With “integrated water resources management” (IWRM) the current buzzword in international circles, the real question is: how to operationalise a truly multidisciplinary approach to the effective management of shared watercourses.
Based largely on the actual experience of HELP (Hydrology for the Environment, Life and Policy), the overall aim of the book is to produce a series of case studies from around the world (from the Aral Sea to Zimbabwe) that demonstrate how the “gaps” between hydrology, water law and management are actually bridged in practice.
Is hydrological data relevant and used in the formulation of national and international water law and policy? Cases cited include examples of where this has happened and been successful or unsuccessful and where this has not happened and led to problems. This will act as a guide to how future water laws and polices can be made more effective via the use of accurate and up to date hydrological information.
Continuing in its forty-year history of providing students and professionals with a thorough grounding in the science and technology of groundwater hydrology, this third edition has been completely updated to reflect the tremendous changes in the field. A true essential reference, this book provides a unified presentation of the subject, treating fundamental principles, methods and problems encountered in the field as a whole.
Up-to-date coverage and a unique, multidisciplinary approach.
The ongoing effort to protect our valuable ground-water resources necessarily involves scientists and engineers from many disciplines. Ground-Water Microbiology and Geochemistry, Second Edition is designed to bridge the historical lack of communication among these disciplines by detailing-in language that cuts across specialties-the impact of microorganisms and microbial processes on ground-water systems.
Carefully revised to reflect the many recent discoveries that have been made in the field, the Second Edition begins with an overview of microbiology, ideal for hydrologists and others who may lack formal training in the field. These initial chapters systematically cover the kinds of microorganisms found in subsurface environments, focusing on their growth, metabolism, genetics, and ecology.
The second part of the book offers a hydrologic perspective on how microbial processes affect ground-water geochemistry in pristine systems. It also introduces the different classes of ground-water systems, and gives an overview of techniques for sampling subsurface environments. Readers gain an understanding of biogeochemical cycling in ground-water systems-in coverage unique to this book-and how ground-water chemistry can be used to study microbial processes in aquifer systems.
The final section of the book deals with the biodegradation of human-introduced contaminants in ground-water systems, with an up-to-date review of the physiology, biochemistry, and redox conditions that favor biodegradation processes.
Ground-Water Microbiology and Geochemistry, Second Edition is important reading for geoscientists, hydrologists, and environmental engineers, as well as for water planners and lawyers involved in environmental issues. It also serves as a compelling text for upper-level undergraduate and graduate courses in ground-water chemistry.
This edition of its popular predecessor has been significantly revised to increase flexibility in the presentation and maintain greater continuity of the material. Combining both theory and practical applications of empirical equations the text contains expanded treatment of water quantity and quality control, a detailed presentation of basic principles and use in analysis and design, hydrograph topics including synthetic and convolution techniques, practical and realistic case studies relating to design problems, and additional end-of-chapter problems. It provides new computer programs to explain complex concepts and solve large data-based problems. An additional appendix offers suggestions for classroom or lab problems.
The use of urban wastewater in agriculture is receiving renewed attention, with the increasing scarcity of fresh water resources in many arid and semi-arid regions of the world. Wastewater is a low-cost alternative to conventional irrigation water, although it may carry health and environmental risks.
This book critically reviews experience worldwide of these issues. Emphasis is placed on untreated wastewater use by means of field-based case studies from Asia, Africa, the Middle East and Latin America. It brings together a range of perspectives including economic, health, agronomic, environmental, institutional, and policy dimensions
