Sustainability of Groundwater in the Nile Valley, Egypt


Book Description

Groundwater is the world’s largest source of fresh water, but its safe and sustainable exploitation remains a challenge. Egypt's Nile Valley aquifer is the most important renewable aquifer, accounting for approximately 85% of total groundwater use in Egypt. Egypt's long-term development and socioeconomic growth in the Nile Valley depends on this groundwater. Concerns about groundwater assessment, quality, management, and sustainability frame the current status of Nile Valley groundwater supplies. Proper knowledge of the current state of the groundwater quantity and quality in the Nile Valley is vital for the development and management of groundwater resources in Egypt. Due to Egypt's water scarcity, the projected decline in Nile River flow due to climate change, and the development of numerous Nile River basin projects, the situation is critical, and the consequences might be severe. Furthermore, Egypt's growing population puts significant strain on groundwater, which is the second most significant freshwater supply next to the surface water supply coming from the Nile River as Egypt’s share. Several books on the various aspects of Egypt's water resources have been published, but there is insufficient recent information on groundwater in the Nile Valley aquifer, which is essential for Egyptian populations for domestic and irrigation purposes. As a result, this book on the groundwater in the Nile Valley aquifer emerges to complete the picture of Egypt’s water resources as a good example of arid country located in MENA regions with many arid countries. Consequently, the lessons learned from this book could be beneficial to other countries in MENA regions, particularly those in North Africa.

Contrary Notions


Book Description

Internationally acclaimed, award-winning author Michael Parenti is one of America's most astute and engaging political analysts. Parenti's work has enlightened and enlivened readers for many years, covering a wide range of subjects. Here is a rich selection of his most lucid and penetrating writings on real history, political life, empire, wealth, class power, technology, culture, ideology, media, environment, sex, and ethnicity. Also included are a few choice selections drawn from his own life experiences and political awakening. Parenti goes where few political observers dare to tread. Time and again he takes the extra step beyond the parameters of permissible opinion, and time and again he succeeds in carrying the reader with him. The selections herein, that are reprinted from previously published works, have been revised and updated. Other offerings appear here for the very first time. "Radical in the true sense of the word, [Parenti] digs at the roots which...sustain our public consciousness."--Los Angeles Times Book Review "Prominent leftist public intellectual Parenti has built a reputation for himself as a trenchant, yet engaging and accessible, critic of capitalism, imperialism, and other forms of exploitation and violence and this diverse collection of his writings will not disappoint his fans (nor, probably, convince his detractors). Over the course of the collection he takes on the corporate media, intellectual repression in academia, the stolen presidential elections of 2000 and 2004 (not that he's a fan of Al Gore or John Kerry), right wing judicial activism, free-market orthodoxies and mythologies, racism, sexism, homophobia, postmodern attacks on Marxism, the distortions of dominant history, ill-informed demonizations of the Venezuelan political process, his own life, and many other topics."--Book News, Inc. "A prolific author, a charismatic speaker, and a regular guest on radio and television talk shows, Parenti communicates his message in an accessible, provocative, and historically informed style that is unrivaled among fellow progressive activists and thinkers."--Aurora Online Michael Parenti is a critically acclaimed author and an extraordinary public speaker. He received his Ph.D. in political science from Yale University and has taught at a number of colleges and universities, in the United States and abroad. He is the author of twenty books, including Superpariotism , The Assassination of Julius Caesar, Inventing Reality, and Democracy for the Few.







Useless Arithmetic


Book Description

Noted coastal geologist Orrin Pilkey and environmental scientist Linda Pilkey-Jarvis show that the quantitative mathematical models policy makers and government administrators use to form environmental policies are seriously flawed. Based on unrealistic and sometimes false assumptions, these models often yield answers that support unwise policies. Writing for the general, nonmathematician reader and using examples from throughout the environmental sciences, Pilkey and Pilkey-Jarvis show how unquestioned faith in mathematical models can blind us to the hard data and sound judgment of experienced scientific fieldwork. They begin with a riveting account of the extinction of the North Atlantic cod on the Grand Banks of Canada. Next they engage in a general discussion of the limitations of many models across a broad array of crucial environmental subjects. The book offers fascinating case studies depicting how the seductiveness of quantitative models has led to unmanageable nuclear waste disposal practices, poisoned mining sites, unjustifiable faith in predicted sea level rise rates, bad predictions of future shoreline erosion rates, overoptimistic cost estimates of artificial beaches, and a host of other thorny problems. The authors demonstrate how many modelers have been reckless, employing fudge factors to assure "correct" answers and caring little if their models actually worked. A timely and urgent book written in an engaging style, Useless Arithmetic evaluates the assumptions behind models, the nature of the field data, and the dialogue between modelers and their "customers."




Crustal Permeability


Book Description

Permeability is the primary control on fluid flow in the Earth’s crust and is key to a surprisingly wide range of geological processes, because it controls the advection of heat and solutes and the generation of anomalous pore pressures. The practical importance of permeability – and the potential for large, dynamic changes in permeability – is highlighted by ongoing issues associated with hydraulic fracturing for hydrocarbon production (“fracking”), enhanced geothermal systems, and geologic carbon sequestration. Although there are thousands of research papers on crustal permeability, this is the first book-length treatment. This book bridges the historical dichotomy between the hydrogeologic perspective of permeability as a static material property and the perspective of other Earth scientists who have long recognized permeability as a dynamic parameter that changes in response to tectonism, fluid production, and geochemical reactions.




Analytic Element Modeling of Groundwater Flow


Book Description

Modeling has become an essential tool for the groundwater hydrologist. Where field data is limited, the analytic element method (AEM) is rapidly becoming the modeling method of choice, especially given the availability of affordable modeling software. Analytic Element Modeling of Groundwater Flow provides all the basics necessary to approach AEM successfully, including a presentation of fundamental concepts and a thorough introduction to Dupuit-Forchheimerflow. This book is unique in its emphasis on the actual use of analytic element models. Real-world examples complement material presented in the text. An educational version of the analytic element program GFLOW is included to allow the reader to reproduce the various solutions to groundwater flow problems discussed in the text. Researchers and graduate students in groundwater hydrology, geology, andengineering will find this book an indispensable resource. * * Provides a fundamental introduction to the use of the analytic element method. * Offers a step-by-step approach to groundwater flow modeling. * Includes an educational version of the GFLOW modeling software.
