While proposing strategies of groundwater management as adaptation, alternative and resilience under the changing environments, this book also discusses new directions and initiatives of hydrological study, in particular on the groundwater. Groundwater is a major source of water across much of the world, and acts as a component of the global water cycle on the Earth. Groundwater has the capacity to balance large swings in precipitation and has the potential to supplement surface-water resources when they are close to the limits of sustainability such as during drought. Although groundwater is pivotal to sustain water supplies, these important resources are vulnerable to increased human activities and the uncertain consequences of climate change. This book presents that groundwater with longer resident time of water circulation can be an alternative water resources and environment in changing climate. Assessments of groundwater services and benefit as well as risk are important for sustainable groundwater uses under the climate change. Groundwater which is one of the leys of adaptation to climate change should be treated as common resources and environment beyond the tragedy of the commons and dilemma of the boundaries. While providing a comprehensive description of hydrogeological characteristics of groundwater systems, the present volume also covers important aspects of legal and institutional contexts required for groundwater resources management as well as social and economic considerations. This publication may contribute to an improved understanding of the impacts of climate change and human activity on groundwater resources, provides useful guidance for policy makers and planners to include groundwater into climate change adaptation schemes and strategies.

Groundwater in Ethiopia
by Seifu KebedeThis book provides a comprehensive description of groundwater resources in Ethiopia and its various dimensions (groundwater as resource, environmental functions, and socioeconomics). The prevailing knowledge of groundwater resources in Ethiopia (or elsewhere in Sub Saharan Africa) was based on geological and stratigraphic framework known nearly four decades ago (mainly 1960's and 70's). Thanks to the substantial geoscientific research since the 70's a new set of relevant geological/stratigrahpic data has been created that helps to re-define our understanding of groundwater resources in Africa as a whole and in Ethiopia in particular: a) For the first time the basement aquifer of Ethiopia has been described hydrogeologically based on genesis of regoliths (deep weathering and striping history); clear regional difference in groundwater potential is shown for the first time; comparative accounty has been given regarding groundwater occurrence in the generally low grade basement rocks of Ethiopia (Arabian Nubian shield) and high grade basement rocks of the rest of Africa. b) For the first time groundwater occurrence in multilayred sedimentary rocks account for spatial variation in degree of karstification; deformation history, and stratigraphy. c) The vast volcanic aquifers of Ethiopia which have previously classified based on their ages are now reclassified based on age, morphology (eg. groundwater in plateau volcanics, groundwater in shield volcanics) and aquifer structure. d) The loose alluvio lacustrine sediments which were known as least extensive in previous works based on areal cover are in fact shown to host the most voluminous groundwater resources in Ethiopia. These aquifers have now been described based on their geomorphology, extent, and genesis. The aim of this book is to use these newly created knowledge to redefine the understanding of groundwater resources in Ethiopia.
