A large part of the global population lives in arid lands which have low rainfall and often lack the water required for sustainable population and economic growth. This book presents a comprehensive description of the hydrogeology and hydrologic processes at work in arid lands. It describes the techniques that can be used to assess and manage the water resources of these areas with an emphasis on groundwater resources, including recent advances in hydrologic evaluation and the differences between how aquifer systems behave in arid lands versus more humid areas. Water management techniques are described and summarized to show how a more comprehensive approach to water management is required in these areas, including the need to be aware of cultural sensitivities and conditions unique to many arid regions. The integration of existing resources with the addition of new water sources, such as desalination of brackish water and seawater, along with reusing treated wastewater, will be required to meet future water supply needs. Also, changing climatic conditions will force water management systems to be more robust so that future water supply demands can be met as droughts become more intense and rainfall events become more intense. A range of water management techniques are described and discussed in order to illustrate the methods for integrating these measures within the context of arid lands conditions.
The Routledge Handbook of Latin America and the Environment provides an in-depth and accessible analysis and theorization of environmental issues in the region. It will help readers make connections between Latin American and other regions' perspectives, experiences, and environmental concerns. Latin America has seen an acceleration of environmental degradation due to the expansion of resource extraction and urban areas. This Handbook addresses Latin America not only as object of study, but also as a region with a long and profound history of critical thinking on these themes. Furthermore, the Handbook departs from the environment as a social issue inextricably linked to politics, economy and culture. It will be an invaluable resource for those wanting not only to understand the issues, but also to engage with ideas about environmental politics and social-ecological transformation. The handbook covers a broad range organized in three areas: physical geography, ecology and crucial environmental problems of the region, key theoretical and methodological issues used to understand Latin America's ecosocial contexts, and institutional and grassroots practices related to more just and sustainable worlds. The Handbook will set a research agenda for the near future and provide comprehensive research on most subregions relative to environmental transformations, challenges, struggles and political processes. It stands as a fresh and much needed state of the art introduction for researchers, scholars, post-graduates and academic audiences on Latin American contributions to theorization, empirical research and environmental practices.

The renowned geologist James D. Forbes (1809 68) presents an account of his systematic exploration of alpine mountain regions and glaciers in this important 1843 publication. Forbes' graphic descriptions of alpine scenery and his mountaineering feats are combined with detailed records of his scientific research and experiments. The study cemented Forbes' reputation in the field, which was later to be commemorated by the naming of the Aiguille Forbes in the Alps and of Mount Forbes in both Canada and New Zealand. The aim in writing the book, says Forbes, was to 'illustrate the physical geography of a particular district in one of the most frequented regions of the Alps'. In doing this, he draws upon the important work of the 'bold mountaineer' Horace B n dict de Saussure, whose feats and achievements Forbes clearly admired. The book is still viewed today as one of the most influential and important publications on mountaineering.

This book provides a comprehensive analysis of the benefits and challenges of intensifying groundwater irrigation in Sub-Saharan Africa (SSA) for improving smallholder agrarian livelihoods. Only about 3% of the groundwater resources of Sub-Saharan Africa are used for irrigated agriculture despite the subcontinent’s relative abundance of groundwater. The majority of the region’s smallholders are highly dependent on seasonal dryland cropping, making them extremely vulnerable to uncertain weather patterns and droughts. Improved irrigation capabilities through sustainable groundwater development could unleash smallholder farming and make it a major driver of economic growth, poverty reduction, climate resilience, and improved food security. So, why is groundwater so underused? Tapping into groundwater requires a major shift in farming practices and it has its own challenges and requirements – smallholder access to land and finance for irrigation infrastructure and equipment, gendered and equitable adoption options. This whole list is framed in terms of what the smallholder farmers need. Hence, this should also be put in this context, supply chains, energy access, resource availability, and institutional support. The chapters in this book present a picture that is not only heterogeneous across the region, but also hold some common denominators. They serve to enrich the discourse and help better understand the barriers along the pathways toward the sustainable and transformative adoption of groundwater irrigation. The scientific information provided herein would be of interest to researchers, practitioners, decision makers and planners with interest in the region. This book was originally published as a Special Issue of Water International journal.

Excessive 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.

Urban water management has to take an integrated approach that prioritizes sustainable drainage systems (SuDS) over gray infrastructure. This book elaborates on the planning and evaluation of pipework drainage systems with a focus on modern-day constraints to deliver a solution that favors sustainability as the overarching goal. The book includes a technical section on design of gray and green infrastructure, considering the total lifecycle costs of drainage systems. Advanced computer simulation techniques are discussed after covering the derivation of both standard and empirical equations for appropriate hydrology and hydraulics. The book provides an incorporation of reliability analyses for both green and gray infrastructure starting with techniques for forecasting flows, hydraulic performance, and lifecycle costs. The work also involves 3-D modeling, geospatial and big data analysis, and how these techniques are applied into city management—particularly beneficial to municipal engineers who are increasingly becoming involved in mapping the underground. Soil mechanics and subsurface drainage systems are analyzed and structural aspects of sewers are included. Finally, soil behavior in shear, retaining wall structures, and tunneling is briefly featured in the book. This book will be of interest to (under)graduate and postgraduate engineering students, drainage engineers, urban planners, architects, water engineers, developers, construction contractors, and municipal engineers.
Sustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses. Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to "democratize" membrane filtration have been presented. Riverbank filtration is a "natural" filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.
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.

