How the Ancients of Mesa Verde Engineered Public Works Navajos called them "the ancient ones," the Anasazi. Monuments to their genius remain in Colorado's cliffside apartment houses, terraced fields, and ruins of a sprawling, medieval road system. But there are mysteries about the Anasazias well. Among them is how they were able to get enough water to sustain a civilization on a riverless mesa with infrequent rainfall. This full color essay by Kenneth R. Wright, a civil engineer, probes the technology behind the Anasazi's success.

An outline of a 1000 year chronicle of environmental and cultural history which attempts to explain broad patterns of interaction between humans and their environment. It uses North American geological and botanical remains, and looks at the behaviour of the Anasazi - prehistoric Pueblo Indians.

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.

There is no more fundamental resource than water. The basis of all life, water is fast becoming a key issue in today’s world, as well as a source of conflict. This fascinating book, which sets out many of the ingenious methods by which ancient societies gathered, transported and stored water, is a timely publication as overextraction and profligacy threaten the existence of aquifers and watercourses that have supplied our needs for millennia. It provides an overview of the water technologies developed by a number of ancient civilizations, from those of Mesopotamia and the Indus valley to later societies such as the Mycenaeans, Minoans, Persians, and the ancient Egyptians. Of course, no book on ancient water technologies would be complete without discussing the engineering feats of the Romans and Greeks, yet as well as covering these key civilizations, it also examines how ancient American societies from the Hohokams to the Mayans and Incas husbanded their water supplies. This unusually wide-ranging text could offer today’s parched world some solutions to the impending crisis in our water supply. "This book provides valuable insights into the water technologies developed in ancient civilizations which are the underpinning of modern achievements in water engineering and management practices. It is the best proof that "the past is the key for the future." Andreas N. Angelakis, Hellenic Water Supply and Sewerage Systems Association, Greece "This book makes a fundamental contribution to what will become the most important challenge of our civilization facing the global crisis: the problem of water. Ancient Water Technologies provides a complete panorama of how ancient societies confronted themselves with the management of water. The role of this volume is to provide, for the first time on this issue, an extensive historical and scientific reconstruction and an indication of how traditional knowledge may be employed to ensure a sustainable future for all." Pietro Laureano, UNESCO expert for ecosystems at risk, Director of IPOGEA-Institute of Traditional Knowledge, Italy
