Book Description
Qanats are ubiquitous, yet unseen, and a clever way to create streams where none exist in nature. For 3,000 years, they have made life possible in impossible places and still sustain life and livelihoods in many countries today. After 30 years of field research, Dale Lightfoot provides the first comprehensive study of the qanat and sheds new light on their unique locations and distribution, their origins and history, their ecology, current status and use. Qanats are remarkably engineered underground aqueducts, using gravity to bring water to villages and towns where reliable flowing surface water is scarce or absent. Although an ancient technology, more than 46,000 of them still flow around the world today, with their sustainable nature making them a focus of renewed interest. Richly illustrated with images and a series of original maps, this is the most complete record to date of the locations and distribution of qanats worldwide, including examples from the Middle East, North Africa, Europe, Central Asia, China, India, Mexico and South America.

Book Description
This book offers a ready solution for those who wish to learn more about this fascinating part of our water history and makes accessible to the wider world the traditional knowledge gained from building and maintaining qanats for more than 2,500 years. There is much more here than a summary of the nature and distribution of qanats, and a more extensive journey through the philosophy, methods, tools, and terminology of qanat design and digging than previously assembled. Where does one begin to dig to ensure that the qanat tunnel will flow with water? How are practical considerations of landscape factored into the design? How are water quality and discharge measured? How does excavation proceed through bedrock and unconsolidated soil and how is this knowledge of geology and pedology acquired? How are vertical wells and tunnels excavated to maintain proper air supply, light, and water flow? How does one deal with special problems like tunnel collapse, the accumulation of gasses and vapors, and the pooling of water during construction? How are tools and gauges designed, maintained, and used? How have qanats been incorporated into other structures like watermills, reservoirs, ice houses, and irrigation networks? And how are qanats cleaned, extended, maintained through the ages, and incorporated into modern water supplies? The great contribution of this work is the story it tells of the ingenuity and practical skills of the qanat masters who for centuries and generations have cut an uncountable number of tunnels through bedrock and alluvium using hand tools and homespun solutions to problems that would vex the most experienced university-trained engineers.

Book Description
Qanats and Historic Structures in Persia presents the early history of water science and includes the advanced knowledge held by Persians regarding the hydrologic cycle in general and groundwater flow in particular. It explains how the Persians understood the sources of rivers, streams, springs, and groundwater, at least seven centuries before it was known to western scholars, and how their use of underground water tunnels allowed them to transform deserts into centers of civilization and food production for thousands of years. It also presents an overview of ancient canals, weir bridges, dams, water storage structures, and water dividers constructed to supply water for irrigation and domestic needs. Presents numerous examples of how qanats are used throughout the world, including the Middle East, Africa, Asia, Europe, and South America. Includes descriptions and photographs of historic structures, some of which are still operational after hundreds of years. Written in an accessible and informative way, the book contains neither equations nor rigorous technical material. Examines the renowned scholars of the late ninth through twelfth centuries, namely the Persian Golden Era.

What if environmentally damaged landscapes could not only be remediated from an ecological standpoint, but also designed to replenish an entire community as well as the nature surrounding it? The Handbook of Regenerative Landscape Design incorporates ecology, engineering, sociology, and design elements into a new paradigm for environmental r

Book Description
Water is one of the world's threatened resources: it is also a substance of importance in Geology. For some years I have felt the need for a book that sets out the fundamentals of fluid mechanics, written for geologists rather than engineers. The efforts to repair my own deficiencies in this respect led me along various unfamiliar paths, few of which were unrewarding. This book is the result of my journeys through the literature and as a geologist in several parts of the world. It has been written for students of geology of all ages, in the simplest terms possible, and it has one objective: to provide a basis for an understanding of the mechanical role of water in geology. It has not been written for experts in ground water hydrology, or specialists in the fluid aspects of structural geology: it has been written for geologists like me who are not very good mathematicians, so that we can take water better into account in our normal geological work, whatever it might be. The fundamentals apply equally to mineralization, geochemistry, and vulcanology although they have not been specifically mentioned. It has also been written for the university student of geology so that he or she may start a career with some appreciation of the importance of water, and understanding of its movement.

Book Description
This book traces “water” back to the most primitive animistic notions that are still lingering on in the shape of such rituals as qanat marriage or rain-making. Water, in the Iranian philosophy, is used in an attempt to find an explanation for the genesis of the universe, as described in Zoroastrian Akhshij philosophy, according to which water is one of the four fundamental elements of the creation. The concept of time began to germinate in the Iranian mind, when they had to count the passage of time in order to divide their scarce water resources. Water became so omnipresent in Iranian culture that it reached even the most mysterious seclusion of the Sufi monks. In Iran’s local communities, water culture is a thread that runs through different types of production systems. This book goes beyond indigenous water knowledge and traditional irrigation techniques, and conceptualizes water as a pivotal element of Iran’s social identity, cultural dynamics and belief systems, where it examines the role of intermittent droughts in engendering and diffusing intangible cultural elements across the Iranian plateau. This book delves into Iran’s political organizations most of which were ensnared in a water-dependent lifecycle constituting a historical pattern described in this book as “hydraulic collapse” .