The book presents a critical and comparative analysis of the hydropolitical landscape of African transboundary river basins which, for much of the past century, have been affected by water scarcity. River and lake basins can become a source of tension and conflict due to a complicated mix of environmental, demographic, diplomatic, historical and geopolitical factors. This book, however, specifically focuses on the important, and often under looked, role played by scarcity in generating or exacerbating conflicts in shared river basins. Asserting that transboundary river basins tie states into a web of interdependence, this book raises awareness of how water scarcity, or the depletion of water resources, complicates this relationship as nations are forced to look beyond their own borders to meet the demand for water to satisfy multiple needs. Taking a comparative approach, it examines three shared basins: the Orange-Senqu, the Nile and the Niger River basins. While situated in different regions, all three basins are marked by serious environmental challenges that are detrimental to combustible hydropolitics over such shared water resources and they provide fascinating insights into the links between climate variability and change, water resources, human security, conflict, adaptation and regime capacity. Overall, this book argues that conflict over transboundary resources can be prevented given the establishment of norms, rules, and the role of external actors that help regulate state behaviour and control their impacts. This book will be of great interest to students and scholars of water resource management, hydropolitics, environmental conflict, resource scarcity and international relations. It will also be of interest to policymakers involved in transboundary water resource governance.
The over-exploitation of groundwater and marked changes in climate over recent decades has led to unacceptable declines in groundwater resources. Under the likely scarcity of available water resources in the near future, it is critical to quantify and manage the available water resources. With increasing demand for potable water for human consumption, agriculture, and industrial uses, the need to evaluate the groundwater development, management, and productivity of aquifers also increases. Laboratory Manual for Groundwater, Wells, and Pumps serves as a valuable resource and provides a multi-disciplinary overview for academics, administrators, scientists, policymakers, and professionals involved in the managing sustainable groundwater development programs. It includes practical guidance on the measurement of groundwater flow, soil properties, aquifer properties, wells and their design, as well as the latest state-of-the-art information on pumps and their testing, and groundwater modeling. Features: Covers geographic information system-based studies, advanced methodologies, and their applications and groundwater modeling Examines groundwater exploration, planning and designing, and methods for formulating strategies for sustainable management and development Serves as a reference for practitioners on practical applications and frequently occurring issues of ground-water investigations, development, and management.
The focus of municipalities has been on the supply of sufficient water quantities to the public with less attention paid to water quality. The deteriorating quality of raw water sources necessitates increased attention to water quality with professional scientists playing a central role at municipalities and water boards together with professional engineers. With many stringent regulations on the quality of drinking water and recreational water bodies, the young municipal chemist needs a handy manual to assist in the often neglected and complicated field of municipal water management. Grounded in Science, Introduction to Municipal Water Quality Management not only links theory and regulations in practice but also offers simple numerical examples to better understand the rules and encourage a quantitative application to everyday problems. Developed from a series of lectures between 2015 and 2019, Introduction to Municipal Water Quality Management will give young professionals the confidence to analyse their results and apply their knowledge in a numerical fashion.
The key to the solution of geological hazards such as Karst water inrush and mud burst in tunnel lies in the accurate prediction or detection of Karst and groundwater. By means of on-site monitoring, theoretical analysis and indoor simulation experiments, the authors conduct in-depth research on the characteristics of water-bearing media and their mechanism of action, and explored the relevance of "Karst morphology", "Karst groundwater" and "fractal characteristics". An evaluation model of Karst development degree based on hydrochemical kinetic parameters and fractal index of Karst morphology is established. Based on the combination of Karst groundwater dynamics, hydrochemistry, water-rock interaction theory and fractal theory, the hydrochemical Kinetics and fractal index evaluation technique for Karst development is proposed. It provides a new theory and method for improving the accuracy of Karst and groundwater forecasting. The research results are of practical and guiding significance to the construction, Karst geological disasters prevention and management of various underground projects in Karst areas. Engineers and technicians, hydrogeological engineering geologists, and college students engaged in tunnel and underground engineering will find it valuable.

Groundwater is invisible, but its impact is visible everywhere. Everything around us relies on groundwater, our drinking water and sanitation, our food supply and our natural environment. Yet because it is invisible, information, management and governance of groundwater is often poor and inadequate. This book contributes to UN Water Groundwater year (2022), and to the effort of "making the invisible, visible". Through worldwide case studies ranging from the Americas (California, Brazil), to Asia (India, Iran, Lao PDR, Nepal), Africa (Malawi, Tanzania, South Africa) and the MENA region (Lebanon, Morocco, Yemen), including cases of transboundary aquifers, the chapters in this edited volume reflect important recent advances in interdisciplinary knowledge on the governance, management, practice and science-policy interfaces of groundwater. An insightful resource for researchers and planners in the field of environmental policies, water laws, climate change and groundwater governance, this book comes with a new Introduction. The other chapters were originally published in Water International. |
