    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.
