The natural scarcity of water in arid and semiarid regions, aggravated by man-made factors, makes it difficult to achieve a reliable water resources supply. Communities in these areas pay the price for thousands of years of water manipulation. Presenting important insight into the complexities of arid region hydrology, Engineering Hydrology of Arid
In arid and semi-arid regions groundwater is often the only natural resource for water supply. Therefore, stakeholders face great challenges in managing this resource in a responsible way. The problem is further amplified by population growth, increase in agricultural, industrial and municipal water consumption, and the threat of climate change. Therefore, an optimal use and management of the scarce groundwater resources is imperative. A precondition for this is a sound understanding of the particularities of the hydrogeology of arid and semi-arid regions as well as a proper knowledge of the water budget, water resources in storage, and water quality. This book summarizes the results of the conference "Hydrogeology of Arid Environments", which was held in March 2012 in Hannover (Germany). It gives an overview about current research on this topic with examples from arid and semi-arid areas from all over the world. The book is intended for scientists, engineers, hydrologists, hydrogeologists, and political decision makers interested in the water resources of arid and semi-arid environments.
This book provides comprehensive information about the water resources of the Arabian Gulf region, an area that is symbolic as an arid to extremely arid belt. Filling an information gap it provides in-depth analyses of both natural and human-related constraints on water resources, and presents a new vision on efficient management of available water resources.It contains an overview of the physical geography and climatic constraints on water resources, systematic inventory of available traditional and non-traditional water resources, water-related problems, water conservation and legislations, comprehensive water laws applicable to the region, and modern techniques of water resources investigation.This work meets the needs of scientists, environmentalists, engineers, planners and decision makers. Senior undergraduate, graduate students and researchers of the Gulf area, and more generally of arid regions, will also find this volume valuable.
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.
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.
Groundwater is an increasingly important resource to human populations around the world, and the study and protection of groundwater is an essential part of hydrogeology - the subset of hydrology that concentrates on the subsurface. Environmental isotopes, naturally occurring nuclides in water and solutes, have become fundamental tools for tracing
This book presents the most recent innovations, trends, concerns and practical challenges, and solutions in the field of water resources for arid areas. It gathers outstanding contributions presented at the International Water Conference on Water Resources in Arid Areas (IWC 2016), which was held in Muscat, Oman in March 2016. The individual papers discuss challenges and solutions to alleviate water resource scarcity in arid areas, including water resources management, the introduction of modern irrigation systems, natural groundwater recharge, construction of dams for artificial recharge, use of treated wastewater, and desalination technologies. As such, the book provides a platform for the exchange of recent advances in water resources science and research, which are essential to improving the critical water situation
Offers a comprehensive volume discussing groundwater problems in coastal areas, spanning fundamental science to practical water management.
Intermittent Rivers and Ephemeral Streams: Ecology and Management takes an internationally broad approach, seeking to compare and contrast findings across multiple continents, climates, flow regimes, and land uses to provide a complete and integrated perspective on the ecology of these ecosystems. Coupled with this, users will find a discussion of management approaches applicable in different regions that are illustrated with relevant case studies. In a readable and technically accurate style, the book utilizes logically framed chapters authored by experts in the field, allowing managers and policymakers to readily grasp ecological concepts and their application to specific situations. - Provides up-to-date reviews of research findings and management strategies using international examples - Explores themes and parallels across diverse sub-disciplines in ecology and water resource management utilizing a multidisciplinary and integrative approach - Reveals the relevance of this scientific understanding to managers and policymakers
This book contains the results and findings of the advanced research carried out in a pilot area with a thorough investigation of the structure and functioning of an aquifer in a granitic formation. It characterizes the hard rock aquifer system and examines its properties and behavior as well as systematically details the geophysical, geological and remote sensing applications to conceptualize such an aquifer system.
